Beforemeasuring insulation resistance, confirm that thesample is fullydischarged(particularly indielectricandcapacitancesamples),andthatthesampleisnotconnectedtoanenergizedcircuit.

To perform the voltage test:• SettherangeselectiontoMΩ500VorMΩ1000V(Model1015only)• Connectandreadonthevoltagescale(600VACmax)

If a load such as a motor,heater, etc., is attached to theotherend of the line, it will read the loadresistance to ground at the sametime. By removing the jumpers, readingscanbemadebetween the individualconductorsandground.
