DANGER:

Never bring the probe close to a flammable gas atmosphere. The heated sensor may cause a fire or explosion.

Never touch the sensor. The sensor is heated during operation and touching it may cause burns or damage the sensor itself.

Do not disassemble or heat the batteries, or put them into a fire. This may cause burns and the batteries may burst.

If abnormal noises, smells or smoke occur, or if liquid enters the instrument, turn off the instrument immediately, and remove the batteries or pull out the plug. There is a possibility of malfunction, electric shock, and/or fire. Contact your local distributor for repair.

CAUTION:

Always unplug the instrument from the electrical outlet when the instrument is not in use. Failure to do so may cause an electrical shock, fire or circuit damage.

Do not use the instrument in a water vapor atmosphere. Condensed steam on the sensor will change the heat dissipation rate, resulting in inaccurate measurements and may cause damage.

This instrument is designed for use in a clean air stream without any dust or foreign materials, which can cause damage or impede accurate measurements.

Do not apply force to the sensor. If the sensor is deformed, its accuracy may be affected.

When measuring, ensure that the direction mark is facing into the airflow. Otherwise, the measurement may be inaccurate, as some sensors (uni-directional probes) have a specific directivity.

Do not use or leave the instrument in a high temperature, high humidity or dusty environment, or under direct sunlight for a prolonged period.

Do not subject the instrument or the probe to strong impacts. Dropping the unit or placing heavy objects on it may cause damage.

Never disassemble, modify or repair the product.

Do not pick up or carry the instrument by the probe cable, as it may cause a malfunction or break the wire.

Remove the batteries from the battery compartment when storing the instrument for a long period. Do not leave exhausted batteries in the compartment. Insert batteries with the correct polarity to prevent battery leakage.

Do not wipe the instrument with a volatile solvent like thinner or benzene. Use a soft dry cloth. For persistent stains, use a cloth soaked in a neutral detergent.

Discharge any built-up static electricity from your body before touching the instrument to prevent damage to the circuit.

Regularly check the head of the probe for contamination. To clean dust, use a blow brush for cameras or rinse with water and allow it to air-dry completely. Always turn the power off before cleaning and never dry the probe with heat.

Do not move the main unit and the probe from a cold to a warm place quickly to avoid condensation, which can cause inaccurate measurements and rusting.

Do not touch the LCD screen with a sharp-pointed object or with excessive pressure.

When storing the instrument, put it in the carrying case and keep it in a place with an ambient temperature of -10 to 50°C and no condensation.

Do not dispose of the instrument as household waste. Disposal of the instrument and batteries should be in line with your local or national legislation.

Follow these steps to install the batteries:

1. On the backside of the body, press down on the battery cover.

2. Slide the cover until it stops.

3. Lift the cover away from the body.

4. Insert six (6) AA size batteries according to the indicated polarity chart. The instrument requires all six batteries to be of the same type. Do not mix different types of batteries. Note that batteries cannot be recharged by the AC adapter.

Types of batteries that can be used are:

Manganese AA size batteries

Alkaline AA size batteries

Ni-Cd AA size batteries

Ni-MH AA size batteries

5. Put the cover back on by reversing the above procedure.

Always make sure the power is turned OFF when connecting or disconnecting the probe or probe cable.

Connecting the Probe:

1. Align the connector of the probe or probe cable with the probe terminal on the body. When connecting the probe, ensure the probe number faces towards the front side of the main unit.

2. Line up the connector and the terminal and gently push until it clicks. Do not force or rotate the connector once it is connected, as this may cause serious damage.

Disconnecting the Probe:

1. Lightly lift the locking ring of the probe/probe cable.

2. Pull the probe/probe cable out vertically while holding the lock ring up. Do not rotate the connector when it is connected to the main body.

The power switch is located on the side of the instrument.

Power ON: Slide the switch to the “|” position.

Power OFF: Slide the switch to the “O” position.

When you turn the power on after connecting the probe, a test screen will be displayed for a few seconds before it switches to the Normal Mode screen. If the probe is not connected properly, a “NO PROBE!” warning will be displayed. If this happens, turn the power off and check the probe connection.

The battery level indicator on the display shows the remaining battery level. The indicator changes as the battery level decreases.

Full to Low: The indicator icon will show a decreasing number of bars.

Blinking Indicator: When the batteries need to be replaced or recharged, the indicator will start blinking. The screen may freeze if a high velocity is measured when the indicator is blinking.

Locked Status ( [X] symbol): When this symbol is displayed, all functions are locked. The current measurement will be cancelled and data will not be saved. To release the lock, turn off the power and replace the batteries.

Air Velocity:

For directional probes (MODEL 6531/6541/6561), make sure the direction mark is facing into the airflow. If unsure of the direction, slowly rotate the probe to find the maximum velocity reading.

For omnidirectional probes (MODEL 6533/6542/6543/6551/6552), be aware of their 360-degree horizontal dynamic characteristic.

Ensure both the air velocity sensor and temperature compensation sensor are evenly exposed to the airflow under the same temperature conditions.

In environments with rapid air temperature changes, wait for the reading to stabilize for at least 20 seconds before starting the measurement.

Air Temperature:

Response time is faster in higher wind speeds. Wait for the reading to become stable before measuring. The normal response time is approximately 30 seconds at 1 m/s air velocity.

When there is no airflow, the reading may be higher than the actual temperature due to heat from the air velocity sensor. It is recommended to slowly wave the probe to create approx. 0.1m/s airflow for accurate readings.

Humidity:

In atmospheres with extremely high humidity or rapid temperature changes, readings may be higher due to condensation on the sensor. If this occurs, allow the probe to dry in an environment with 40%RH or less for 24 hours.

Hold the Current Reading:

While measuring in NORMAL Mode, press the START/HOLD key to hold the current reading. The “HOLD” indicator will appear on the display. This applies to flow rate and pressure screens as well. Press START/HOLD again to release.

Hold the Maximum Value:

While measuring in NORMAL Mode, press and hold the START/HOLD key. The “HOLD” indicator will appear. As long as you keep the button pressed, the instrument will display the maximum value of each parameter (air velocity, air temperature, humidity, and pressure). When you release the button, the reading will be frozen. Press START/HOLD again to release.

In NORMAL Mode, you can change the Time Constant (TC) by pressing the up/down navigation keys. The Time Constant determines the time span of the moving average. A longer value provides more stable readings, while a shorter value is more responsive.

You can select from:

TC1: Displays the instantaneous value at every 1 second.

TC5: Displays the moving average for the past 5 seconds.

TC10: Displays the moving average for the past 10 seconds.

By default, the time constant is only effective for AIR VELOCITY and AIR FLOW measurements. To apply it to AIR TEMPERATURE, HUMIDITY, and PRESSURE as well, you must change the settings.

CALCULATION Mode automatically calculates the maximum, minimum, and mean of measured data.

Setup:

1. Press MENU and select “3. CALCULATION”, then press SET.

2. Select “1. MODE” and choose AVERAGE (displays average for sampling time) or INSTANT (takes a single measurement at the end of sampling time). Press SET.

3. Select “2. SAMPLING (TIME)” and set the duration from 1 to 999 seconds. Press SET.

4. Select “3. SAMPLING(n)” and set the number of trials from 1 to 9999. Press SET.

5. Select “4. DATA STORAGE?” and choose YES or NO. Press SET.

6. Select “5. SET TO START” and press SET. The instrument will be in READY mode.

Measurement:

1. In the READY screen, press MODE to change the applied parameters if needed (Air Velocity, Flow Rate, Pressure, etc.).

2. Press START/HOLD to start the measurement.

3. The measurement will proceed according to your settings. Press START/HOLD to stop it. If you selected YES for data storage, the data will be stored. Pressing MENU will also stop the measurement, but the data will not be saved.

4. After all trials are finished, the calculated results (MAX, AVG, MIN) will be displayed. Use the navigation keys to cycle through results for each parameter.

Clean the sensor by soaking it in water in an ultrasonic cleaner for 10 to 20 seconds. Do not soak it for too long to avoid damaging the coating. Please use only water for cleaning the probe.

CAUTION:

When cleaning, make sure the power is turned OFF.

Make sure that the sensor is dry before turning it ON.

DO NOT let the humidity sensor come into contact with water. If it gets wet, let it air dry by placing it in an environment with less than 40%RH for more than 24 hours.

NEVER USE alcohol or any other organic fluid, as it will cause permanent damage to the humidity sensor.

DO NOT place the sensor in an upward position until it is completely dry as residual water could damage the sensor.

After cleaning, you can dry the probe with cool air.

Discomfort Index (DI)

Discomfort Index is an index to show how uncomfortable it is in the summer time. The KANOMAX CLIMOMASTER 6551-21 uses the formula: DI = 0.81T + 0.01H(0.99T – 14.3) + 46.3, where T is Temperature (°C) and H is Relative Humidity (%RH).

The DI Scale is as follows:

Dew Point Temperature (DT)

This is calculated using a formula based on saturated vapor pressure.

The battery may be inserted with the wrong polarity. Turn off the power and insert the battery correctly according to the polarity markings.

The display contrast may not be set up properly. You can adjust the contrast volume switch/dial, which is located inside the battery compartment.

This indicates that the battery is low. Turn off the instrument and replace the batteries.

This message indicates that the probe is not connected. Turn off the instrument and ensure the probe is securely connected.

Yes, you can change the measurement units by following the steps on page 46 of the user manual.

This indicates that the measurement is outside the measuring range. The instrument must be used within the range stated in the specifications.

This could be due to a few reasons:

The probe or the probe cable is not connected properly. Check the connection between the probe and the probe cable.

The probe or the probe cable may be damaged. In this case, contact your local representative for repair or replacement.

The probe might not be facing into the wind. For directional probes, make sure the wind direction indicator is facing into the wind.

The device cannot measure the correct temperature with no wind (less than 0.1m/s of wind) due to heat from the sensor. For an accurate reading in still air, slowly wave the probe.

Check that the correct time constant (TC) is set. A longer time constant (e.g., TC10) will result in a slower response time.

This indicates that the duct information (shape and size) is not stored. You must register the duct information in the settings to get a flow measurement.

There are several possible causes:

The printer is not connected properly. Confirm the printer connection.

The Baud Rate might not be set properly. Check that both the instrument and printer settings match.

You may not be using the optional printer (Model DPU-S245) and printer cable (Model 6000-31).

The connection procedure may be incorrect. Connect the printer to the printer port, then turn on the instrument and then the printer.

The display is not frozen. First, press START/HOLD to hold the display. Then, press MODE to print out.

Confirm the USB connection, which is different from the printer connection.

The Baud Rate might not be set properly. Check that both the instrument and PC settings match.

Confirm you are using the correct communication command (e.g., in Hyper Terminal).

First, check the connection and confirm the polarity is correct.

Second, the HOLD function might be active. Press START/HOLD to cancel the HOLD function.

Confirm the setting for analog output and confirm the output range is correctly selected.
