Turn on the Apex ID prior to use.
Plug the Checker [Fig 1-9] (provided in the original packaging)
into the probe cord jack [Fig 2-5] and confirm the value on
the LCD screen is 0.5.
It is recommended to insert the file into the canal first and
then connect the file to the file holder.
If the signals do not change as the file approaches the
APEX, it is possible the root canal is too dry; therefore it
should be filled with saline.
Necrotic tissue or other matter in the root canal may affect
accuracy. It is advisable to take several measurements
during enlargement of the canal.
Start with a larger file at first. If the APEX indication (graph
and numeric signal on the screen) does not reach the
APEX, gradually try a smaller file to measure the working
length of the root canal.

7.1 – Sterilization
The 'Lip Hook' and 'File holder A' should be sterilized at
121°C for 30 minutes with high-pressure steam.
The 'File holder B' should be sterilized at a temperature
of 121°C for 30 minutes with high-pressure steam in a
sterilization pouch, then dried at least 10 minutes after
sterilization.

To minimize error, it is recommended the working length
be measured more than twice.
If root canals within a tooth are connected, as in the case
of multiple root canals with anastomoses or cracks, miss-
measurement is possible. It is recommended to verify the
tooth's anatomy radiographically.
Contact with metal restorations by the file during
measurements may result in errors.
Remove blood or exudate from the canal before
measurement.
In cases where the foramen is not completely formed or
the foramen has been overly expanded, the measurement
value of the working length may be shorter than the actual
measurement value.
7.3 – Method used to validate recommended
sterilization method:
Sterility Assurance Level (SAL): 10
1) Sterilization validation samples are wrapped with BIs.
2) 3 times of sterilization cycles as a half cycle are carried
out at 121°C for 15 minutes.
3) 1 time of sterilization cycle as a full cycle is carried out
at 121°C for 30 minutes.
4) Incubate BIs at 55~60°C for 7days.
