Fluke 345 Power Quality Clamp Meter Repair and Calibration
The Fluke 345 is a power quality clamp meter — it clamps around a conductor to measure current, voltage, power, harmonics, and even DC ripple, with logging, aimed at troubleshooting switching loads and power-quality issues in the field. Its accuracy depends on the current-sensing jaw and the measurement/analysis circuitry, which is where service and calibration focus.
June Company repairs and calibrates the Fluke 345 for electricians and power-quality technicians.
Common Fluke 345 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.
- Harmonics / power measurement off — the analysis circuitry, restored.
- Won’t log or display — logging or display faults, repaired.
- Won’t power on or charge — battery/power faults.
FAQs
My 345 clamp or power readings are off — fixable? Yes. Current-sensing and measurement drift is repairable and recalibrated, then verified so current, power, and harmonics read accurately, with a NIST-traceable certificate.
Do you calibrate all functions? Yes — current, voltage, and power 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.
