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.
Shipping & Returns
Packing your equipment. You are responsible for packaging equipment adequately for transit. We strongly recommend the original manufacturer’s case, or double-boxing with at least two inches of shock-absorbing material on all six sides. We return your equipment in the packaging it arrived in, so please send it in packaging that will survive the return trip as well. If your packaging is damaged or inadequate for the return, we will substitute suitable packaging and may charge the cost of materials.
Insurance. Equipment is not insured by June Company while in transit. We strongly recommend insuring your shipment for its full replacement value.
Risk of loss. Risk of loss remains with you until your equipment is received at our facility, and transfers back to you when your repaired unit is delivered to the carrier (F.O.B. shipping point). June Company is not responsible for equipment lost, delayed, misdelivered, or damaged in transit, in either direction.
Return label. A prepaid and preprinted return shipping label should be included with your shipment. If one is not included, we will provide one.
Transit damage. Damage occurring in transit is the responsibility of the carrier. It is not a warranty defect and is not covered by the 90-day repair warranty. Any claim must be filed by you with the carrier; we will supply photographs and documentation to support it at no charge.
