I am trying to record resistance using the 4-Wire resistance setting along with temperature and voltage using the appropriate DAQ cards for each. When attempting to record resistance at -20 degrees C, the temperature and voltage will record, but not the resistance from the DMM even though SignalExpress is showing the signal from the DMM and is reading the data as shown on the laptop. With the same setup, I can record all 3 items at -10 degrees C, 0 degrees C, etc. I have verified my connections, I have swapped out cables and connectors and the data only fails to record at -20 degrees C. Any thoughts or solutions would be appreciated.
