Title: 5720A Ohms PCB Failure
Post by: CALSQUID81 on 09-27-2012 -- 06:42:34
Is anyone having problems with Fluke 5720A calibrators continually blowing A10 boards? We've had several in the last few months.

We sent a unit to Fluke in March. The user was telling us that the unit would not switch to the 190 kOhm w/ External sense value reliably under GPIB.
Fluke replaced the A10 Ohms Main Assembly.
We sent the unit back to the user, but the unit is being returned to us again for the same problem.

It's a motorcycle with an airplane sidecar.

Back to the subject at hand. I was just wondering can you get an extended warranty on that? If it is a known problem maybe Fluke has a program to cover that?

According to Fluke, there is no known problem, so as of right now we're trying to identify potential internal process issues.
