DC & AC Voltage Measurement
1. Insert the RED rest probe into the input terminal ‘V’ and the black probe into the ‘COM’ terminal.
2. Turn the rotary switch to the voltage ( ) setting. Th meter is factory set to DC voltage measurement mode. Press the SEL/V.F.C button
to select the desired AC or DC voltage measurement mode. In the AC measurement mode, the V.F.C (Variable Frequency Voltage)
measurement mode can be activated by pressing down the SEL/V.F.C button for 2 seconds. To exit the V.F.C mode, press the button
again.
3. To measure the voltage, connect the test leads in parallel to the circuit or device under test. The measured voltage value will show on
the LCD screen. For DC voltages, the polarity of the voltage will be relative to the position of the RED probe in the circuit. When
measuring AC voltage, press HZ button to display the voltage frequency value.
Note If the meter shows small voltage values on the screen without there being any circuit under test, reset the display to zero short-
circuiting the meter probes.
Warning Do not measure any voltages higher than DC 600V or AC 600V RMS to prevent electric shock and/or damage to the meter.
AC and DC Current Measurement
1. Cut off the power of the circuit under test to discharge all high voltage capacitors on the circuit under test.
2. Turn the rotary switch to the desired current measurement setting. Use the SEL button to select DC or AC measurement mode.
3. Insert the BLACK test lead into the "COM" input terminal and the RED test lead into the corresponding current input terminal.
4. Connect the test probes in series with the test load whose current is to be measured.
5. Tum on the power to the circuit under test to get the current readings to show on the display.
6. Cut off the power of the circuit under test. Discharge all high-voltage capacitors. Remove the meter probes and restore the circuit to
its original condition.
Note If the display only shows "OL", it means that the current input exceeds the measurement range of the circuit.
Use the correct input terminal and settings for current measurement. If the probe is inserted into the current input terminal , do
not connect the probe to any circuit in parallel mode.
If the fuse blows during measurement, please replace it with a fuse of the same rating, before carrying out any measurements.
Warning Do not attempt current measurements on a circuit where open circuit voltage exceeds 250V.
When measuring a large current between 5-10A, ensure the power-on time doesn’t exceed 10 second as it may result in incorrect
test data due to the heat generated by high current.
Resistance Measurement
1. Turn the rotary switch to the resistance ( ) setting. The symbol “0L” on the display indicates open circuit .i.e., no resistance is
connected.
2. Ensure the black test lead is inserted into the "COM" terminal and the red test lead into the "V" terminal.
3. If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors before measurement.
4. Use the probe tips to measure the resistance of the circuit under test.
5. Read the resistance value on Digital Display.
Warning To prevent damage to the meter or the device under test, disconnect the power supply of the circuit under test and fully
discharge all high-voltage capacitors before measuring the resistance.
Capacitance Measurement
1. Turn the rotary switch to the ( ) setting. Press the SEL key to switch to capacitance measurement mode.
2. Insert the black test lead into the "COM" terminal and the red test lead into the "V" terminal.
3. Use the probe tips to measure the capacitance of the circuit under test. Read the capacitance value on Digital Display.
