5. To calibrate the Capacitance function, use the PC and serial communication software to enter these
commands:
Command
cal start_capacitor
misc capacitor_finished
misc capacitor_coef
cal_param capacitor CAP_COEF
cal stop_capacitor
cal_param save
6. To calibrate the function, use the PC and serial communication software to enter these commands:
VDC
Command
cal start_dmm_vdc
adc vac_vdc r
cal_param dmm_vdc 0
0 ADC_READ
adc vac_vdc r
cal_param dmm_vdc 1 600
ADC_READ
cal stop_dmm_vdc
cal_param save
Operation / Purpose
Connect the 2 μF capacitor between L and E
Enter Capacitor calibration mode
Wait 6 seconds at least
Query whether or not the capacitor calibration
process is finished, if not finished, do this step again
Query calibrated coefficient
Write coefficient
Stop the Capacitor calibration
Save the calibration parameters
Operation / Purpose
Connect the calibrator between E and G (use VDC
function)
Enter VDC calibration mode
Calibrator outputs 0 V
Read the Voltage analog-to-digital conversion value
Write the calibration parameter 0, use read value
ADC_READ in the previous step
Calibrator outputs 600 V
Read the Voltage analog-to-digital conversion value
Write the calibration parameter 1, use read value
ADC_READ in the previous step
Stop the VDC calibration
Save the calibration parameters
Insulation Tester
