Fluke 336 Clamp Meter Repair and Calibration
The Fluke 336 is a true-RMS AC/DC clamp meter — it measures current by clamping around a conductor, plus voltage, resistance, and continuity, for routine and industrial 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 336 for electricians and maintenance technicians.
Common Fluke 336 problems we fix
- 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 faults — missing or dim segments, repaired.
- Won’t power on — battery-contact or power faults.
FAQs
My 336 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.
