ni 435x TBX-68T two channels with thermocouples

[gimazz]

Hi everybody,

I'm new to Labview and i'm trying to acquire temperature data; How can I get two Temperature data from two thermocouples in the same VI and display them in the same chart? In another discussion, I've read to write in the "channel string" the number of the channels separated by ":", in my example, "2:3", it's the only way? Do I have to make changes to the acquisition parameters? With one acquisition I'm using this VI (attached);

Thank you all for the patience!:)

Hi Gimazz,

yes it is the correct way. Why cannot you use this method? Does it work fine?

Best regards.

Ok now it works! My problem was also to display them, I solved this with an "index array" that extract column 0 and 1 (0 means channel 2, 1 channel 3) from the 2-D array (scaled data) out of the "NI-435x read.vi", and using two charts for each of the 1-D array in output from !index array";

If I wanted to display the two Temp in only one chart, what can I do? (displaying two different group of points)

Thank you Giuseppe for your reply!
