Description
Fluke 435-II Power Quality Analyzer Repair
The Fluke 435-II is an advanced three-phase power quality and energy analyzer (Series II) that measures voltage, current, power, harmonics, PQ events, and energy across all phases to IEC 61000-4-30 Class A, with high-resolution 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-II for power-quality engineers, industrial plant managers, and utility power-quality teams.
Common Fluke 435-II problems we fix
- IEC 61000-4-30 / Class-A measurement faults — PQ parameters out of compliance spec, repaired and recalibrated against standards.
- Current-input or probe channel faults — a phase not reading from its probe, repaired.
- Acquisition / measurement faults — the acquisition engine skewing readings, 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 435-II 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.
