RESISTANCE MEASUREMENTS

WARNING: To avoid electric shock, disconnect power to the unit under test and

discharge all capacitors before taking any resistance measurements. Remove the

batteries and unplug the line cords.

1.

Set the function switch to the Ω position.

2.

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

Insert the red test lead banana plug into the positive

Ω jack.

3.

Press the MODE button to indicate “

Ω" on the display.

4.

Touch the test probe tips across the circuit or part under test.

5.

Read the resistance in the display.

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

Ω 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 150

Ω, 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 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.
