HVACR: "Megger" Insulation Test For AC Compressor (Motor Windings Insulation Resistance) SUPCO M500

Today we will be performing an insulation test (Meg a Motor/Megging a Motor/Megger a Motor) for a refrigeration compressor using the Supco M500 megohmmeter. We are looking for 100 megohms and greater according to this meter as well as a general rule of thumb to diagnose the motor as good. We are checking the insulation surrounding the motor windings.
The Supco M500 Insulation Tester/Electronic Megohmmeter is an alternative to taut band megohmmeters. It gives you accurate and fast measurements to verify the condition of insulation. As it comes with a soft carrying case, The Supco M500 Insulation Tester/Electronic Megohmmeter can be used in applications such as testing motor winding insulation and diagnosing heat damaged and deteriorating insulation in hermetic refrigeration compressors, appliances, panel boards, relay control circuits, motors and more. Measure insulation values up to 1000 megohms @ 500VAC.
