5 Operation Procedure
5 – 1 Calibration function
The rotation resistance of a handpiece depends on the handpiece model, condition, and internal wear of the handpiece
gears� This product has a function to recognize rotational resistance when in use and make corrections so the set
torque and output torque are the same�
NOTICE
● This equipment is optimized to obtain the highest calibration accuracy at a gear ratio of 20:1� For calibration USE
ONLY the 20:1 reduction handpiece listed in “10 – 1 Contra angle handpieces”� Correct calibration cannot be done
if other handpieces are used�
● Microsaw handpiece cannot be calibrated�
● Calibration should be performed only on an NSK handpiece�
● Only speed calibration is performed if the gear ratio is other than 20:1�
● Press the cancel key for 2 seconds to return to the normal screen from calibration mode�
5 – 1 – 1 Calibration preparation
1
Attach the 20:1 reduction handpiece to the motor�
2
Attach the calibration bur to the handpiece�
3
Press (CALIBRATION) for about 2 seconds to
switch to calibration mode�
Abeep will sound and the display will switch to
calibration mode and “CAL-TRQ” is displayed�
