Hi all,
i am having issues getting stable readings from my analog adapter. It is connected tot 2 pressure sensors that are giving values between 0-10V. I have set the adapter up so that it has all 4 inputs set for 0-10V, and have a python script reading the values manually. I have checked the inputs using a digital multimeter and it is giving me reasonably stable and consistent results, but when I run the script, the vaules vary wildly, and I am not sure why, hence, nor how to fix it. Any troubleshooting tips would be welcome.
To show you what I mean about the fluctuating outputs, here is a sample of what I get, even though it should be the same every time I sample.
Cheers,
Tom.
