Fluke 355 AC/DC Clamp Meter Repair

Description

Fluke 355 Clamp Meter Repair

The Fluke 355 is a high-current true-RMS AC/DC clamp meter measuring large AC/DC currents (via a heavy-duty clamp) plus voltage and resistance, with extended range, for industrial and utility electrical work. Its accuracy depends on the clamp jaw/Hall sensor and the measurement circuitry, which is where repair and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 355 for electricians, HVAC technicians, and industrial maintenance crews.

Common Fluke 355 problems we fix

• True-RMS / current measurement out of spec — the measurement drifting, recalibrated against standards.
• Jaw realignment / Hall-sensor recalibration — a misaligned jaw or drifting sensor giving erratic readings, realigned and recalibrated.
• Display repair — missing segments or a dim display, repaired.
• Rotary-switch faults — intermittent function selection, repaired.
• Battery or terminal faults.

FAQs

My 355 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.
