Description
Fluke 5320A Electrical Tester Calibrator Repair
The Fluke 5320A is a multifunction electrical-tester calibrator — a benchtop standard that sources the quantities needed to calibrate electrical safety testers and installation testers (high resistance, insulation, loop/ground, RCD, continuity). Its precision lives in the specialized source/measure circuits and the internal reference, which is where service and calibration focus.
FlukeServiceCenter.com repairs and calibrates the Fluke 5320A for calibration laboratories, electrical-safety test houses, and instrument-service companies.
Common Fluke 5320A problems we fix
- Output-accuracy / voltage-sourcing faults — a sourced function out of spec, repaired and recalibrated against standards.
- High-resistance / insulation-source faults — the high-resistance or insulation-test simulation out of spec, repaired.
- A function dead — a source/measure path failed, repaired.
- Communication-interface faults — the remote interface not connecting, repaired.
- Power-supply or display faults.
FAQs
My 5320A output is out of spec — fixable? Yes. Source and reference faults are repairable, then every function is recalibrated against our standards so it calibrates your testers accurately, with a NIST-traceable certificate.
Are all functions 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.
