Calibration and Zero Adjustment
Periodic adjustment of the meter is possible. With the meter turned off (power removed), apply a short (jumper) between test points A and B. With the jumper in place, apply power to the meter which will be automatically calibrated to zero. Remove the jumper placed between A and B.
The current display can also be adjusted through the trim pot R7. Simply apply a known current across the meter of approximately 25A (mid-way between the maximum value). Adjust R7 until the meter displays the correct current reading. Digital Panel Meter - Voltage and Current - Calibration and Zero Adjustment
