Once the calibration process is complete, the following message
will be displayed. If Cross-level Rezeroing was initiated manually
by selecting from within the ‘user menu’ then the number displayed
represents the ABSOLUTE offset for Cross-level. If however the
rezeroing was initialised automatically (due to a change in
temperature) then the number displayed represents the ‘adjustment’
made to the previously stored value, thus giving an indication of the
previous offset error.

At the end of the Cross-level Rezeroing process the final value is
checked to ensure it is within certain criteria. If these criteria are
not met then the calibration is aborted and the following message is
displayed. In this instance, the user should attempt to re-zero again
before using the Garnet.
