Resistance Measurements; Continuity Check - Circuit-test DMR-6500 User Manual

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 and
the red test lead banana plug into the positive Ω 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.
1. Set the function switch to the
2. Insert the black lead banana plug into the negative (-) jack COM and
the red test lead banana plug into the positive (+) jack Ω.
3. Press the MODE button until the
4. Touch the test probe tips to the circuit or wire you wish to check.
5. If the resistance is less than approximately 30Ω, the audible signal will
sound. The display will also show the actual resistance.
