Measuring Capacitance
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Plug black test lead into the COM input jack.
3. Plug red test lead into V/
4. Set the rotary switch to the
5. Remove the capacitor from the circuit and discharge it.
6. Connect test leads to the capacitor to be measured.
7. Read the capacitor value on the LCD.
Optional Modes
•
Instrument set-up:
FUNC.
All capacitance measurements are to be made on de-energized
circuits with all capacitors discharged only. Failure to de-energize
and discharge capacitors prior to measuring them could result in
instrument damage and/or personal injury. Make sure the temper-
ature probe is NOT plugged in during this test.
Observe polarity on polarity sensitive capacitors.
