7.2 Quick precision check
• E.g.; after dropping down (crashing) of the unit.
Periodically perform a quick check to ensure the precision of
the device. Place the BB upside down and turn the unit by
means of the power cord. The magnetic base should not
have more than 0,025mm variance in the height. Figure 28
