Description
Fluke 6003A Three-Phase Electrical Calibrator Repair
The Fluke 6003A is a three-phase electrical power and energy calibrator — a metrology-grade source that generates precise three-phase voltage, current, and phase to calibrate energy meters, power analyzers, and reference standards. As a precision multi-phase source, its faults concentrate in the output (amplifier) stages, the phase/reference electronics, and the control system.
FlukeMeterRepair.com repairs and calibrates the Fluke 6003A for energy-meter and power calibration labs.
Common Fluke 6003A problems we fix
- Reference-source degradation — the voltage/current/phase reference drifting, recalibrated against standards.
- Output-stage faults — a voltage or current phase weak or dead, repaired so every output meets rated level.
- Phase-accuracy faults — the phase reference drifting, corrected.
- Control / communication faults — the control interface, restored.
- Display or power faults.
FAQs
My 6003A output or phase is off — fixable? Yes. Reference and output-stage faults are repairable, then the calibrator is recalibrated so its three-phase outputs are accurate and the meters you calibrate are trustworthy, with a NIST-traceable certificate.
Is the phase verified? Yes — phase and amplitude are checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.

Our electrical calibrator was damaged in transit. We sent it to June Company, they quoted it the very next day, and it was back to us repaired within a week. Great job.
