Hello,
For few days I have a problem to run temperature measrement usint PT100 connected to BNC-2120. Maybe it's wrong connection, maybe problem with configuration - i don't have idea.
As above, PT100 (3 wire) is connected do BNC-2120 via RES+ and RES- terminals. 2 wires are connected to the card, one of linked wire is not connected. In DAQ assistant analog resistance input were created, but during the test it returns resistance around 50-54Ohms instead approx.107Ohm in room temperature. I tried all possible connection, only effect is that return resistance were changed to 1kOhm.
I tried to configure DAQ as RTD but on the liste there is no PT100 device, after choosing Custom i have to write in three coefficients - A, B, and C. In PT100 datasheet there is no information about it - may i calculate it from charts? or how can i get them?
Thanks so much for help.
