Status: 5730A Current Production — 5700A / 5720A Discontinued. We repair and calibrate all of them.
Common Fluke 5700 Series Problems We Fix
- Output out of tolerance or drifting beyond rated ppm accuracy
- DC voltage reference drift requiring recalibration to standards
- Resistance or AC voltage output inaccurate
- Won’t power on or intermittent power faults
- Dead display or failed front-panel encoder (5700A / 5720A)
- Relay or range-switching faults from cumulative cycles
- Current amplifier drift or instability under heavy load
- Won’t communicate over GPIB / USB (MET/CAL automation fails)

Frequently Asked Questions
How much does Fluke 5700 Series 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 5700 Series repairs are finished within 5–10 business days of arrival. Because these are primary reference standards, we can discuss expedited turnaround if your lab is down.
My calibrator has drifted out of spec — can you bring it back to its ppm accuracy?
Yes. DC voltage reference drift and resistance-network degradation are the most common 5700 Series faults. We repair the cause and verify performance against our reference standards to restore rated accuracy.
Do you still repair the discontinued 5700A and 5720A?
Yes. These legacy multifunction calibrators are fully supported — including front-panel encoder and display failures common on older units — even though they’re no longer in production.
Do you repair the 5725A and 52120A amplifiers too?
Yes. We service the 5725A range-extending amplifier and the 52120A transconductance amplifier (current output to 6000 A), restoring and verifying their extended ranges.
Is the repair NIST-traceable, and do I get a certificate?
Yes. Every repair includes NIST-traceable calibration of the primary output functions, documented on a certificate against Fluke’s published specifications — essential for a primary standard in your lab.
What if my exact model isn’t listed?
We service every 5700 Series configuration. If your model isn’t in the table, pick the closest match or email us — the process is the same.
Who uses the Fluke 5700 Series?
National metrology institutes, primary standards laboratories, aerospace and defense calibration, and high-accuracy calibration providers rely on the 5700 Series for 8.5-digit DMM and reference-standard calibration.
