Measurement of direct current (DC) voltage
1. Set the rotary switch knob to the position.
2. Select the measuring range. In case you do not know the voltage range in advance, set
the highest range and reduce it gradually after every measurement.
3. Attach the measuring pins to a device or circuit, where you measure the DC voltage.
4. Turn on the power supply of the device that you measure. The display displays the
voltage and polarity relative to the red measuring tip.
Note:
To avoid electric shock or damage of the measuring device do not connect voltages higher
than 300 V.
Measurement of alternating current (AC) voltage
1. Set the rotary switch knob to the position.
2. Select the measuring range - In case you do not know the voltage range in advance,
set the highest range and reduce it gradually after every measurement.
3. Attach the measuring pins to a device or circuit, where you measure the AC voltage.
