AI sense channel on USB 6008

[zhou15]

Hi,

I'm usin NI USB 6008 to collect the force/torque sensor data (6 channels) from its conditioning DAQ interface. Due to my DAQ USB 6008 only have only 4 differential channels. I have to use it in the single ended conneciton. I connected the device to the daq according to this diagrham provided by the sensor company.  

My question is how could I substiute/ make a channel to serve as Anallog Inpu Sense?   If I use the AI GND instead, I observed signal saturaion on SG0, SG3, SG4 channels.  

Please help me if you could. Thanks in advance!

Sorry, I cannot really help, but I remember I had often troubles with single ended connections. I would recommend to use 2 USB-6008 or a single NI device equipped with 8 differential inputs, like the USB-6210.

Alternatively, you could contact an NI engineer for help/recommendation for your actual setup.
