how to use acquired values for different treatments with NI 9188 cDAQ

[newbieeng]

hi guys, I am trying to use NI DAQ 9188 chasis with 9214 temperature measurement module. I wired 3 modules to the module and split signals. But I am not sure that I can these values into functions vis easily. I am trying to convert them into 1D array, but when I converted to the 1D array I can not see the values and use separetely from each other. For example, I want to multiply just the first value taken from 1st thermocouple. how could I do this. Additionally, the signals in the waveform chart 1 is not smooth. what is the reason of this? thanks in advance.

Hi newbieeng,

It sounds like what you want to use is the Index Array function. You should use the Convert From Dynamic Data function on the signal coming from the DAQ Assistant and then use the Index Array function to access the apropriate data on which you would like to operate. Please refer to the help documentation for more information on the Index Array function. As far as smoothening the signal, try adjusting the properties of the graph, such as Autoscale X and some others in the Properties window.
