N samples N channels measurement problem.

[JRRiquelme]

Hello!

I´m trying to adquire signal from two channels. Just for testing i applied 1V to channel one and 0 V to channel 2.

When i measure them individualy, with the Cont Acq&Graph example i have no problems, but when i read using the Nchan N samples vi i get 1v and 0,3V

What can i be doing wrong?

My code is the following:

Thank you!

Time to have a look at the SPEC of your (probably multiplexing) DAQ device. Look for the settle time error.

Hi JRRiquelme

I first recomend to test your hardware on NI MAX so we can discard a hardware problem.

Here are two links that may help you

If you have another question or if the problem isn't solved, write me.
