h. Measuring Capacitance
FUNCTION
All capacitance measurements are to be made on de-
energized circuit with all capacitors
Discharged only. Failure to de-energize and discharge
capacitors before attempting to measure them could result
in instrument damage and/or personal injury.
Measurement Procedure:
1. Disconnect power to circuit to be measured.
2. Remove capacitor from the circuit and discharge it.
3. Plug black test lead into the
4. Plug the red test lead into the
5. Set the rotary switch to the
6. Connect test leads to capacitor to be measured.
7. Read the capacitor value on the LCD.
