SISCO SISCO-ETCR6900 (01) PDF Document

The SISCO SISCO-ETCR6900 is designed and manufactured for field testing of AC large current. It can also be used as a common multimeter to measure AC voltage, DC voltage, resistor, and continuity testing. It is especially suitable for flat cable dense places, current test of transformer grounding cores, thick wires and cables, and industrial environments with serious signal distortion.

The SISCO SISCO-ETCR6900 uses a Rogowski Coil flexible current clamp sensor. It adopts advanced Rogowski Coil technology, which is a loop coil uniformly wound on non-ferromagnetic materials with no hysteresis effect, almost zero phase error, no magnetic saturation, high linearity, and strong anti-interference ability.

To start the meter, press the POWER key. The LCD will display and the device will enter measurement mode. To shut down the meter, press the POWER key again. Additionally, the meter will automatically shut down after 10 minutes of inactivity to reduce battery consumption.

Read the instruction manual in detail and comply with all safety regulations and cautions listed in the PDF.

Pay special attention to safety under all circumstances when using this meter.

Do not connect the meter to a computer when testing voltage, as the communication interface is non-isolated and may cause burns or electric shock.

Pull out the voltage test line before connecting the communication data line to a computer.

Keep the clamp jaw clean and maintain it regularly.

Do not store the meter in high temperature, high humidity, dewy places, or under direct sunlight for long periods.

Take out the battery if the tester will not be used for a long time.

Use, disassembly, and maintenance should be performed by authorized personnel.

Step 1. Start up the meter and enter measurement mode.

Step 2. Rotate the lock catch toward the OPEN direction, unscrew the flexible coil lock catch, and clamp the measured wire with the flexible coil.

Step 3. Rotate the lock catch toward the CLOSE direction to lock the flexible coil.

Step 4. Observe the reading value. The tested wire should be in the central position of the flexible coil as far as possible (near point A in the diagram) for the highest accuracy.

If the meter displays the “OL” symbol, it indicates that the measured value exceeds the upper limit range of the meter.

When the measured current is small, resolution can be improved by repeatedly wrapping the flexible coil around the measured wire. For example, if you wrap the coil 3 times and the meter shows 30A, the actual current is 10A (display value divided by the number of windings).

Press the MODE key to switch between three different measurement modes: Current/AC voltage, Current/DC voltage, and Current/resistor.

Step 1. Start up the meter.

Step 2. Press the MODE key to switch to AC V (AC voltage mode) or DC V (DC voltage mode).

Step 3. Connect the test line to the meter, and the display will show the voltage value.

Step 1. Start up the meter.

Step 2. Press the MODE key to switch to the RES resistance gear.

Step 3. Connect the test line to the meter, and it will display the resistance value.

Step 1. Start up the meter.

Step 2. Press the MODE key to switch to the RES resistance gear.

Step 3. Press the SET key to turn on the continuity testing function. A symbol will appear to indicate it is on.

Step 4. Connect to the test line. When the tested resistance value is smaller than 20 ohms, the buzzer will ring to alert you.

After starting the meter, press the key with the sun icon to control the backlight. It is suitable for dark sites, and the backlight is open by default upon startup.

Press the HOLD key to hold the current display data; the LCD will show the “HOLD” symbol. Press the HOLD key again to cancel the hold. The meter will automatically number and save the data when held. It can store up to 600 groups of data.

In measurement mode, press the MEM key to enter data query mode. The display will show the “READ” symbol. Press the HOLD key to increase the query number or press the MEM key to decrease it. Press the MODE key to return to measurement mode.

Step 1. In data query mode, press the SET key to enter the delete option.

Step 2. Press the MODE key to switch the cursor between “YES” and “NO”.

Step 3. Select “YES” to confirm deletion and press the SET key to confirm.

Connect the meter to the computer using the standard USB communication line. Use the provided system software to read, query, save, or print historical data. Data can be saved in Txt or Excel formats. Ensure the voltage test lines are removed from the meter before connecting the USB cable to prevent damage.

Working Environment: -10 degrees Celsius to 40 degrees Celsius; below 80% relative humidity.

Storage Environment: -10 degrees Celsius to 60 degrees Celsius; below 70% relative humidity.

Step 1. When battery voltage drops to 4.8V and the low battery symbol is displayed, prepare for replacement.

Step 2. Press the POWER key to shut down the meter.

Step 3. Open the battery cover and replace the old batteries with four new LR03 Alkaline dry cells, paying close attention to polarity.

Step 4. Replace the battery cover and press the POWER key to confirm the replacement was successful.

According to the safety warnings in the PDF, the meter cannot be used to measure lines where the voltage exceeds 1000V, as it would cause a danger of electric shock or injury. For circuit loops specifically, it should not be used to measure over 600V.

The insulation resistance is 100M ohms or more at 1000V.

After voltage is measured, the test line should be removed from the tested wire first, and then pulled out from the meter to avoid electric shock.

The measured conductor should be in the center of the coil. Error increases if the conductor is near the opening/closing point (area C) or the outer edges of the coil.

The meter complies with IEC1010-1, IEC1010-2-032, Pollution Degree 2, CAT VI (1000V), and IEC61326 (EMC standard).

With the backlight on, the working current is 80mA. With the backlight off, it is 40mA.

Yes, the meter automatically detects and handles frequencies of 50Hz and 60Hz.

The dimensions (Length x Width x Height) are 200mm x 370mm x 35mm.

The meter cannot perform tests if the battery cover plate is not covered properly. Attempting to do so is extremely dangerous.

Clean the clamp head and maintain the meter after each test to ensure its longevity and performance.
