Apply power to the circuit.

Read the current on the display. The display will indicate the

proper decimal point value.

4.6. 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.

Set the function to the Ω position.

Insert the black test lead banana plug into the negative (COM)

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

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.

Read the resistance on the display. The display will indicate the

proper decimal point value.

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 (Ω).

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

If the resistance is less than approximately 50Ω, the audible

signal will sound. The display will also show the actual resistance.

Warning: To avoid electric shock, do not test any diode that has

voltage on it.

Set the function switch to the
