Description
Fluke 434 Power Quality Analyzer Calibration and Repair
The Fluke 434 is a three-phase power quality analyzer that measures voltage, current, power, harmonics, and PQ events across all phases (with current probes) to IEC 61000-4-30 Class A, with logging. Its accuracy depends on the voltage and current measurement inputs and the acquisition system, so that’s where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 434 for power-quality and electrical-maintenance teams.
Common Fluke 434 problems we fix
- Input-channel faults — a voltage or current input not reading correctly, repaired.
- Readings out of spec — measurement-circuit drift, recalibrated against standards.
- Acquisition / measurement faults — the acquisition system skewing readings, repaired.
- Won’t power on or hold a charge — the aging battery and power section, serviced.
- Display or input faults.
FAQs
My 434 input or reading is off — fixable? Yes. Input and acquisition faults are repairable, then the inputs are recalibrated so power and PQ measurements are accurate, with a NIST-traceable certificate.
Are the inputs verified? Yes — voltage and current inputs are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.
