The Power & Energy Logger Model PEL 105 provides all the necessary functions and features for recording power/energy data for most 50Hz, 60Hz, 400Hz, and DC distribution systems worldwide. The instrument measures phase-to-phase (U12, U23, U31), phase-to-neutral (V1, V2, V3) and neutral-to-ground/earth (VNE) voltage up to 1000V in measurement Category IV, with pollution degree 4 (IEC 61010-1 Ed3). The instrument also measures phase (I1, I2, I3) and neutral (IN) current, using a variety of external current probes/sensors. A total of 17 types of electrical hookups are supported.

This measurement data is then used to calculate:

Power (VA, W, and var)

Energy (VAh, Wh (source and load), and varh (4 quadrants))

Power Factor (PF), Cos φ, and Tan φ

Crest Factor

Total Harmonic Distortion (THD) for voltages and currents

Harmonics from the fundamental signal up to the 50th order for 50/60Hz voltages and currents

Frequency measurements

RMS and DC measurements @ 128 samples/cycle (each phase simultaneously)

Other features include:

Measurements are sampled every 200ms and 1s, and can be aggregated from 200ms to 1 hour and stored in a removable SD card or SDHC card (up to 32GB). For 50 and 60Hz systems, 200ms aggregation is calculated every 10 or 12 cycles, respectively. For 400Hz systems, aggregation is performed every 80 cycles.

Aggregated harmonics represent the minimum and maximum values of aggregated quantities for a given duration. These values can be displayed on the LCD front panel display, or on the computer via the DataView PEL Control Panel.

The instrument can be powered from line voltage terminals or an AC/DC power adapter.

The instrument can be connected to a computer running DataView data analysis software via Wi-Fi, Bluetooth®, network, USB, or point-to-point Ethernet cable.

The instrument front panel interface includes LED status indicators, screens that appear on the LCD, and buttons to navigate these screens, select options, and enter data. The components are (referring to Figure 1 in the PDF):

1. USB Port

2. Ethernet Port

The instrument provides four current and five voltage input terminals. To help organize these connections, 12 sets of color-coded rings and inserts are supplied with your instrument. Use these ID markers to identify the leads and terminals:

1. Detach the appropriate inserts and place them in the holes provided over the terminals (larger inserts for current terminals, smaller inserts for voltage terminals).

2. Clip the rings of the same color to the ends of the lead you will connect to the terminal.

The input terminals have:

1. Holes for color-coding clips

2. Current terminals

3. Voltage terminals

NOTE: In this manual, the symbol (e.g., a button icon) indicates when you need to press a button to perform a task. For example, a Control button icon represents “press the Control button.”

The LCD Screen displays status icons, bargraphs (percentage of full range/load), mode icons, and units of measure.

The Status & Mode icons on the top and bottom of the display indicate the following information:

NOTE: As a screen saver feature, when the instrument is ON and there is no activity on the user interface for approximately three minutes, the LCD automatically enters Backlight Standby mode. In this mode, measurements and recordings stay active but the LCD backlight turns OFF. To restore the backlight, press any navigation button.

On the left side of the front panel is a vertical row of LEDs which provide the following information:

In addition, the Power (①) button (described in § 2.4) glows green when the instrument is running on phase voltage power, and blinks red once per second when phase voltage power is disabled. (See also § 3.1.1.)

Data recording sessions are stored in the included 8GB SD card, which also accepts FAT32 SDHC cards up to 32GB capacity. If the SD card is unformatted, you will need to format it before use. Formatting can be done through a Microsoft Windows command, or through the DataView PEL Control Panel.

To install the SD card:

1. Locate the card slot on the front panel (see Item 15 in Figure 1 of the PDF).

2. Ensure that the write-protect sliding tab on the card is in the “unlock” position (towards the metal contacts).

3. Insert the SD card into the slot, with the metal contacts facing up (towards the top of the instrument).

4. Press the SD card into the slot until it clicks in place.

5. Press the attached cap into the card slot to ensure waterproofing.

6. If the SD Card is not formatted, the SD Card LED glows red. To format the installed card, open the PEL Control Panel (see § 6 of the PDF). Click Instrument in the menu bar and select Configure. Then click Format SD-Card in the General tab of the Configure Instrument dialog box, and click Yes to confirm.

When the card is installed and ready for use, the SD Card LED glows steady green. To remove a card, press down on it until the card unclicks. It will pop up, allowing you to pull it from the slot.

The instrument can operate on three different sources of power:

External power provided by plugging into an AC outlet with the AC adapter. When you connect the instrument to an AC outlet, it automatically turns ON. The instrument will always run on external AC power when plugged in, even if phase power and/or battery power are also available.

Phase power provided through line voltage at the terminals. If AC wall power is disconnected, the instrument runs on phase voltage power if it is available and enabled.

Battery backup power. If neither external AC power nor phase voltage is available, the instrument runs on battery power.

Powering the instrument through phase voltage power requires no special preparation or equipment; simply connect two voltage leads to an AC power line, connect the leads to the instrument using any available voltage terminals (see § 3 of the PDF), and unplug the external AC adapter if connected. By default, the instrument will immediately begin drawing phase power from the line.

The Power (①) button glows green when the instrument is running on phase power. In this situation, the instrument cannot be turned OFF via the (①) button.

Note that you cannot power the instrument from a DC network. Also note that if the AC adapter is plugged in, the instrument will use this source instead of phase power.

You can disable the phase power feature by pressing the Control button and Power button (①) simultaneously for two seconds. When you do this, (①) blinks red once every two seconds, indicating the instrument cannot run on phase power. Pressing the Control button and Power button (①) simultaneously for two seconds re-enables this feature. You can also disable and enable this feature through the DataView PEL Control Panel (see § 6 of the PDF).

The PEL 105 is equipped with a NiMH battery. Before the first use, start by fully charging the battery.

Connect the supplied power cord to the instrument and AC power. The device will automatically turn ON.

The Battery LED lights; it will go out only when the battery is fully charged.

A low battery charging takes approximately 5 hours.

Fully charging the battery may take up to 5 hours if the battery is at or near complete discharge. If after 5 hours the Battery LED does not turn OFF, operate the instrument on battery power until the battery runs low, and then repeat the charging procedure.

In normal operation, a fully charged battery will provide power for up to one hour before requiring another charging session (although this period may be shorter if the instrument is actively using Bluetooth or Wi-Fi to communicate). The Battery LED glows red when the battery is low and in need of charging.

Turning the Instrument ON:

On AC power or phase voltage power, the instrument automatically turns ON when you connect it.

On battery power, you must press the Power button (①) for two seconds to turn ON the instrument.

Turning the Instrument OFF:

The procedure for turning OFF the instrument depends upon the power source. First check to see whether or not a recording is scheduled or in progress (the REC LED blinks twice every five seconds when a recording is active). If so, either stop the recording, or wait until it is finished. Then do one of the following:

AC power (indicated when the External Power LED is lit): Unplug the AC power adapter, and then press the Power button (①) for two seconds. When all LEDs light up simultaneously, release (①).

Phase voltage power (indicated when (①) glows green): Disconnect the voltage terminal leads from the instrument, then press (①) for two seconds and release it when all LEDs light up simultaneously.

Battery power: Press (①) for two seconds and release it when all LEDs light up simultaneously.

In addition, the instrument includes a feature that automatically turns it OFF after a period of inactivity when running on battery power. This period, which is defined through the PEL Control Panel, can be set to 3, 10, or 15 minutes. It can also be disabled.

To communicate via a Bluetooth connection, check the Bluetooth LED on the instrument. If this is OFF, Bluetooth is disabled. To enable Bluetooth:

1. Press and hold down the Control button. After a few moments the Recording REC LED lights up; continue to press the button until the Bluetooth LED lights up.

2. Release the Control button; when you do the Bluetooth LED lights and remains lit, indicating Bluetooth is now enabled.

3. To disable Bluetooth, press the Control button until the Bluetooth LED lights up; then release the button. The Bluetooth LED will turn OFF.

In addition to enabling and disabling Bluetooth, the PEL Control Panel allows you to change the instrument’s Bluetooth name, enable Bluetooth password-protection, and select whether or not the instrument is visible to other Bluetooth devices.

The procedure for enabling Wi-Fi is similar to the process for enabling Bluetooth:

1. Check the Wi-Fi LED. If this is OFF, press and hold down the Control button until the Wi-Fi LED lights up.

2. To disable Wi-Fi, press the Control button until the Wi-Fi LED lights up; then release the button.

You can also enable and disable Wi-Fi through the PEL Control Panel. In addition, you can change the SSID (Service Set Identifier) name, and define a Wi-Fi password via the PEL Control Panel. (Note that the default Wi-Fi password is printed on a label placed inside the instrument’s cover.)

Before you can use the instrument for the first time, you must set a number of configuration variables. Full setup and configuration is performed through a computer running the DataView PEL Control Panel (see § 6 of the PDF). This includes setting the instrument’s time and date (§ 6.4 of the PDF).

In addition, a subset of configuration settings can be performed directly on the instrument via its LCD interface, including:

Select the hookup for the electrical distribution system under test

Set voltage and current ratios appropriate for the connected probes or sensors

Set the aggregation period for a recording session

Review instrument settings, such as date and time

Before you can perform any configuration on the instrument, the Control button must be enabled. This button is enabled and disabled through the PEL Control Panel. When this button is disabled, Configuration mode (wrench icon) displays the word LOCK, and no configuration screens are available. (Note that LOCK also appears if the PEL Control Panel is actively configuring the instrument.) If the Control button is disabled, enable it as follows:

1. Open the PEL Control Panel.

2. Ensure that the instrument is connected by checking its status in the PEL Network frame. If not, reconnect it by highlighting the instrument, selecting Instrument in the menu bar, and clicking Reconnect Instrument.

3. Select the instrument, and click Instrument in the menu bar.

4. Select Configure. This displays the Configure Instrument dialog box.

5. De-select the checkbox “Lock out the Control button on the instrument front panel.”

6. Click OK to save the change.

Consult the PEL Control Panel Help system for assistance in completing the preceding steps.

NOTE: Before changing any setup or configuration setting, ensure that no recording is active or pending on the instrument.

Configuration mode enables you to change several settings, including:

Hookup type

Primary and secondary nominal voltage

Primary nominal current

Primary nominal neutral current

Aggregation period

To enter Configuration mode, press either Left (◄) or Right (►) button until the Configuration icon (wrench) is highlighted. Note that there are several situations that prevent you from making changes in Configuration mode:

The instrument is currently being configured by the PEL Control Panel.

Local configuration is locked (disabled) through an option in the PEL Control Panel. This prevents configuration even when the instrument is disconnected from the Control Panel.

A recording session is in progress.

If any of these situations is in effect, the word LOCK appears on the screen. Otherwise, the Hookup configuration screen appears (e.g., displaying “HOOK UP” and the current hookup like “3P-3WΔ2”). This is the top-level screen in Configuration mode and serves as the starting point for all configuration tasks.

The Hookup configuration screen lets you select the type of hookup for the electrical distribution system under measurement. This must be the same physical hookup as the probes/sensors (see § 4 of the PDF).

To select the hookup:

1. Press Enter. The displayed hookup type blinks, indicating you are now in edit mode.

2. Press Up (▲) or Down (▼) to navigate through the available hookup types.

Options are:

Note that this list is not cyclical; pressing Down (▼) while 1P-2W is displayed (or pressing Up (▲) while dC-4W is displayed) has no effect.

When the desired hookup type appears, press Enter to save it. The hookup type stops blinking, indicating you have exited edit mode.

Configuration mode lets you set a voltage ratio for the transformer being measured (if necessary). This involves setting a primary nominal voltage and secondary nominal voltage for the transformer. To do this, display the Hookup configuration screen and proceed as follows:

1. Press Down (▼) to display the Primary Nominal Voltage (PT PRIM) configuration screen (e.g., “PT PRIM” with a voltage value).

2. Press Enter. The first digit of the primary nominal voltage value blinks. (Note that although this value is displayed on two separate lines, it is a single number.)

3. Press Left (◄) or Right (►) to navigate through the displayed digits.

4. When the desired digit is selected, press Up (▲) or Down (▼) to change its value. The primary nominal voltage can range from 50 volts to 650000 volts.

5. Press Enter when the displayed voltage is correct.

6. Press Down (▼) to display the Secondary Nominal Voltage (PT SEC) configuration screen. This functions similarly to the Primary Nominal Voltage screen. Allowable secondary nominal voltage values range from 50 to 1000V.

7. If a probe or sensor is connected, and the type of probe/sensor supports setting a transformer ratio, you can configure the primary nominal current appropriate for the probe. To do this, press Down (▼) at the Secondary Nominal Voltage configuration screen. This displays the Primary Nominal Current (CT PRIM) configuration screen (e.g., “CT PRIM” with a current value).

The primary nominal current depends on the type of probe/sensor or adapter:

AmpFlex/MiniFlex: 100, 400, 2000, or 10000A

MN93: automatic 200A

MN193 5A range: 5 to 25000A

MN193 100A range: automatic 100A

S93: automatic 3500A

SL261: 10 or 1000A

SR193 and MR193: automatic 1000A

5A Adapter Box: 5 to 25000A

BNC Adapter: 1 to 25000A

8. Press Enter and use the directional buttons to select the appropriate value.

9. Press Enter to save your changes.

10. If a probe or sensor is connected to the instrument’s neutral input terminal, pressing Down (▼) at the Primary Nominal Current configuration screen displays the Primary Neutral Current screen. This screen functions similarly to the Primary Nominal Current screen. Allowable values are:

AmpFlex/MiniFlex: 100, 400, 2000, or 10000A

BNC Adapter: 1 to 25000A

When recording data (see § 5 of the PDF), the instrument performs measurement aggregation. This involves determining the average value for a measured parameter over a user-specified time interval. This interval is called the aggregation period, and can be set in Configuration mode. To do this:

1. From the Hookup configuration screen, press Up (▲) to display the Aggregation Period screen (e.g., “AGG,PER!” with a time value).

2. Press Enter to select the aggregation period value.

3. Press Up (▲) or Down (▼) to make changes. Available options in minutes are 1 through 6, 10, 12, 15, 20, 30, and 60.

4. Press Enter to save your changes.

Information mode enables you to review instrument information and settings. To enter Information mode:

1. Press Left (◄) or Right (►) until the Information icon (i) is selected.

2. Press Up (▲) or Down (▼) to cycle through a series of read-only screens.

These screens display settings for the following:

Hookup

Primary nominal voltage

Secondary nominal voltage

Primary nominal current

Primary nominal neutral current (when available)

Aggregation period

Date and time

LAN IP address

WiFi IP address

Firmware revision number

The Model PEL 105 works with a variety of current probes and sensors. To connect a probe (e.g., AmpFlex® Model A196-24-BK) to the electrical network under measurement, do the following:

1. Connect the probe lead onto the appropriate current terminal. Which terminal to use depends on the hookup type, as explained later in this section. Note: When using AmpFlex A196-24-BK probe, be sure to screw the lead onto the threaded terminal to ensure water-tight (IP67) operation.

2. Open the probe by pressing the release levers on the side of the coupling and pulling out the end (for flexible loop probes).

3. Wrap the probe around the electrical cable to be measured.

4. Close the probe by inserting the end back into the coupling.

This is the basic connection procedure for flexible loop probes. Clamp-on probes require a similar connection process.

NOTE: When connecting to the electrical network, be sure to observe all safety precautions as stated in the documentation that accompanies the probes and sensors. For all hookups, ensure that the arrow on the probe is directed towards the load. This provides proper phase angle for power measurements and other phase-sensitive measurements.

5. REC LED: When a recording is attempted by pressing the Control (Start/Stop) button, the REC LED should start blinking twice every 5 seconds. If it doesn’t, or shows a different pattern, consult the LED status table (§ 2.6 of the PDF).

6. Attempt via PEL Control Panel: Try starting a recording session using the DataView PEL Control Panel. This might provide more specific error feedback.

7. Contact Support: If the issue persists, contact AEMC Instruments.

If recording sessions end prematurely:

1. SD Card Full or Error:

The SD card may have become full during the recording. The SD Card LED might indicate this (blinking green if it will be full soon, or orange if full).

There might be an error writing to the SD card (e.g., card corruption, intermittent connection). Try a different, reliable SD card after formatting it.

2. Power Interruption:

If running on battery, the battery may have depleted. Ensure continuous power supply (AC adapter or sufficient phase power) for long recording sessions.

Check for loose power connections.

3. Overload Condition: If an input overload condition occurs (Overload LED ON), it might interrupt recording or affect data integrity.

4. Instrument Malfunction or Software Glitch: An internal issue or a software glitch could cause this. Ensure firmware is up to date. Try power cycling the instrument.

5. Environmental Factors: Extreme temperatures or electromagnetic interference could potentially affect operation, though the PEL 105 is designed for outdoor use.

6. Scheduled Stop: If the recording was scheduled via PEL Control Panel, check if a stop time was inadvertently set.

7. Contact Support: If the problem is persistent and not related to SD card or power, contact AEMC Instruments.

If you cannot connect the PEL 105 to a computer:

General Checks:

1. Ensure the PEL 105 is powered ON.

2. Ensure DataView PEL Control Panel software is installed correctly on the computer.

3. Try a different connection port on the computer (e.g., different USB port).

4. Restart both the PEL 105 and the computer.

For USB Connection (§ 6.3.1):

1. Check the USB cable for damage; try a different USB cable.

2. Ensure USB drivers for the PEL 105 are installed correctly on the computer. You might need to reinstall them.

For Bluetooth Connection (§ 6.3.2):

1. Ensure Bluetooth is enabled on both the PEL 105 (Bluetooth LED lit) and the computer.

2. Ensure the PEL 105 is within Bluetooth range of the computer (typically around 10 meters/30 feet, can be less with obstructions).

3. Try re-pairing the PEL 105 with the computer.

4. Check for Bluetooth interference from other devices.

For Wi-Fi Connection (§ 6.3.3, § 6.3.5):

1. Ensure Wi-Fi is enabled on the PEL 105 (Wi-Fi LED lit).

2. If connecting to a Wi-Fi network, verify SSID and password are correct on the PEL 105.

3. If using Wi-Fi Direct, ensure the computer is connected to the PEL’s Wi-Fi network.

4. Check IP address settings; ensure they are compatible or DHCP is working correctly.

5. Firewall or antivirus software on the computer might be blocking the connection. Temporarily disable them for testing or configure exceptions.

For Ethernet Connection (§ 6.3.4, § 6.3.5):

1. Check the Ethernet cable and connections.

2. Verify IP address configuration on both the PEL 105 and the computer. They must be on the same subnet if using static IPs, or both set to DHCP.

3. Ping the PEL 105’s IP address from the computer to check network connectivity.

4. Firewall settings might be blocking the connection.

If all else fails, contact AEMC Instruments for support.

If you cannot turn OFF the PEL 105 instrument using the Power button (①):

1. Check Power Source (see § 3.3.2 of the PDF):

The instrument cannot be turned OFF via the Power button (①) while it is running on external AC power (AC adapter plugged in) or phase voltage power (Power button (①) glowing green).

If on AC adapter power: Unplug the AC power adapter first. Then press and hold the Power button (①) for two seconds until all LEDs light up simultaneously, then release.

If on phase voltage power: Disconnect the voltage terminal leads from the instrument first. Then press and hold the Power button (①) for two seconds until all LEDs light up simultaneously, then release.

2. Recording in Progress: While not explicitly stated as preventing turn-off, it’s good practice to stop any active recording before attempting to power down.

3. Button Malfunction: If the instrument is on battery power only, and pressing and holding the Power button (①) for two seconds does not turn it off, the button itself might be malfunctioning. In this case, you might have to wait for the battery to discharge or contact AEMC for service.

4. Instrument Freeze: If the instrument is unresponsive (frozen), and the above steps don’t work, you may need to remove all power sources (AC adapter, phase power connections, and then if possible, and if it’s a last resort and you are comfortable, disconnecting the internal battery, though this is generally not user-serviceable and could void warranty). It is best to contact AEMC Instruments support before attempting internal battery disconnection.

The PEL 105 can be mounted on a pole using the optional Pole Mounting Kit (Cat. #2137.82). The kit typically includes brackets and straps.

General Steps for Pole Mounting (refer to the specific instructions included with the Pole Mounting Kit):

1. Attach Brackets to PEL 105: Secure the mounting brackets from the kit to the designated mounting points on the back or sides of the PEL 105 housing using the provided hardware.

2. Position on Pole: Place the PEL 105 with attached brackets against the pole at the desired height and orientation. Ensure the instrument’s display and connection panel are accessible if needed.

3. Secure with Straps:

Feed the mounting straps (often metal bands or heavy-duty weather-resistant straps) through the slots or openings in the pole mounting brackets.

Wrap the straps around the pole.

Tighten the straps securely using the tensioning mechanism provided with the straps (e.g., screw mechanism, buckle). Ensure the PEL 105 is firmly attached to the pole and cannot move or slip.

4. Cable Management: Route any connection cables (power, voltage leads, current probe cables) neatly and secure them to prevent strain or damage. Ensure water cannot run along cables into connection points if possible (use drip loops).

5. Final Check: Double-check that the instrument is secure and stable on the pole.

Always ensure that the mounting is done safely, especially if working at heights, and that the chosen pole can support the weight of the instrument and withstand environmental conditions.

Recording sessions are configured through the PEL Control Panel. This provides options such as selecting which data to include, the demand (aggregation) period, and recording schedule. You can also change the instrument’s date and time if required. After a recording session, you can add information like session name, operator, and location.

Typically, recording sessions are started, stopped, and scheduled through the PEL Control Panel. However, you can also start and stop a recording session on the instrument itself. The aggregation period for a recording can also be set.

Recording sessions are stored on the instrument’s SD card.

The memory required for a recording session primarily depends upon the duration of the recording and the storage period. Recording rates for the different types of session data are as follows:

200ms trends: 92MB per day

1-second harmonics: 91MB per day.

1-second trends: 36MB per day.

Aggregated trend: 1.7MB per day for 1 minute periods. For longer periods, this rate is divided by the period in minutes. For example, for an aggregation period of 10 minutes, the rate will be 0.17MB per day; for 15 minute periods this is 0.113MB per day, and so on.

Aggregated harmonics: 1.6MB per day for 1 minute periods. (For longer periods, use the same formula described above for aggregated trend data.)

The recommended maximum recording times for a single session on an instrument are:

21 days when recording 200-ms trends and 1-minute aggregated data (trend and harmonics).

One month when recording 1-minute aggregated data, 1-second trends, and 1-second harmonics.

15 weeks when recording 1-minute aggregated data and 1-second trend data but not harmonics.

Three years when recording only 1 minute aggregated data (including aggregated harmonics).

Multiple years when recording only 15-minute aggregated data (without aggregated harmonics).

Other recommendations include:

Do not store more than 32 recording sessions on the SD card.

For recordings with harmonics or with a duration longer than one week, use class 4 or higher SDHC cards.

Avoid downloading large sessions via Bluetooth, because this may require many hours to finish. If Bluetooth is the only communication method available, you can reduce the amount of data to be downloaded by selectively excluding 200ms trends, 1 second trends, and harmonics from the download. Doing so reduces the data downloaded from a 30 day recording with 15-minute aggregation to 3.4MB. (You can choose which recorded data to include/exclude in the download via the PEL Control Panel.)

Before starting a recording, ensure that the instrument is not currently locked (the word LOCK appears on the screen in Configuration mode). The instrument cannot begin a recording when it is locked. The instrument is locked when:

Being configured via the PEL Control Panel.

Disabled through an option in the PEL Control Panel.

A recording session is already in progress. Note that in this case the button remains active so you can stop the recording. However, you cannot start a new recording if one is in progress.

If any of these situations is in effect, take appropriate action as necessary to unlock the instrument. Then check the SD card LED.

The SD card LED indicates the status of the SD card:

If the LED is green, the SD card is ready to store recordings.

If the LED glows steady red, ensure that:

The SD card is installed. If not, consult § 2.7.

The write-protect sliding tab on the card is in the “unlock” position (towards the metal contacts).

The SD card is formatted. Formatting can be performed either through the PEL Control Panel, or through a Windows command on your computer.

Note that the LED briefly blinks red when the card is initializing.

If the LED blinks alternately red and green, the SD card is full. Download any data you want to save to your computer, then erase the content of the card through the PEL Control Panel.

When the SD card LED indicates the SD card is ready, you can begin recording. To record through the instrument user interface, do the following:

1. Press and hold the record button down until the REC LED lights. Then release the button.

2. The REC LED should now blink twice every five seconds, indicating a recording is in progress.

3. To stop a recording, press and hold the record button down until the REC LED lights up, then release the button.

Instrument maintenance tasks include:

Erasing and upgrading the SD card

Upgrading to the latest firmware revision

Maintaining the batteries

Cleaning the instrument

When the SD card LED either (1) blinks alternately red and green, or (2) blinks green once per second, the SD card is either full or does not have enough remaining space. In either case, you must erase the SD card via an option in the PEL Control Panel. NOTE: Erasing the SD card deletes all records. Download any sessions you want to save first.

You can replace the 8GB SD card with one up to 32GB. To do this:

1. Remove the existing SD card from the instrument by pressing down and then releasing it. The card will pop up.

2. Check the replacement card to ensure its write-protect sliding tab is in the “unlock” position (towards the metal contacts).

3. Insert the SD card into the slot, with the metal contacts facing towards the top of the card.

4. Press the SD card into the slot until it clicks in place.

5. If necessary, format the card by connecting the instrument to a computer running the PEL Control Panel and selecting the Format SD Card option.

When the new card is ready for storing recordings, the SD LED glows steady green.

It is recommended to check for firmware upgrades regularly. The easiest way is from the PEL Control Panel: Help menu > Update. This automatically checks for the latest version.

Alternatively, to check the firmware revision and download a newer version:

1. Connect the instrument to your computer with the USB cable, and ensure the instrument is powered ON. (A USB connection is required for firmware updates.)

2. From the computer, open the AEMC Instruments web site (http://www.aemc.com) and click the link labeled Software and Firmware Updates.

3. In the Firmware Downloads section, find the entry for PEL 105 firmware. Compare the revision number and release date with the one on your instrument (viewable in Information mode > Firmware screen). If the website version is more recent, click the PEL 105 firmware link.

4. The PEL 105 Firmware page appears. Download the latest version in .exe or .zip format. (If .zip, you may need to extract the .exe file). Click Save.

5. After the file is downloaded, open and run it. (e.g., for .exe, click Run; for .zip, open and double-click PEL_Firmware.exe, click Run if security warning appears).

6. The Flash Upgrade Utility opens. Select the language from the drop-down list and click Next.

7. The next screen enables you to select the instrument. If it does not appear, ensure it is powered ON and connected via USB, then click Refresh. When the instrument’s name appears, select it and click Next.

8. Click the Program button to initiate the update. A status bar will track progress.

9. When the update is complete, a message appears in the Flash Upgrade Utility screen.

The instrument has a NiMH battery providing approximately one hour of power. If fully discharged after prolonged storage, it needs about 5 hours to charge.

To make the best possible use of your battery and extend its life:

Only charge the battery at temperatures between -20° and 55°C (-4° and 140°F).

Comply with the instrument usage and storage conditions defined in its manual.

Note: You cannot change the battery. This must be done at an authorized AEMC Service Center.

The instrument should be cleaned periodically. This keeps the LCD clear and prevents dirt/grease buildup.

CAUTION! Risk of Electric Shock. Before cleaning, disconnect all input(s) to prevent possible electric shock.

The body of the instrument should be cleaned with a damp and soapy cloth. Do not submerge the instrument in water. Do not use solvent.

The most common cause is a completely discharged battery. Connect the instrument to an external power source (external AC power or phase power). The instrument should immediately turn ON, and the Battery LED should glow yellow and blink, indicating the battery is recovering from a full discharge.

If the instrument does not turn ON when connected to external power, contact AEMC Technical Support.

If the instrument has been stored in a cold and damp environment, condensation may form inside, shorting internal circuitry. In this case, turn OFF the instrument and place it in a warm, dry environment for several hours. Then turn the instrument ON and try navigating through the screen interface to determine if it has been restored to normal functionality.

If configuration options appear disabled or function unexpectedly (e.g., “LOCK” appears on LCD in Configuration mode), the instrument might be locked. This occurs when being configured via PEL Control Panel or if locked through a PEL Control Panel option.

To return local control: Ensure the “Lock out the Control button on the instrument front panel” option in the PEL Control Panel is unchecked. Then disconnect from PEL Control Panel. If still locked, check if a recording is in progress (REC LED blinks twice every five seconds). Either stop the recording or wait for it to complete.

If some configuration screens are active while others are not, you may have the wrong hookup type selected. Enter Information mode and ensure the appropriate hookup type is selected.

If a recording doesn’t start (via button press or PEL Control Panel):

Check if a recording is already in progress (REC LED blinks twice per second). Wait for it to finish or stop it.

Check the SD card: Ensure it’s installed, operational, and has sufficient space. If SD LED is red: write-protected, not installed, or not recognized. If SD LED blinks red/green: it’s full. If SD LED blinks green once/second: not enough space for the attempted recording.

Check start/end times/dates: Incorrect configuration (e.g., stop date/time already passed) can prevent starting. Ensure they are configured properly.

A likely cause is that the SD card memory has become full. When this happens, the SD LED glows red. Download any data you want to save, then erase the contents of the SD card through the PEL Control Panel.

If connecting via Wi-Fi or Bluetooth: Ensure the communication protocol is enabled. Check the appropriate LED ())) for Wi-Fi, > for Bluetooth). If OFF, enable it as instructed in § 3 of the manual.

If the Bluetooth LED is blinking, the instrument is actively communicating. Only one Bluetooth connection at a time is supported; ensure no other Bluetooth connection is active.

If attempting to connect via USB or point-to-point Ethernet: Ensure the cable is securely connected to both instrument and computer. If connections are secure, close PEL Control Panel, disconnect cable, wait a few seconds, then reconnect. This resets the connection.

Also check Communication settings in the PEL Control Panel, as explained in its Help system.

If attempting to connect via Bluetooth and the PEL 105 doesn’t appear as available in PEL Control Panel: The instrument may not be paired with the computer. Consult your computer’s documentation for pairing Bluetooth devices.

The Power button is disabled if a recording is active or pending. Also, you cannot turn OFF the instrument if it is operating on external AC or phase power. Disconnect the power source, hold down the Power button until all the instrument’s LEDs light up, then release the button to turn OFF the instrument.

The sampling period is calculated every second and varies according to the line frequency (50Hz, 60Hz, or 400Hz).

50Hz:

42.5 to 57.5Hz (50Hz ±15%): sampling period is locked to the main frequency. There are 128 samples available for each main cycle.

Outside 42.5 to 57.5Hz: sampling period is 128 x 50Hz.

60Hz:

51 to 69Hz (60Hz ±15%): sampling period is locked to main frequency. 128 samples are available for each main cycle.

Outside 51 to 69Hz: sampling period is 128 x 60Hz.

400Hz:

340 to 460Hz (400Hz ±15%): sampling period is locked to main frequency. For each main cycle, 16 samples are available.

Outside 340 to 460Hz: sampling period is 16 x 400Hz.

Note that DC is not a frequency parameter for sampling. A pure DC measured signal is considered to be outside the frequency ranges. In this case sampling frequency is 6.4kHz (50/400Hz) or 7.68kHz (60Hz). By default, sampling frequency is locked on V1. If V1 is missing, the instrument attempts to lock sampling frequency V2, then V3, I1, I2, and I3.

Every second, the instrument determines the phase sequence. If the phase sequence does not meet the criteria listed in the tables (see A.2.1, A.2.2, A.2.3 in the manual), the red Phase Sequence LED blinks, and the Phase Sequence icon appears on the LCD.

To ensure proper phase sequence, the current phase sequence, voltage phase sequence, and current vs voltage phase sequence for that hookup must all be correct. Note that:

Phase sequence for voltage channels is only displayed when voltages are displayed on the LCD.

Phase sequence for current channels only is displayed when currents are displayed.

Phase sequence for voltage and current channels is displayed when the other screens are displayed.

Load or source is set by the PEL Control Panel.

In some hookups (such as DC) the phase sequence does not always apply.

The following tables from the manual list measurement ranges for correct phase sequences:

Current Phase Sequence (Table A.2.1)

Voltage Phase Sequence (Table A.2.2)

Current vs Voltage Phase Sequence (Table A.2.3)

Accessory brackets (Cat. #2137.81) enable you to mount the Model PEL 105 on a utility pole or similar structure. To mount the instrument:

1. Turn the instrument OFF and detach all leads and other connections. Slide the brackets onto the bottom of the instrument.

2. Attach the bracket by inserting the four connecting pins into the holes in the instrument case.

3. Insert the four clips into the holes in the pins.

4. Run two straps (not included) through the slots in the brackets. These slots are 25.4 x 4mm (1 x 0.157″).

5. Position the instrument on the pole, and attach it by fastening the straps.
