We're having problems when trying to read two voltages, on different channels at the same time on our ADC Pi. We have a voltage divider set up and can verify that when reading one channel at a time, the voltage is correct. When we attempt to read off two channels we've seen three different things
1) No voltage on the second channel but normal on the first
2) A higher voltage on the first channel and nothing on the second
3) Both channels reporting a voltage but one or both possibly incorrect.
We are using the appropriate voltage multiplier.
