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 250 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.
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.
To avoid electric shock or damage of the measuring device do not connect voltages higher than 250 V.
Measurement of DC current
1. Set the rotary switch knob to the position.
2. Select the measuring range - In case you do not know the current 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.
4. Turn on the power supply of the device that you measure. The display displays the current value and polarity relative
to the red measuring tip.
Resistance Measurements
1. Set the rotary switch knob to the
position.
2. Select the measuring range - In case you do not know the value of the measured resistance in advance, set the
highest range and reduce it gradually after every measurement.
3. Attach the measuring pins to a measured device.
4. The measured value is displayed on the display.
Note:
If you measure a value higher than 1MΩ, it is normal that the measured value of the resistor stabilizes after a few seconds. If
the circuit is not closed, the display will show “1”.
Disconnect circuit from its power source and discharge high-voltage capacitors before measurement.
Diode Test
This mode can be used for diodes, transistors and other semiconductor components inspection.
1. Set the rotary switch knob to the
position.
2. Attach the red measuring pin to the anode of a measured diode and the black measuring pin to the cathode. The
display shows the voltage of the diode in the forward direction. The display shows “1” if the connection is bad.
To avoid damage of the multimeter or the measured devices, disconnect circuit from its power source and discharge
all high-voltage capacitors before the diode measurement. Disconnect the measured device or circuit from the measuring
leads after measurement.
Battery Test
1. Set the rotary switch knob to the position for battery testing 1.5V or 9V.
2. Attach the measuring pins to the battery with the red pin connected to the positive pole and the black tip to the
negative pole of the battery.
3. The measured value is displayed on the display.
Note:
Disconnect the test pins from the battery after measurement.
Generator of a rectangular output signal (voltage)
1. Set the rotary switch knob to the
position.
2. Attach the measuring pins to the tested device.
3. The measured value is displayed on the display.
