The output voltage of DAQ become low when computer connected to it

[Alokthakur]

Hey all

I am using Lab view 2015, when I connect cable from DAQ to computer the DAQ voltage automatically become low. As for reference I am attaching picture of the output named "before connection" and "after connection". Kindly help me thank you so much

Hi @Alokthakur,

Can you tell us some more about your system? What is the DAQ device you are using? What voltage are you referring to? How are you scoping? We need a little more information here to be able to assist you properly.

Best,

Respected,

I am using DAQ 6001 and the define voltage level is -10 to 10 V. I am doing humidity sensor interfacing with DAQ.

You said when you plug it into the computer the voltage output goes low. How is this different from what you are expecting to see? How are you configuring the voltage output task in LabVIEW? How are you scoping?
