Fluke 377 Clamp Meter Calibration and Repair
The Fluke 377 is a true-RMS clamp meter with non-contact voltage and an iFlex flexible current probe, measuring AC/DC current plus voltage and resistance for electrical troubleshooting. Its accuracy depends on the clamp jaw/current sensor (and any flexible probe) and the measurement circuitry, which is where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 377 for electricians and maintenance technicians.
Common Fluke 377 problems we fix
- iFlex flexible-probe faults — the flexible current probe not reading correctly, repaired and recalibrated.
- Clamp-jaw / current-sensor faults — a damaged or misaligned jaw giving erratic readings, repaired.
- Current measurement out of spec — the measurement drifting, recalibrated against standards.
- Display or battery faults — repaired.
- Terminal or function-switch faults.
FAQs
My 377 clamp reading is off — fixable? Yes. Jaw and measurement faults are repairable, then the clamp meter is recalibrated so current and other readings are accurate, with a NIST-traceable certificate.
Is the clamp verified? Yes — the jaw (and iFlex probe, if included) and all functions are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
