Resistance Measurements; Continuity Check - Circuit-test DMR-6700 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
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. 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.
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 Ω
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 "
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 100Ω, the
audible signal will sound. If the circuit is open, the display will indicate
"OL".
