4.2.5.Voltage / current displaytest and measurement

CUR CAL / VOLT CAL potentiometers

These potentiometers are used to calibrate the digital display meter for current and voltage measurements. As the two potentiometers affect each other, current calibration must be performed before voltage calibration.
