4.8 Canal measurement operation
When using in standalone apex locator
mode, we suggest putting the motor
handpiece on the charging base to get
better visual angle.
Press Setting button “P” once during
standby state, press Adjusting button
“+”/“-” to select EAL Operation mode,
then press Main button to confirm. (See
chapter 3.3 Terms and definition to get
the explanations of Operation modes.)
The measuring wire must be connected
with motor handpiece by USB socket,
white socket connects with patient’s lip
by lip hook, and black socket connect
with file clip.
The canal length indicator bar will show
on the screen(more information about
canal length indicator bar, please see
chapter 3. 2 Screen display).
The file clip must hold the file correctly.
Push the button on the file clip with
your thumb in the direction shown by
the arrow. Clip the holder onto the metal
upper part of the file and then release
the button.
Connection testing
It is strongly recommended to test the
connection every time before use. Clip
the holder onto lip hook and check that
all the bars on the meter on the screen
light up, otherwise, the measuring wire
or file clip should be replaced.
Root canals not suitable for canal measurement
Accurate measurement cannot be obtained for the root canal conditions
shown below.
Root canal with a large apical foramen.
Root canal that has an exceptionally
large apical foramen due to a lesion
or incomplete development cannot be
accurately measured. The results may
show shorter measurement than the
actual length.
Root canal with blood overflowing from
the opening.
If blood overflows from the opening
of the root canal and contacts the
gums, this will result in electrical
leakage and an accurate measurement
cannot be obtained. Wait for bleeding
to stop completely. Clean the inside
and opening of the canal throughly to
get rid of all blood, and then make a
measurement.
Root canal with a chemical solution
overflowing from the opening.
An accurate measurement cannot be
obtained if some chemical solution is
overflowing from the canal opening.
In this case, clean the canal and its
opening.
It is important to get rid of any solution
overflowing the opening.
