1.Insert the black test lead into the negative terminal and the red test lead into
the positive V terminal.
2.Set the function switch to the position.
3.Select AC or DC with the button.
4.Connect the test leads in parallel to the circuit under test.
5.Read the voltage measurement on the LCD display.
1.Insert the black test lead into the negative terminal and the red test lead into
the positive terminal.
2.Set the function switch to the position.
3.Use the multifunction 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 < 120 , a tone will sound.
1.Insert the black test lead banana plug into the negative 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.
