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