I am working on a simple temperature data logging with USB-6210. I am getting unstable temperature reading on my chart only on AI0, other 7 temperature channel is fine. The temperature temperature fluctuation on AI0 is as much as 40 C. on other channel it's only 2~3 C, which is fine.
Taking the measurement using multimeter from ground to AI0 showing consistent reading, No fluctuation. I tried other channel as well AI15 as such. same results. Anybody has explation?
Excuse my english
