Description
Associated Research 3865 Compliance Tester Repair
The Associated Research 3865 is an electrical safety compliance tester — it performs AC/DC hipot (dielectric withstand) and related safety tests for production compliance to UL/IEC standards, applying high voltage and measuring leakage to pass/fail products. It combines an HV source with precision leakage metering, so faults span both.
June Company repairs and calibrates the Associated Research 3865 for production safety-test and QC teams.
Common Associated Research 3865 problems we fix
- Leakage-current measurement off — the metering your hipot pass/fail depends on, recalibrated against standards.
- Won’t reach test voltage or trips — HV output-stage faults, rebuilt for stable rated output.
- False fails or misses — detection-threshold or front-end faults, corrected.
- Interlock or control faults — won’t energize or trips immediately.
- Display or interface faults.
FAQs
My 3865 leakage reading is off — fixable? Yes, and it’s the critical hipot repair. We recalibrate the leakage metering against our standards so the number you certify against is accurate, with a NIST-traceable certificate.
Is the HV output verified? Yes — AC and DC output are checked along with the metering.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
