4. Touch the test probes to the diode under test. Forward

voltage will typically indicate 0.400 to 0.700V. Reverse
voltage will indicate “OL”. Shorted devices will indicate
near 0V and an open device will indicate “OL” in both
polarities.

Note:
DO NOT CONNECT THE TEST LEADS TO ANY PART OR
CIRCUIT WITH VOLTAGE PRESENT. DOING SO MAY
DAMAGE THE METER OR RESULT IN USER INJURY.

Audible Continuity Test

Set the Function Switch to the

position.

2. Insert the black test lead into the COM jack and the red

test lead into the V/Hz%/Ω/Cap/Temp jack.

3. Touch the test probe tips to the circuit you wish to check.

4. If the resistance is less than approximately 50Ω, the

beeper will sound. If the circuit is open, the display will
indicate “OL”.

AC Voltage Sensor

1. Set the Function Switch to any position other than OFF.

2. Holding the meter, position its top near wires suspected

as having ‘live’ AC voltage.

3. If the wires have 50 to 1000V AC (60Hz) the AC Voltage

LED will light.
