I made a mistake calibrating the current to 3 amps during my first try. I am now trying to calibrate it with 4 amps and it will not go above 3 amps with applying the offsets.

Hello Marc，

Thanks for writing in.

Is this item? 200219?

Below is the calibration steps. Did you operate it like that?

A DC adjustable  power supply, multimeter, load

Charging / discharging current calibration:
1. Hook it up according to the charging/ discharging wiring diagram.
2. Set the power supply as above 12V, then hold the OK button and power the meter simultaneously. Hold on OK for 3 seconds and then release. It will come to parameter setting;
3. Please move yellow cursor to “Mode” and short press OK button, then move the yellow cursor to “+4.A”(It is “-4A” in discharging mode). In that case, please make sure the actual load current is over 1.00A. Next, please press up or down button to adjust the current value of meter until it is the same as actual load current. After that, press OK, move yellow cursor to ”Save” and save the calibration.

Best regards.
