[New USB1608G questions]

Thanks. Shorting the inputs does give zero VDC. The problem was my source, which was not low impedance. A different source worked fine.

So, how do I access the "channel-gain queue"?

Thanks again,

[New USB1608G questions]

Hi,

I have set up a new USB1608G connected to a Linux computer. I reached the point where I can run the example program AIn. The numbers I see, however, aren't what I expect. When the input is about zero (VDC), the display reads around 8-9 VDC. I have experimented with single-ended and differential inputs but the results are about the same. Any advice? Is this a faulty device?

I find in the manual a reference to "channel-gain queue" but no information on where this is. Is this relevant to my issue above? How is it created or modified?

I look forward to your response. Thanks....
