Hi guys, I have a national instruments NI USB-6009 device connected to the computer and I trying to import 3 single-ended input channels and a common ground on MATLAB (for it to create a voltage graph.)
I tried importing ai0 and making that single ended, which worked, but then when i tried to import ai1, I got this error:
NI Error -200077:
Requested value is not a supported value for this property. The property value may be invalid because it conflicts with another
property.
Property: DAQmx_AI_Min
Requested Value: -20.0
Valid Values Begin with: -10.0
Valid Values End with: 10.0
Channel Name: Dev1/ai1
Task Name: _unnamedTask<63>
Status Code: -200077
Also, when I tried importing them all at once, but I'm not sure how to make all 3 channels single-ended. Is there another way to do this? OR will it work if I just add the first three channels without making them single-ended but using one ground? Won't the computer assume that ground is ground? Thanks!
