Description
Fluke 435 Power Quality Analyzer 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
- Data-logging failures — won’t log or store recordings, the recording/memory system restored.
- GPS-sync faults — the time-sync/GPS function not working, repaired.
- 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.
- Battery, power, or display faults.
FAQs
My 435 won’t log or sync — fixable? Yes. Logging, sync, and input 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.

One of our Fluke 435 power quality analyzers stopped powering up. Changed the batteries and tried to charge and use them with line power, but still would not power up. Sent in for repair to June Company. I received a detailed quotation from the technicians, and I approved the repair and calibration. Received the analyzer back in good working order and a calibration certificate.

Our Fluke 435 power analyzer display was cracked by a technician in the field. Fluke no longer provides repair service for this meter, and we found June Company. They did a great job with the repair and ISO-17025 calibration service. Very satisfied with the entire process.
