Description
AEMC 6505 Megohmmeter Repair
The AEMC 6505 is a 10 kV insulation resistance tester (megohmmeter) — it applies test voltages up to 10 kV and measures insulation resistance into the tera-ohm range, with timed diagnostic tests (PI, DAR) for assessing motor, cable, and transformer insulation. The hardworking part is the high-voltage generator that has to hold a stable selected voltage, so that’s where most faults originate.
June Company repairs and calibrates the AEMC 6505 for electrical maintenance crews, motor shops, and testing labs.
Common AEMC 6505 problems we fix
- HV generator rebuild — won’t reach the selected 5/10 kV or output is low, the most common 6505 fault, rebuilt so it hits full rated voltage.
- Measurement-amplifier recalibration — resistance readings drifting or unstable, recalibrated against standards.
- Range-switch repair — intermittent voltage/range selection from contact wear.
- Multi-voltage verification — confirming each test-voltage step is accurate.
- Display, battery, or interface faults.
FAQs
My 6505 won’t reach 10 kV — fixable? Yes. HV generator faults are the usual cause and they’re repairable, then verified so the tester delivers full rated voltage and your readings are valid, with a NIST-traceable certificate.
Do the PI/DAR functions get verified? Yes — the diagnostic timed tests are checked along with recalibration.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
