Verifying Sensor Voltages
Here is an overview of the ADC voltages expected on a new AQ board. Every board has been tested, so this is mostly posted for reference in case of suspected calibration problems.
To check the ADC voltages, mount the board with some standoffs, place it level and make a 30 second log. Then use the log viewer to check each individual value. Allow for around a 10% tolerance on each value, and that the values will vary with temperature and/or other factors, as noted.
The reference values below were taken with the AQ board in a level position, at room temperature (~20C).
