i'm currently using a PT104 for temperature measurements using a PT100. However, since i'm using the Ethernet protocol, i need to convert the resistance value into a temperature value. The user's guide provides the formula for the resistance as a function of the temperature, and i need the inverse function. I was searching in the software usbpt104con.c in the folder /opt/picoscope/share/doc/libusbpt104 for the conversion formula but i didn't find it anywhere. Can you please write the exact formula to convert the PT100 resistance value into a temperature value?
Thank you very much, best regards
