PXI Programmable power supply Chr52912 Read current is wrong.

[Samuel_Clipsal]

There is a Programmable power supply in our PXI test system, I try to read its output current (about 50 mA) via "Chr5921 Measure.vi", but the reading are wrong.

I think the Chr52912.dll is too old, but I can't find this DLL in ni website.

Anyone get ideal to fix this problem?

Did this instrument used to work? If you are getting data from the device, then I do not think it is a software issue. Maybe, contact Chroma for calibration procedures?

Hi Peter,

Thank you very much for your reply.

This PXI power supply has been calibrated last year, and the DC output voltage is correct.

This is the first time for us to use the current reading function, I just built this subVi, but the reading is incorrect. This is the only PXI power supply in our company.

Is it possible that someone can verify my attached file works?

Regards

Samuel
