Typically when the zero value is off and the hardware has not changed, it’s because
the temperature of the bolt has changed. In this case, the zero value should not be
changed, but the temperature value should be. Therefore the bolt becomes sort of a
temperature sensor in itself. This is also a good way to monitor temperature changes
in the bolt. The procedures below demonstrate how to adjust the temperature to
match the zero value.
