Calibrating the burr drive
Calibration is required when the integrated torque control is started, every
time the contra-angle handpiece is changed, and every time the contra-
angle handpiece is lubricated. Recalibration is not necessary when a file
is changed.
The contra-angle handpiece is automatically checked during calibration.
This includes a measurement of motor current at different speeds to
assess the properties of the system.
