after the measured value is stable press Enter to confirm. Then the calibration for
200mA range is completed, and the program will automatically switch to the 2A level,
and change the prompt.
2A: open circuit for the input terminals, after the measured value is stable press Enter
to confirm. Then according to the prompt, enter 2A, then set the true value, after the
measured value is stable press Enter to confirm. Then the calibration for 2A range is
completed, and the program will automatically switch to the 10A level, and change the
prompt.
10A: open circuit for the input terminals, after the measured value is stable press
Enter to confirm. Then according to the prompt, enter 2A, then set the true value, after
the measured value is stable press Enter to confirm, and the secondary display shows
OK. Then the calibration of DCI is complete, and the program will write the above
calibration data into FLASH.
4. AC current calibration (the following steps serve only as reference; the value
entered should be in accordance with the prompt on the screen)
Enter the calibration interface of ACI, the default range for calibration is 200uA (with
the frequency of 1kHz)
200uA: Input 20uA, after the measured value is stable press Enter to confirm. Then
according to the prompt, enter 200uA, then set the true value, after the measured
value is stable press Enter to confirm. Then the calibration for 200uA range is
completed, and the program will automatically switch to the 2mA level, and change the
prompt.
2mA: Input 200uA, after the measured value is stable press Enter to confirm. Then
according to the prompt, enter 2mA, then set the true value, after the measured value
is stable press Enter to confirm. Then the calibration for 2mA range is completed, and
the program will automatically switch to the 20mA level, and change the prompt.
20mA: Input 2mA, after the measured value is stable press Enter to confirm. Then
according to the prompt, enter 20mA, then set the true value, after the measured
value is stable press Enter to confirm. Then the calibration for 20mA range is
completed, and the program will automatically switch to the 200mA level, and change
