Fluke 345 Calibration

Description

Fluke 345 Power Quality Clamp Meter Calibration and Repair

The Fluke 345 is a power quality clamp meter — it clamps around a conductor to measure current, voltage, power, harmonics, and basic power quality (with logging and a graphical display), ideal for troubleshooting variable-frequency drives and switching loads. Its accuracy depends on the clamp jaw/current sensor and the measurement/acquisition circuitry, which is where repair and calibration focus.

FlukeMeterRepair.com repairs and calibrates the Fluke 345 for electricians, PQ, and drive-maintenance teams.

Common Fluke 345 problems we fix

• Clamp-jaw / current-sensor faults — a damaged or misaligned jaw giving erratic readings, repaired and recalibrated.
• Harmonics / PQ measurement faults — the harmonics or power measurements reading wrong, recalibrated against standards.
• Logging / display faults — the onboard logging or graphical display, repaired.
• A function dead — a measurement path failed, repaired.
• Won’t power on or hold a charge — battery/power faults.

FAQs

My 345 current or harmonics reading is off — fixable? Yes. Jaw and measurement faults are repairable, then the meter is recalibrated so current, power, and PQ 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.
