Description
Associated Research 7720 Compliance Tester Repair
The Associated Research 7720 is an electrical safety compliance tester — it performs dielectric-withstand (hipot) and related safety testing for production compliance to UL/IEC standards, applying high voltage and measuring leakage current, with a safety interlock. It combines an HV source with leakage metering, so faults span both sides.
June Company repairs and calibrates the Associated Research 7720 for production safety-test and QC teams.
Common Associated Research 7720 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.
- Safety-interlock malfunctions — won’t energize or trips immediately, the interlock repaired without compromising safety.
- False fails or misses — detection-threshold or front-end faults, corrected.
- Display or control faults.
FAQs
My 7720 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 — output is 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.
