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 green Ω 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 MODE button to indicate“ "and “Ω” 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 35, the audible signal will

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

DIODE TEST

1. Set the function switch to the green Ω position.

2. Insert the black test lead banana plug into the negative COM

jack and the red test lead banana plug into the positive V jack.

3. Press the MODE button to indicate “ “ and “V” on the display.

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.
