Troubles with AI_02.04 specifically
-
Hello all,
I have troubles measuring my PT100 on the AI_02.04 input connection. I applied the same configuration as I did for the other AI_02.xx ones. Those work fine since months. Only the AI_02.04 connection which I wanted to use now shows me the constant value of -246.861.Does anyone else had or has such a problem? What am I doing wrong? 🤔

Hi @matyi,
the value -246 is close to absolute zero. I guess you have set the transformation of the temperature, but it looks like the raw measured value is 0ohms. That would be the problem of the AI not being properly configured. When you change the mode to Resistance measurement, you need to upload the module's configuration "Configure Unipi Module". See more about it here: https://kb.unipi.technology/en:sw:01-mervis:unipi-configure-module-hiddenBest regards,

Oh yeah. I missed that part 🙈:

Thanks for your help! :-)
