6.5. 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 CAP
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 30Ω,
the audible signal will sound. If the circuit is open,
the display will indicate "
OL ".
6.4. 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 CAP
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. 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 on the display.
