I have a SCXI-1102,and two SCXI-1112 in a SCXI-1000 chassis with a SCXI-1303 terminal block. I connected one thermocouple at Channel 0 in SCXI-1300, and also connected other TCS to SXCI-1112. And I tried to measure ambient temperature by T-type thermocouples. In VI, I set CJC type to be constant value, and it automatically set default temperature at 25 degree cellsius. Then I test it, but temperatures by thermocouples are differert from the value of thermometer. So I changed CJC constant values accordingly, and I testest again, It still did not show the right value.
BTW: When the data acquire system run for a long time, such as half an hour, does it affect the data acquired?
