Model 6517B Electrometer/High Resistance Meter Insulation Resistance Testing

Simple concepts will be shown to make stable, accurate high resistance readings of cable insulation resistance in the 10¹⁴ Ω range.  The 6517B Electrometer/High Resistance Meter is capable of making resistance measurements up to 10¹⁸ Ω.  The 6517B's built-in 1000 V source will output 100 V and measure picoamps to determine the insulation resistance of a long piece of wire.
