Fluke 377 FC Clamp Meter Repair

Description

Fluke 377 FC Clamp Meter Repair

The Fluke 377 FC is a true-RMS clamp meter with Fluke Connect, non-contact voltage, and an iFlex flexible current probe, measuring AC/DC current plus voltage and resistance. Its accuracy depends on the clamp jaw/Hall sensor (and any flexible iFlex probe) and the measurement circuitry, which is where repair and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 377 FC for electricians, HVAC technicians, and industrial maintenance crews.

Common Fluke 377 FC problems we fix

• Inrush-capture circuit faults — the inrush-current measurement not capturing correctly, repaired and recalibrated.
• Jaw realignment / Hall-sensor recalibration — a misaligned jaw or drifting sensor giving erratic readings, realigned and recalibrated against standards.
• Rotary-switch wear — intermittent function selection, repaired.
• Battery or terminal faults.

FAQs

My 377 FC 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.
