Fluke 435 Power Quality Analyzer Calibration and Repair
The Fluke 435 is a three-phase power quality and energy analyzer — it measures voltage, current, power, harmonics, PQ events, and energy across all phases (with current probes) to IEC 61000-4-30 Class A, with data logging. Its accuracy depends on the voltage and current measurement inputs, so that’s where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 435 for power-quality engineers, plant managers, and utility teams.
Common Fluke 435 problems we fix
- Current-input or probe channel faults — a phase not reading from its probe, repaired so all phases measure.
- Data-logging failures — won’t log or store recordings, the recording/memory restored.
- Readings out of spec — measurement-circuit drift, recalibrated against standards.
- Won’t power on or hold a charge — battery and power faults.
- Display or input faults.
FAQs
One phase isn’t reading on my 435 — fixable? Yes. Input and logging 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.
