Step 2: Calibrating handpieces or contra angles

To make sure the displayed parameters correspond with the actual, measurable parameters of the
handpiece or contra angle, it is recommended to calibrate each handpiece or contra angle on a regular basis.
It's a procedure as simple as it is important to guarantee safety and precision of each handpiece or contra
angle being used.
After you take care of all prior preparations such as sterilization, maintenance and care of handpieces,
device preparation and the selection of the handpiece of use, the calibration procedure can be performed.
The calibration of handpieces or contra angles guarantees accurate torque. Due to wear as well as varying
lubrication of the handpieces or contra angles, and lack of maintenance and care, the distribution of
torque can vary widely.
1. Select the handpiece, attached to the motor, by pressing the "handpiece" key. Make sure that this
handpiece attached to the motor is also on the display.
2. Hold motor with mounted handpiece or contra angle in your hand at safe distance from your body.
3. Press both "Speed" keys at the same time (Speed ▲ + Speed ▼). Display indicates "Calibrating
handpiece XX".
4. Motor and handpiece start running and pass several speed cycles up to maximum speed.
5. After a tone emitted and a message displayed the calibration is finished. The display returns to normal
mode.
If a handpiece is not working within the range of the calibration algorhythms, even when it was cleaned
and lubricated before, the display shows an error with a red backlit display, „Handpiece XX is faulty".
This indicates soiling, wear or a technical defect of the handpiece. These handpieces have to be repaired
or replaced.
At the calibration procedure, the handpieces are tested on their torque delivery behavior. With the 1:1
Handpiece the control unit is additionally adjusted to altered conditions of the handpiece to keep the 1:1
Handpiece delivering the appropriate torque.
