4.5 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
•))) CAP
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
4.6 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 rotary switch to the
Ω
•))) CAP 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 0.4 V to 0.7 V.
Reverse voltage will indicate “OL”. Shorted
devices will indicate near 0mV and an open
device will indicate “OL” in both polarities.
For Continuity tests, if the resistance is < 40
Ω
, a tone will sound.
