Hi All,
I am trying to get a dual forceplate experimental set-up up and running, but I am having a few teething issues (having never done this before), so I wondered if anyone on here might be familiar with the below equipment, and be able to offer some help. I am using:
2 Kistler Z17097 plates
2 Kistler 9865E amplifiers
1 National Instruments USB-6229 DAQ box
The analogue outputs from the two amplifiers are running into analogue inputs 0:31 of the DAQ, in signal/ground pairs for differential readings. The problem I am having is that first one amp, and now the other, have started to give out a constant signal from the first analogue output (A0, which should be Fx 1,2 from the plates). I get a constant reading of 10.7 (I assume thats voltage) from channel 0 on both amps when testing the setup with the National Instruments Measurement and Automation tool.
I can't work out whether something has blown in the amp (both amps, which would be bad) itself, or I have something set-up wrong. Is this problem, or one like it, something anyone else has encountered?
Many thanks,
