2.2.2 Torque Display
This appears when the motor is running. Meter shows the torque load
on the file.
2.2.3 Canal Measurement Display
This appears when a file is inside the canal and the lip hook is
contacting the patient mouth. Bars in meter show the location of the file
tip.
The meter numbers 1.0, 2.0, 3.0 and digital numbers 00-16 do not
represent the actual length from the apical foramen. It simply indicates
the file progression towards the apex. The digital numbers -1 and -2
indicate that the file has passed the apex foramen. The digital number “00”
indicate that the file has reached the apex foramen. Subtract 0.5-1mm
from the measured file length as the working length. These numbers are
used to estimate the canal’s working length.
2.3 Instructions for contra angle
2.3.1 The contra angle adopts precision gear transmission, and the
transmission ratio is 6:1.
2.3.2 Before the first use and after treatments, please clean and
disinfect contra angle with disinfectant of neutral PH value. After
disinfection, lubricate it with specific cleaning oil. Finally, sterilize
it under high temperature and high pressure (134℃, 2.0bar~2.3bar
(0.20MPa~0.23MPa)).
2.3.3 The contra angle can only be used cooperatively with this
