read mV signal

[Fluppebowl]

Hey,

Is it possible to read a AI signal, with a range between 1 mV and 150 mV, with a USB-6210 data aquisition?

How is it done?

Kind regards

You should just go read the specs.  It appears that the minimum range is -200mV to +200mV.  The accuracy at that range i 88uV.  Yep, I would say it can do the job.

Oke,

I also read the specs.

What I don't get :

does the NI USB-6210 need min 200mV input reagardles + or -

or

can it also reed values lower than 200 mV?

-200mV to +200mV is a range.  The DAQ will measure a voltage within that range.  If you need to measure something outside of that range, you need to select the next higher range.  Since you are talking 150mV for you maximum voltage, the 200mV range is perfect.
