Fluke 1770 Power Quality Analyzer Repair
The Fluke 1770 series is a three-phase power quality analyzer — it measures voltage, current, power, harmonics, flicker, and PQ events (including transients) across all phases (with current probes) to IEC 61000-4-30, with logging. Its accuracy depends on the voltage and current measurement inputs and the acquisition engine, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 1770 for power-quality engineers, industrial plant managers, and utility power-quality teams.
Common Fluke 1770 problems we fix
- Transient-capture / flicker faults — transient capture or flicker measurement returning wrong results, 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 — battery and power faults.
- Display or input faults.
FAQs
One phase or function on my 1770 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.
