Hi, I am using a NI USB 6009 DAQ with a Kistler 50g accelerometer and a Kistler 5114 Power supply coupler (+/- 5 v)
On the NI test panel I can not get the signal to zero, it flickers around the -0.5 v. The signal responds to movement of the accelerometer OK.
I have tried new cabling to make sure there is no pinch on the cables and the problem is still there.
I am not sure what the input configuration on the test panel should be ie differential or RSE. Any suggestions? When RSE selected I get a signal hovering around +0.8, Differential -0.5V.
Any ideas what the problem is would be greatfully recieved.
Thanks
