Fluke 434 Power Quality Analyzer Repair

The Fluke 434 is a three-phase power quality analyzer that measures voltage, current, power, harmonics, and PQ events (sags, swells, transients) across all phases with current probes, with logging. Its accuracy depends on the voltage and current measurement inputs and the acquisition engine, so that’s where service and calibration focus.

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

Common Fluke 434 problems we fix

Voltage sag / swell capture faults — the event-capture not triggering or logging correctly, repaired.
Harmonics-measurement faults — harmonics reading out of spec, recalibrated against standards.
Current-input or probe channel faults — a phase not reading from its probe, repaired.
Won’t power on or hold a charge — the aging battery and power section, serviced.
Display or input faults.

FAQs

One phase or function on my 434 is off — fixable? Yes. Input and acquisition faults are repairable, then all inputs are recalibrated 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.
