(7) Memorize setting; after completing steps 2 - 6 press and hold [Memorize] key until beep is heard. The beep
confirms that the programming is completed. If you hear a short beep when the [Memorize] Key is first pressed
ignore this sound and keep the [Memorize] Key depressed until a long beep is heard.
* Repeat the above steps 2 - 7 to program any one of the 8 available programs.
6-2 Calibration Function
The rotation resistance of a handpiece depends on the handpiece model, condition, and internal wear of the handpiece
gears. This Control Unit incorporates an automatic function to recognize the level of the resistance of the attached
handpiece and Micromotor.
CAUTION
• This equipment is optimized to obtain the highest accuracy at a gear ratio of 1:20 (X-SG20L/SG20) when
using another gear ratio, note that the accuracy decreases with an increase in the ratio relative to 1:20.
• Micro saw handpiece should not be calibrated.
• Calibration should be performed only on NSK handpiece.
(1) Connect the Micromotor to the Control Unit, Attach the
handpiece to the Micromotor. Turn the power 'ON'.
(2) Attach the calibration bur to the handpiece. (Fig. 17)
(3) Press the [Gear Ratio] Key and select the gear ratio of the
handpiece.
(4) Press & hold the [SYSTEM] Key for two seconds initiates the
calibration mode. The LCD displays "CAL 0N-cm."
(5) Torque Calibration (no load): Ensure the calibration bur is
inserted and free to rotate (Fig. 18). Press the [SYSTEM] Key;
after a notification sound the handpiece will illuminate (Optic
Handpiece only) and the bur will slowly rotate. On completion the
motor will stop the calibration cycle will continue to the next test
(Under load).
(6) On the screen "19.6N-cm" is displayed: align and Insert the
Calibration Bur to the Calibration load, Holding the bur vertically
(Fig 19) press the [SYSTEM] key, after a notification sound, the
calibration will automatically start, handpiece will illuminate
(Optic Handpiece only) and the bur will slowly rotate the load
cell, on completion the motor will stop, "donE" is displayed, the
calibration cycle will continue to the speed checks.
* If "FAIL" is displayed the calibration at that point has failed.
Pressing the [SYSTEM] Key returns the failed process back to
the start, a reattempt can be made on that point.
CAUTION
During a process, it is important to hold the Calibration Bur
vertically without applying any forcible power. Making the
Calibration Bur tilt or pressing it may cause a loss in accuracy.
