2. Invert the accelerometer so that the axis being calibrated is now pointing
downwards and measure the output again (-1 G applied).
3. Subtract the second value from the first and divide by 2 and that gives the
accelerometer output for 1 G of acceleration which can be saved as the
calibration value.
The user interface takes you through these 3 steps. At each step, a dialog box
appears telling you what to do. It's very easy.

Various aspects of the PB-4's behaviour can be configured via a set of
configuration values.
• To read the current value, enter the value's name in the Name text input box
followed by the enter or accept key and the value will be fetched from the
