Fluke 353 Clamp Meter Calibration and Repair
The Fluke 353 is a high-current true-RMS clamp meter measuring large AC currents (via a heavy-duty clamp) plus voltage and resistance for industrial and utility electrical 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 353 for electricians and maintenance technicians.
Common Fluke 353 problems we fix
- Large-jaw / sensor faults — the large clamp jaw not seating or reading consistently, repaired.
- High-current measurement out of spec — the measurement drifting, recalibrated against standards.
- A function dead — a measurement path failed, repaired.
- Display or battery faults — repaired.
- Terminal or function-switch faults.
FAQs
My 353 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.
