CONTINUITY CHECK
WARNING: To avoid electric shock, never measure continuity
on circuits or wires that have voltage on them.
1. Set the function switch to the
! position.
2. Insert the black lead banana plug
into the negative (COM) jack
Insert the red test lead banana
plug into the positive (!) jack.
3. Press the SELECT button to
indicate !!!!on the display
4. Touch the test probe tips to the
circuit or wire you wish to check.
5. If the resistance is less than
approximately 150!, the audible
signal will sound. If the circuit is
open, the display will indicate “OL”.
DIODE TEST
1. Set the function switch to the
! position
2. Insert the black test lead banana
plug into the negative COM jack
and the red test lead banana plug
into the positive diode jack.
3. Press the SELECT button to
indicate !!!!!!on the display.
4. Touch the test probes to the
diode under test. Forward voltage
will typically indicate 0.400 to
0.700mV. Reverse voltage will
indicate “OL”. Shorted devices
will indicate near 0mV. Shorted
devices will indicate near 0mV
and an open device will indicate
“OL” in both polarities.
