4.2.4 Operation of Apex Locator
We are committed to producing safe and reliable medical equipment to let doctors handier to use, so we
recommend doctors to use the apex locator control motor mode.
4.2.4.1 Connecting
For
combined apical length measurement
use the contra angle, covered by the silicone sleeve.
Connect the lip clip cable to the Micro USB port at bottom of the central unit. Insert the lip clip
into the connector at the end of the cable. Ensure the connection is solid.
Put the pip clip in the patient’s mouth (we recommend positioning it on the opposite side of the
tooth undergoing therapy).
For
independent apex locator measurement
use the separate file clamp with a manual measuring file
instead of the contra angle.
Connect the Measuring cable for apex locator to the Micro USB port at bottom of the central
unit. Insert the lip clip into one of the connectors, insert the file clamp into another connector.
And ensure both the connection is solid.
Put the lip clip in the patient’s mouth ( on the opposite side of the tooth undergoing therapy)

B
，
Contact with the lip clip and file
，
select the Apex locator
control motor rotation mode
）
Contact the file installed on the Contra angle with the lip hook will cause
the following conditions
：
1)
File will anti-clockwise rotate
2)
The warning will sound rapidly
3)
Display on the screen
：
Root canal indicator scale full grid, the root canal indicator data: “- -”, APEX
non-stop flashing
At this time, it is proved that the measuring circuit is normal, and the next operation can be carried out
