the prompt.
200mA: Input 20mA, after the measured value is stable press Enter to confirm. Then
according to the prompt, enter 200mA, then set the true value, 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: according to the prompt, enter the proper value, 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: Input 200mA, 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 ACI is complete, and the program will write the above calibration data
into FLASH.
5. Resistance calibration (2-wire/4-wire all need calibration) (the following steps
serve only as reference; the value entered should be in accordance with the prompt
on the screen)
Ent
er the resistance calibration interface, the default range for calibration is 200Ω
200Ω: short circuit for the input terminals, after the measured value is stable press
Enter to confirm. Then according to the prompt, enter 200Ω, then set the true value,
after the measured value is stable press Enter to confirm. Then the calibration for
200Ωrange is completed, and the program will automatically switch to the 2kΩ level,
and change the prompt.
2kΩ: short circuit for the input terminals, after the measured value is stable press
Enter to confirm. Then according to the prompt, enter 2kΩ, then set the true value,
after the measured value is stable press Enter to confirm. Then the calibration for
2kΩrange is completed, and the program will automatically switch to the 20kΩ level,
and change the prompt.
20kΩ: short circuit for the input terminals, after the measured value is stable press
