M500 Megohmmeter Tester
This reliable, battery operated instrument,complete with LED indicators, will accurately measure insulation values up to 1000 megohms at 500 volts and also indicate the condition of insulation on the zone scale.
- Remove ALL wires that are connected to the terminals that are to be tested
- Attach one test lead from the megohmmeter to ANY WINDING TERMINAL andthe other test lead to the METAL CASE of the motor Make sure the point ofcontact is clean to the BARE METAL (no paint)
- Depress “POWER" button, wait approximately 10 seconds then proceed toread the insulation value shown on the corresponding illuminated LED lamp
Engineered for professional technicians, the M500 Megohmmeter combines precision, durability, and ease of use. Its clear LED scale with "Bad/Caution/Good" zones lets you quickly assess insulation health at a glance, while the impact-resistant ABS casing stands up to daily wear and tear in any work environment.
