WARNING
Turnoffpowertothedeviceundertestanddischargeallcapacitors.
Themeasuringcapacitanceisasfollows:
1.  Turnoffpowertothedeviceundertestanddischargeallcapacitors.
2.  Dischargeallvoltagefromthecapacitorbeforemeasuringitscapacitancevalue. 
3.  Setthecapacitancerangethatgivesthemostaccuratemeasurement reading ortoselectautorange. 
4. Connect the alligator clips to capacitor leads or insert leads of the capacitor into multimeter
measuringsocket.Alwaysobservepolaritymakingswhenmeasuringpobrizedcapacitor.
5. Read capacitance value directly from display. The measurement accuracy of capacitors can be
improved by first using the (Relative mode) to zero the and automatically subtract the residual
multimeterandtestleadcapacitance.SincetheRelativemodealsoselectsmanualranging.
6. Residual voltage charges on the capacitor, or capacitors with poor insulation resistance or poor
