Yesterday I made a panel for 4 digital thermometers connected with 4 Temperature Sensor Probes RTD PT100. Everything worked out fine, only on meter is reading 400 C, what is the max. temp. the rest is fine. I switched the probe to another meter and the problem seems to be the probe I the manual they also speak of min. and max. display, display off set, but I have no idea how to get these values.

Looks good mate. I know on my meter if i plug the probe in the wrong way round i get funny values.

Make sure the resistance contact is on the correct terminal.

Thanks punkin, I'm going a bit slower then you guy's, learning a lot and having great fun. My next step will be a PID to control my cooling temp.
@ OD . I tried every possible way to connect but with no result. Will buy a new one.
Today Tig welded 3 nippels of 1/8" on my column to fit the probes
are all of the wires on that sensor the same resistance?
