Description
Fluke 1773 Power Quality Analyzer Repair
The Fluke 1773 is a three-phase power quality analyzer (1770 series) — it measures voltage, current, power, harmonics, and PQ events 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 system, so that’s where service and calibration focus.
FlukeMeterRepair.com repairs and calibrates the Fluke 1773 for power-quality engineers, plant managers, and utility teams.
Common Fluke 1773 problems we fix
- ADC / resolution loss — the acquisition system losing resolution and skewing measurements, repaired and recalibrated against standards.
- Data-logging failures — won’t log or store recordings, the recording/memory restored.
- Current-input or probe channel faults — a phase not reading from its probe, repaired.
- Readings out of spec — measurement-circuit drift, recalibrated.
- Battery, power, or display faults.
FAQs
My 1773 readings or logging are off — fixable? Yes. Acquisition, logging, 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.
