Not able to read on more than one channel, some channels not at all

[nhboy]

I Have a couple questions.

1. I'm new to labview and don't know much about it I can program some and run the system, my problem is I don't really know how this system is setup and if it is setup right. So I'm as basic as they come!.

2. So my problem is that I can't get data out of my DAQ system. Everything seems to be hooked up right the explorer seems to be automation explorer seems to be working right. When I look at basic thermal couple inputs, I can get data it's not scaled right. The data comes in the same on all three channels, when they have different values. It seems simple enough to get information into the system but again being new at this it's tough to know what is right and wrong!

Thanks in advance I need all the help I can get.

Hi

What hardware are you using? Could you maybe share your VI ?

Nate,

soeren questions will be helpful for figuring out your problem. Some troubleshooting steps I would do is to first verify in Measurment & Automation Explorer (MAX) with test panels that each channel works as expected.

Then after that works correctly here is some helpful information for setting up your DAQ application to perform Analog Input. These pages have a lot of great information that will be helpful to refer back to.
