Fluke 435 Power Quality Analyzer Repair
The Fluke 435 is a three-phase power quality and energy analyzer that measures voltage, current, power, harmonics, PQ events, and energy across all phases to IEC 61000-4-30 Class A, 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 435 for power-quality engineers, industrial plant managers, and utility power-quality 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.
- Readings out of spec — measurement-circuit drift, recalibrated against standards.
- Data-logging faults — won’t log or store recordings, the recording/memory restored.
- 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 435 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.

Our Fluke 435 died, replaced battery and still would not power on. Sent to June Company, and they gave us a quote the same day. Great price and quick turnaround time.
