Hi,
I am dealing with a measurement system that previously used a "RSE" connection to measure certain voltage signals and it worked ok. Now there's a new DAQ (NI USB 6353) and the "differential" connection is used. However the measurements are no more correct.
I know that it would be possible to change the connection method to "RSE" as it used to be by modifying the VI used but in this case that would be difficult since I do not have an easy acces to the DAQ device anymore.
So the question is this:
Is it possible to manually change a "differential" connection to an "RSE" connection just by disconnecting the GND signal cables now used and connect those input ports to the GND ports of the NI USB 6353? Wouldn't this kind of connection practically be the same thing as using "RSE"?
All help is appriciated.
