DC/AC Voltage Measurements
1. Insert the black test lead into the negative COM terminal
and the red test lead into the positive V terminal.
2. Set the function switch to the V position.
3. Select AC or DC with the MODE button.
4. Connect the test leads in parallel with the circuit under test.
5. Read the voltage measurement on the LCD display.
Resistance and Continuity Measurements
1. Insert the black test lead into the negative COM terminal
and the red test lead into the positive terminal.
2. Set the function switch to the •))) Ω position.
3. Use the multifunction MODE button to select resistance.
4. Touch the test probe tips across the circuit or component
under test. It is best to disconnect one side of the device under test
so the rest of the circuit will not interfere with the resistance reading.
5. For Resistance tests, read the resistance on the LCD display.
6. For Continuity tests, if the resistance is < 150Ω, a tone will sound.
Diode Measurements
1. Insert the black test lead banana plug into the negative
COM jack and the red test lead banana plug into the
positive diode jack.
2. Turn the rotary switch to the •))) position.
3. Press the MODE button until “ “ appears in the display.
4. Touch the test probes to the diode under test.
Forward voltage will indicate 0.4V to 0.7V.
Reverse voltage will indicate “OL”.
Shorted devices will indicate near 0mV and an open device
will indicate “OL” in both polarities.
