Fluke Electrical Tester Calibrator Repair (5320A, 5322A)

Status: 5322A Current Production — 5320A Discontinued. We repair and calibrate both.

Common Fluke 5320A / 5322A Problems We Fix

  • Insulation resistance simulation out of tolerance or not working
  • Loop impedance values reading inaccurate / resistor network drift
  • RCD trip-time simulation inaccurate or unstable
  • Earth resistance simulation out of spec
  • No output or unstable output on one or more functions
  • Won’t power on or front-panel interface fault
  • Won’t communicate over GPIB / USB (MET/CAL automation fails)

Frequently Asked Questions

How much does Fluke 5320A / 5322A repair cost?

Repairs start with a flat evaluation fee that’s credited toward your repair cost. After we diagnose the unit, you get a firm quote before any work begins — no surprises.

How long does the repair take?

Most 5320A and 5322A repairs are finished within 5–10 business days of arrival. Because these are reference calibrators, we can discuss expedited turnaround if your lab is down.

My calibrator’s simulation values are out of tolerance — can you bring them back into spec?

Yes. Insulation resistance, loop impedance, and RCD timing circuits drifting out of tolerance are the most common repairs on these units. We correct the cause and verify each function against our reference standards.

Do you repair the RCD trip-time and loop-impedance functions specifically?

Yes. We service the full workload these calibrators cover — insulation resistance, loop/RCD, and earth ground simulation — restoring and verifying each one individually.

Do you still repair the discontinued 5320A?

Yes. The 5320A is no longer in production but fully supported for repair and recalibration alongside the current 5322A.

Can you fix GPIB/USB faults that break MET/CAL automation?

Yes. Communication faults that stop automated calibration sequences are a common repair, restored so your MET/CAL procedures run again.

Is the repair NIST-traceable, and do I get a certificate?

Yes. Every repair includes NIST-traceable calibration of the simulation and output functions, documented on a certificate against Fluke’s published specifications.

Who uses the Fluke 5320A / 5322A?

Electrical safety test laboratories, installation tester calibration programs, regulatory compliance facilities, and electrical contractor calibration labs rely on these to calibrate safety, loop, RCD, and insulation testers.
