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.
An uncalibrated burr instrument is marked with an "n" on the EasyPad
display. The horizontal bar above it shows that the AutoReverse function
is switched on, see "Switching AutoReverse ON/OFF" [ → 84]. If the auto-
reverse function is switched on, the burr drive automatically switches to
counterclockwise rotation when the torque set is reached.
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.
Calibration only with Sirona instruments
✔
Integrated torque control is switched on. The status display

lights up.
✔
The torque is shown on the EasyPad display.
1. Attach the contra-angle handpiece that you wish to use with torque
control to the electric motor.
2. Insert a file in the contra-angle handpiece. This ensures that the file
is taken into account in the measurement.
3. Press and hold the
Endodontics / Purge
key (> 2 s) or press the right
button of the C+ electronic foot control.
A revolving element is shown on the EasyPad display. The burr
drive is ready for calibration.
4. Hold down the foot pedal throughout the duration of the calibration.
The revolving element is still displayed. During calibration,
increasing speeds are set on the motor.
When the burr drive is calibrated, a "c" is displayed on the
