sbRIO 9642 voltage measure

[HaiqiBian]

I want use sbRIO 9642 to measure the value of the voltage, I made a program as following. Is there something wrong? Thanks!

One advise.

You should not use Coercion Dot.

Coercion Dots - LabVIEW 2013 Help - National Instruments

"Coercion dots can affect memory usage or overall performance of a VI"

Keep your mind !!

Thanks for your suggestions, I corrected and is there still have the problems?

Thanks!

Hi Bian,

you should know for yourself if there are problems: Either there will be a problem shown in the IDE or you will receive bogus values…

Your BD snippet looks ok, but could get improved by some (auto)cleanup.

Thanks for your comment.

I exactly know that I can find the problems in IDE.

Actually, the problem of the program is that it can't be shown the value of the voltage correctly, so I ask for help here.

Thanks!

Hi Bian,

when you wired your AI0 correctly you should receive correct readings.

What else can we suggest when you don't provide more details?

The detail is simple: we use sbRIO 9642 to read the value of voltage, for example, the voltage of DC generator (0V - 10V), and display on the Labview. We use J7 Analog I/O connector.

Thanks a lot
