analyzing multiple signals, LabView 7.1

[salahnajm]

I'm trying to analyze different signals (oxygen levels, CO2 levels, pressures...)  from my DAQ where each channel has its own graphical and numerical indicator. I tried spitting the signal which seems to be doing it well for the first three signals. The forth signal, for some reason seems to be affected by my third signal and I can't get it to sample independently. That is, when the third signal (voltage reading) goes up or down the forth also goes up and down with it.

It seems that the same thing happens if I want to add more signals (the last one merges with the one prior). It seems like a simple thing to fix but I searched for many days and couldnt find anything. Am I splitting the signals right? How do I make sure each graph and numerical indicator has an indepedent channel?

I attached the diagram I have setup (I know it probably doesnt look professional but that's the best I could achieve 😉 )

I'm using LabView 7.1 with BC-2110 DAQ and have multiple voltage channels that I need to setup (5-6 channels)

Thanks

The BNC-2110 is not a DAQ device at all and attaching an image of a DAQ Assistant does not help because all of the DAQ setting are hidden. Please provide the actual DAQ card you are using with the physical connections as well as the actual VI.

It does not sound like a software problem but a problem with a connection. An open channel will float to the same potential as an adjacent one. Run the test panel in MAX and test each one separately.
