Description
Associated Research 8204 Safety Tester Repair
The Associated Research 8204 (HypotULTRA) is an electrical safety compliance analyzer — it performs AC/DC hipot, insulation resistance, and ground-bond testing in one instrument for production safety testing to UL/IEC standards. It combines an HV source, leakage metering, and a high-current ground-bond source, so faults can appear across all three functions.
June Company repairs and calibrates the Associated Research 8204 for production safety-test and QC teams.
Common Associated Research 8204 problems we fix
- Leakage-current measurement drift — the metering your hipot pass/fail depends on, recalibrated against standards.
- Ground-fault / ground-bond faults — the high-current GB source or ground-fault detection not working, repaired.
- HV won’t reach voltage or trips — HV output-stage faults, rebuilt.
- Insulation-resistance function faulty — the IR measurement, restored.
- Interlock, display, or control faults.
FAQs
My 8204 leakage or ground-bond is off — fixable? Yes. Metering and GB-source faults are repairable, then recalibrated so hipot, IR, and ground bond pass/fail correctly, with a NIST-traceable certificate.
Are all three functions verified? Yes — hipot, IR, and ground bond are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
