SCB 68 connect to PXI 6228

[SerenityWang]

Hello, 

I connected the SCB 68 with the PXI 6228 using the cable. 

Then I used the labview to read the voltage between two pins. 

The weird thing is that as long as I touched the cable, the voltage in the labview will change dramatically (as shown in the first column, row 1 & row2). I don't know what's wrong. 

Could anybody help me?

Thanks a lot,

Serenity

Sorry. My DAQ is PXI 6229. Sorry for the typo and confusion. 

Let me know if you have any suggestions.
