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  position.

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

(COM) jack and the red test lead banana plug into the

positive  jack.

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

test. It is best to disconnect one side of the part under test

so the rest of the circuit will not interfere with the

resistance reading.

4. Read the resistance in the display. The display will indicate

the proper decimal point, value and symbol.

CONTINUITY CHECK

WARNING: To avoid electric shock, never measure

continuity on circuits or wires that have voltage on

them.

Set the function switch to the

Insert the black lead banana plug into the negative (-)

jack (COM) and the red test lead banana plug into the

positive (+) jack ().

Press the

button until the

in the display.

Touch the test probe tips to the circuit or wire you wish

to check.

If the resistance is less than approximately 100, the

audible signal will sound. The display will also show the

actual resistance.

DIODE TEST

WARNING: To avoid electric shock, do not test any

diode that has voltage on it.

1. Set the function switch to

2. Press the

button until the

in the display.

3. Insert the black test lead banana plug into the negative (-)

jack (COM) and the red test lead banana plug into the

positive (+) jack ().

Touch the test probe tips to the diode or

semiconductor junction you wish to test. Note the meter

reading

5. Reverse the probe polarity by switching probe position.

6. The diode or junction can be evaluated as follows:

NOTE: The value indicated in the display during the diode

check is the forward voltage.

FREQUENCY MEASUREMENT
