At labview, when I use the daq at block diagram, in the properties is possible to put the range I want it to work, and, is possible to choose -10 to +10 V range, but, is it phisicaly possible with ni usb daq 6009? or I can only use a positive signal? I want to use it with a load cell working with traction and compression and I'm about to buy the voltage amplifier, so, I want to know how to choose it.
thank you !
