DAQmx Create Virtual Channel AI Temp TC Deg F Bug

[Brian_ECE_2015]

Found a bug in DAQmx Create Virtual Channel AI Temp TC Deg F when using a cDaq-9174 with a NI 9213 Analog Inpout module.  When I change from Deg C to Deg F I do not get the correct temperature.  In Deg C I read ambient temp of 21.84 Deg C Vs. when I select Deg F I read 18.33 Deg F.   When I use the DaqMX Assistant the asssitant returns the correct values.  Is this a know bug on the 9213 driver?  What is the fix?

Not a bug at all but a small problem with your understanding of the CJC parameters.  Assuming the constant "25" is probably fairly close for deg C but unless you work in a refrigerator it might not be the best choice for Deg F  

Hint: Use "Built in" as the CJC source
