Fluke 374 Clamp Meter Repair and Calibration
The Fluke 374 is a true-RMS AC/DC clamp meter — it measures current up to 600 A by clamping around a conductor, plus voltage and resistance through its leads, for electrical troubleshooting and maintenance. Its accuracy depends on the current-sensing jaw and the measurement circuitry, so that’s where service and calibration focus.
June Company repairs and calibrates the Fluke 374 for electricians and maintenance technicians.
Common Fluke 374 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 measurement path, recalibrated.
- Display segments missing or dim — display faults, repaired.
- Won’t power on — battery-contact or power-circuit faults.
FAQs
My clamp readings are off — fixable? Yes. Current-sensing and measurement-circuit 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 all 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.
