To show the motor speed again when the burr drive isremoved, the Endo function must first be switched off.Purge➢ Press theEndo / Purge key briefly (< 1 s).Ä TheEndo function status display goes out. When the burr driveis removed from the holder, the speed of the motor is shown onthe EasyPad display.4.4.9.2 Calibrating the burr driveCalibration is required when the integrated torque control is started,every time the contra-angle handpiece is changed, and every time thecontra-angle handpiece is lubricated. Recalibration is not necessarywhen a file is changed./An uncalibrated bur is marked with an "n" on the EasyPad display. Thebar above it indicates that the AutoReverse function is switched on, see"Switching the AutoReverse function on/off". If the auto-reverse functionis switched on, the burr drive automatically switches tocounterclockwise 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 toassess the properties of the system.CAUTIONTo ensure proper calibration, use only Dentsply Sirona instruments.ü Integrated torque control is switched on. The status displaytorquecontrol lights up.ü The torque is shown on the EasyPad display.1. Attach the contra-angle handpiece that you wish to use with torquecontrol to the electric motor.
