Fluke 337 Clamp Meter Calibration and Repair
The Fluke 337 is a true-RMS clamp meter measuring AC/DC current plus AC/DC voltage, resistance, and temperature for advanced electrical and motor work. Its accuracy depends on the clamp jaw/current sensor and the measurement circuitry, which is where repair and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 337 for electricians and maintenance technicians.
Common Fluke 337 problems we fix
- True-RMS / current measurement out of spec — the measurement drifting, recalibrated against standards.
- Clamp-jaw / current-sensor faults — a damaged or misaligned jaw giving erratic readings, repaired.
- A function dead — a measurement path failed, often after an overload, repaired.
- Display or battery faults — repaired.
- Terminal or function-switch faults.
FAQs
My 337 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 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.
