measure voltage - analod input

[andrikoscy]

i'm using the DAQ 6221 card..

i want to measure the voltage from the analog input.. and show the measure in a chart

i'm using the attached example..

the problem is tha when i measure the voltage.. in the first time, it measurements are true..(my source has a voltage at 5V) but after it stop at 10V and don't do anything! y?

i tried and changed the mode from differential to RSE.. and i have the same problem..
 
how did i change the mode from differential to RSE?

i doubled click to the Daqmx Create Channel.. and then i changed the mode " input terminal configuration " from differential to RSE
is it true?

thanks a lot!!

No, you simply can't double click the subVI. On the block diagram of your main VI, right click on the Input Terminal Configuration input of the DAQmx Create Channel and select 'Create>Constant'. Change the block diagram constant to RSE.
