Description
AEMC 6472 Ground Tester Repair
The AEMC 6472 Ground Tester is an insulation resistance tester – it generates a high DC test voltage and measures the very small leakage current that results. Those two demands pull in opposite directions, and both have to be verified: producing the voltage, and resolving nanoamps while doing it.
June Company repairs and calibrates the AEMC 6472 Ground Tester for electrical contractors, maintenance electricians, motor shops, and cable testing crews. Every instrument is repaired at component level and verified against reference standards before it ships back, with the measured results documented.
Common AEMC 6472 Ground Tester problems we fix
- High-range resistance readings inaccurate – drift shows first at the top of the range, where the currents involved are smallest.
- Will not discharge the circuit after test.
- Guard terminal or lead faults.
- Timed test or polarisation index functions failing.
- Readings drifted out of tolerance – corrected and verified against reference standards.
- Display, keypad or front-panel faults.
- Battery or charging faults.
- Test voltage low or not generating – a tester producing a fraction of its nominal voltage still returns a plausible resistance figure that is simply wrong.
FAQs
What if it is not economical to repair? We tell you in the quote. The evaluation is free and there is no obligation to proceed.
Only the high ranges are wrong. Meaningful? Yes, and it is a common pattern. High-range accuracy depends on resolving the smallest currents, so drift appears there first.
