Description
Fluke 1662 Installation Tester Repair
The Fluke 1662 is a multifunction electrical installation tester — it performs the safety tests required to certify electrical installations (insulation resistance, continuity, loop/line impedance, and RCD/GFCI testing) to wiring regulations. As a multi-function tester, its faults span the test sources (insulation HV, loop, RCD) and the measurement circuitry.
June Company repairs and calibrates the Fluke 1662 for electricians and installation-test teams.
Common Fluke 1662 problems we fix
- RCD test-circuit faults — the RCD/GFCI test not tripping or timing correctly, repaired and recalibrated.
- Loop / line-impedance measurement off — the loop-test measurement drifting, recalibrated against standards.
- Insulation-test (HV) faults — won’t reach test voltage or reads wrong, repaired.
- Continuity-measurement faults — restored.
- Display, battery, or lead faults.
FAQs
My 1662 RCD or loop test is off — fixable? Yes. The RCD and loop circuits are repairable and recalibrated, then verified so installation test results are accurate, with a NIST-traceable certificate.
Are all functions verified? Yes — insulation, continuity, loop, and RCD 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.
