Invalid readings with additional inputs

[jackm]

I am using a PCI-MIO-16E-4 daq. I have three 0-100 mV input channels and three 0-10V inputs. If the 0-10V channels are read simultaneously with 0-100mV channels, the 0-100mV inputs are incorrect. Is this a common problem? How do I fix it?

It seems that the gain setting is not set right.

For the channels that are 0-100 mv, set the gain to min=0, max=100mV
and
for the 0 to 10 v, set it to min=0, max=10 volts

There could be issues (with settling time)at high scan rates when the gains are set differently, but for most part, it should work.
