Description
Fluke 5520A Multi-Product Calibrator Repair
The Fluke 5520A is a multi-product calibrator that sources precise DC/AC voltage and current, resistance, capacitance, and temperature, with an optional oscilloscope-calibration capability, to calibrate a wide workload of meters and scopes. 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 5520A for calibration laboratories, instrument-service companies, and military metrology labs.
Common Fluke 5520A problems we fix
- Output accuracy out of spec — a sourced function drifting, repaired and recalibrated against reference standards.
- Oscilloscope-calibration option faults — the scope-cal (fast-edge/leveled-sine) outputs not generating correctly, repaired.
- A function dead — a source path failed, often after an external fault, repaired.
- Won’t communicate — the remote interface, repaired.
- Power-supply or display faults.
FAQs
My 5520A 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.
