Joey,
I took a look at this instrument driver, and it appears that there is not a built-in function that allows you to read multiple channels at the same time. You will need to have multiple subVIs read channels individually, then build those values into an array of all the temperatures. This is the only way I could find to get an array of your temperatures after my cursory glance of the driver.
Good luck with your application, and have a pleasant day.
Sincerely,
