    Insert the CORD/IEC main test cord into the output socket (10) and the other end into input socket (11). Press the POWER key to turn on the instrument, and press and hold the combination key F + A until entering the calibration interface. Press the C key to calibrate the CORD test grounding resistance; after the calibration is completed, the resistance of the current test cord (line) will be displayed. Press the F key to exit.

Test Voltage selection
In addition to selecting the output voltage (250V/500V) of the test insulation resistance in the CLASS I/II test, you can select the working voltage (110V/230V) of the equipment to be tested according to the working voltage of the equipment under test. The setting of the working voltage (110V/230V) of the equipment to be tested will affect the leakage current test results and the out-phase detection function.

Switch to LEAKAGE, press the POWER key to select the voltage, and switch 110V/230V through ▲ and ▼ keys. Press the POWER key to confirm and exit.

CLASS I test

  • Connect the equipment to be tested to the meter with the mains test cord supplied with the appliance to the meter output socket and the other end to the power connector of the equipment to be tested.
  • Connect the Earth bond lead to the meter (Terminal 12) then connect the other end to a metal conductive part of the CLASS1 appliance (connected to the protective conductor of the equipment).

After correct connection, press the A key to start the CLASS I test. Ensure that the equipment to be tested is powered on during the test. After the test is started, the meter will light the symbol at the right hand side of the LCD screen to indicate that the CLASS I test is being performed currently. The test will be done automatically according to the following steps:

  • Grounding Test
    • Test the resistance between the conductive part of the equipment to be tested and the protected area.
    • If the measured resistance is greater than 25Ω, the buzzer and the grounding icon flash to indicate the grounding fault. After 5 seconds, exit and return to the main interface;
    • If the measured resistance is less than 25Ω, compare with the set resistance, display the resistance and “√” or “×”, and then conduct the next test.
  • Insulation Resistance Test
    • If the power switch of the equipment to be tested is off, the instrument may display LO LOAD to indicate that the equipment to be tested has an insufficient load capacity. Press the A key or turn on the power switch of the equipment to be tested to continue the insulation resistance test. Press any other key to exit and return to the main interface.
