I am trying to use the same SCXI 1100 module to measure temperatures from 2 different sources. One source uses E-Type of thermocouples while the other uses K-type of thermocouples. I will be physically connecting the 15 E type of TC's in the 0 to 14 channels of the SCXI-1100 module and the 5 K-type of TC's in channels 15 to 19. I have two questions. First, how do I take care of the different types of thermocouples. What I tried to do is to scan the two set of channels (E-type and K-type) separately as you can see in the attached vi. However when I specify the list of channles to scan as ob0!sc1!md1!0:14 (for E-type) and ob0!sc1!md1!15:19 (for K-type), I get some "Error - 10001 at AI-Config group" error. When I change
the channel list for K-Type of TC's to
ob0!sc1!md1!20:24, I do not get the error. Can you tell me why ?
My next question, is there a better way to do what I am doing, I is it really necessary scan the different set of channels differently ? Also I am expecting to see a array of 15 (for E-Type) and 5 (K-Type) number when I as an output, but I see only one element for both of them, any reasons why thats happening ? something wrong with the vi ?
Thanks a lot !!
