Description
Fluke 5720A Calibrator Repair
The Fluke 5720A is a high-performance multifunction calibrator — a metrology-grade reference that sources precise DC and AC voltage, current, and resistance with artifact-calibration support to calibrate high-accuracy meters and instruments in primary calibration labs. Its faults concentrate in the internal reference, the source/output stages, and the range/function switching.
FlukeMeterRepair.com repairs and calibrates the Fluke 5720A for calibration labs and metrology teams.
Common Fluke 5720A problems we fix
- Artifact-calibration faults — the artifact-cal routine not running correctly, repaired.
- Reference / output drift — the reference or an output stage drifting, which compromises every cal it performs, recalibrated against standards.
- A function out of spec — a specific output (V, I, R) drifting, repaired and recalibrated.
- Range / function switching faults — the output routing/relays, restored.
- A function dead — an output path failed, often after a miswire, repaired.
FAQs
My 5720A drifted or artifact cal won’t run — fixable? Yes. Reference, output-stage, and switching faults are repairable, then every function is recalibrated against our standards so the instruments it calibrates are trustworthy, with a NIST-traceable certificate.
Are all functions verified? Yes — each output function is checked against our standards.
Every repair includes NIST-traceable calibration and a 90-day parts-and-labor warranty. Email us or request service.

They replaced our entire front panel as well as the keypad, really making our Fluke calibrator back to full functionality.

We sent our Fluke 5720A calibrator in for sever errors and June Company repaired each failed board and sent us a repair evaluation form before the repair and a repair report after the repair. Happy with the results.
