Hello all,
I want to use a thermocouple to measure the Temperature of a heater. Referring to the "SCB 68 User Manual for Advanced Functions" (http://www.ni.com/pdf/manuals/372551a.pdf) we installed a resistor at position A and connected the thermocouple single ended as shown on page 4-6.
My Problem ist: Is this installation correct?
I dont really understand the funcion of the resistor and how to measure the temperature now. When i want to measure the temperature with MAX, he expect a differential-measurement.
Thank you for your help.
Best regards
Ivo

Hey Ivo,
thanks for adding the manual. You have to connect a thermocouple differential. This means AI0(+) and AI8(-), instead of connecting it to GND. Here you find the expaination of the differences (german):

Hope this helps
