Description
Fluke 5720A Multifunction Calibrator Repair
The Fluke 5720A is a reference multifunction calibrator — a primary-lab-grade source of precise DC/AC voltage and current and resistance with very low uncertainty, used to calibrate high-accuracy DMMs and instruments. Its precision lives in the multiple precision source circuits and the internal reference, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 5720A for calibration laboratories, instrument-service companies, and military metrology labs.
Common Fluke 5720A problems we fix
- Output-compliance faults — an output not driving its rated load/compliance, repaired and recalibrated against standards.
- Reference-source restoration — the internal reference out of spec, repaired.
- Output-amplifier drift — a sourced function out of spec, recalibrated.
- Won’t communicate — the remote interface, repaired.
- Power-supply or display faults.
FAQs
My 5720A output is out of spec — fixable? Yes. Source and amplifier faults are repairable, then every output is recalibrated against our reference standards so it calibrates your workload accurately, with a NIST-traceable certificate.
Are all outputs verified? Yes — each 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.
