Resistance 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. 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.
4. For Resistance tests, read the resistance on the LCD display.
Diode and Continuity 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 function 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 indi-
cate 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.
5. Press
MODE
button to display .
6. For Continuity tests, if resistance is < 40Ω, tone will sound.
