Fluke 434 Three Phase Power Quality Analyzer-Remanufactured

Description

Fluke 434 Three-Phase Power Quality Analyzer (Remanufactured) Repair

This is the repair, calibration, and remanufacture listing for the Fluke 434 — a three-phase power quality analyzer measuring voltage, current, power, harmonics, and PQ events across all phases (with current probes) to IEC 61000-4-30 Class A, with logging. Remanufacture restores a used unit to full spec; whatever the starting condition, accuracy depends on the voltage and current measurement inputs.

FlukeMeterRepair.com repairs, remanufactures, and calibrates the Fluke 434 for power-quality engineers, plant managers, and utility teams.

Common Fluke 434 problems we fix

• Input-protection restoration — protection damaged after an over-range input, repaired.
• ADC / acquisition board repair — acquisition faults skewing measurements, restored.
• Probe-interface recalibration — current-probe inputs drifting, recalibrated against standards.
• Battery, power, or display faults — serviced (a remanufactured unit typically gets a fresh battery).
• Readings out of spec — measurement-circuit drift, recalibrated.

FAQs

Can you bring a used 434 back to spec? Yes. We repair input, ADC, and battery faults, then recalibrate all inputs so power, harmonics, and PQ measurements are accurate, with a NIST-traceable certificate.

Are the current inputs verified? Yes — checked against our standards.

Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
