User Manual

Resistors Ra and Rb are ½ Watt; 0,5 % metal-foil resistors.
b) Connect module to an external DC voltage source.
c) The accuracy on all ranges expect 200 mV range should
be adjusted with a calibrated voltage of 50% of the
selected range (i. e. 100 V for 200 V range). Adjust
potentiometer for equal reading of scale.
d) Connect the voltage to be measured to terminals VIN and
GND (4). Connect DC voltages to the input terminals only.
4.2. Measuring DC current
To measure DC current, wiring measuring input (4) as per
following table:
Range Decimal-point Shunt
200 µA Short P3 1 kΩ
2 mA Short P1 100 Ω
20 mA Short P2 10 Ω
200 mA Short P3 1 Ω
2000 mA 0,1 Ω
