Fluke 353 Clamp Meter Repair and Calibration
The Fluke 353 is a true-RMS AC/DC clamp meter — a higher-capacity clamp (to ~2000 A) measuring large currents by clamping around a conductor, plus voltage and resistance, for industrial and heavy-electrical work. Its accuracy depends on the current-sensing jaw and the measurement circuitry, which is where service and calibration focus.
June Company repairs and calibrates the Fluke 353 for industrial electricians and maintenance teams.
Common Fluke 353 problems we fix
- Communication / output faults — any analog/data output not working, repaired.
- Current readings inaccurate or drifting — current-sensing jaw or measurement-circuit drift, recalibrated against standards.
- Clamp jaw won’t read or is erratic — jaw mechanism or sensor faults, repaired.
- Voltage/resistance functions off — the lead-input path, recalibrated.
- Display or power faults.
FAQs
My 353 clamp readings are off — fixable? Yes. Current-sensing and measurement drift is repairable and recalibrated, then verified so all functions read accurately, with a NIST-traceable certificate.
Do you calibrate all functions? Yes — current, voltage, and resistance are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or submit a service request.
