Fluke 435-II Power Quality Analyzer Repair
The Fluke 435-II is a three-phase power quality and energy analyzer — it measures voltage, current, power, harmonics, PQ events, and energy-loss/cost across all phases (with flexible current probes) to IEC 61000-4-30 Class A. 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-II for power-quality engineers, plant managers, and utility teams.
Common Fluke 435-II problems we fix
- Input-protection restoration — protection damaged after an over-range input, repaired.
- Current-input or probe channel faults — a phase not reading from its flexible probe, repaired so all phases measure.
- 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-II — fixable? Yes. Input-channel and protection 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.

We rely on our Fluke 435 analyzer for several jobs. One of our Fluke 435 power quality analyzers had died. June Company did an excellent job repairing and calibrating the meter. Great service.
