Hi,
If there is larger error, please refer to below calibration. You need an adjustable power supply and electronic load.
The adjustable power supply voltage is adjusted to 12V, and the current is 11A.
Click the up button to move the cursor to the NCP position. then hold the OK button (the middle button) to enter the calibration interface, release the OK button after entering the calibration interface.
Positive current calibration: 1.Click OK to switch to the +(0-100A) positive current calibration interface.
2. Turn on the electronic load and adjust the current reading of the wireless meter and the current of the electronic load are both 8A;
Negative current calibration:1. Click OK to switch to the —000A negative current calibration interface, turn off the electronic load current (others remain unchanged), let the negative wire of the adjustable power supply pass through the Hall in reverse, turn on the electronic load current again, then adjust the current reading of wireless meter and the electronic load current are both 8A. After adjustment, hold the OK button exit the calibration interface, then current calibration is completed.
Best regards.
