daqboard2000 ranges

Hi,

I am getting familiar with comedi and my daqboard2000. I dont understand the results from the demo program inpn.
I connected channel 8 to 5V and the result for range [-10, 10] is fine (5.18883V). 
My problem is that I dont know why the result for range [0, 10] is 7.59457V.

I think comedi_data_read is ignoring the range parameter (and using always [-10,10]) and comedi_to_phys is using it.
Please, can someone give me some clues?
