PXIe-4139 calibration fails. Overload protection at any voltage

[Basjong53]

I have a PXIe-4139 in a PXIe-1083 chassis connected to a thunderbolt port. Since today the board gives a lot of errors. It goes in overvoltage protection even though it is in potentiostatic mode pushing only ~0.6 V. Could be a range issue, but even with autorange of and manually set to 6V, it still gives errors. Often times it give internal hardware errors. InstrumentStudio doesn't smoothly show the voltage and current being plotted.

Then the Self-Calibrate function in NI MAX doesn't work either. It gives error -1074118653.

I've uninstalled all NI software and reinstalled DC-Power 21.5. Issue remains.

I've tried to follow as many steps as I can from here: https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019Ot2SAE&l=en-GB, but the system is at a customer, so I cannot do any hardware changes.

Is there anything I can do?

'Internal Hardware Error' - this signifies something big is at play and potentially damaged hardware that requires repair/replace.

Yes, that error is quite worrying. Is there anything I can do to check if it's really a hardware problem? Because that would be a big inconvience as we don't have a replacement due to the long delivery times of NI.

If you have another PXI system, I would try the 4139 on that.

In the past, every time I faced a Hardware error, the SMU had to be replaced, sometimes it will just work fine as long as you don't calibrate or reset but eventually, the destiny is to repair or replace it.

If your application requires the SMU to abide by the specifications, you need to calibrate and you have got a potentially damaged SMU.
