NI 4351 giving wrong sensor output

[aguy004@aucklanduni.ac.nz]

Hey guys, thanks in advance for any help recieved.

I have 6 sensors (3 RTD's and 3 thermistors) connected to a NI 4351 and the sensors were giving the right outputs a few months ago, but now all the sensors are giving out very low values. Any help will be greatly appreciated.

Regards,

Alim

Hi Alim,

Have you checked what the sensors are actually reporting? ie remove them from the 4351 and check their resistance manually.

Hey, thanks for the advice. It turns out one of the thermistors was missing its probe connection and so stuffed everything up. Since has been removed and is working all fine. Thanks again 🙂
