6. THE FUNDAMENTAL OPERATING
INSTRUCTIONS OF THE APEX-LOCATOR
For more accurate apex-locator measurement results, please,
follow these rules:
1. Carefully isolate the studied tooth and working file from saliva.
We recommend to use cofferdam, cotton swabs, saliva ejectors;
2. Work only in rubber gloves;
3. Use the file, corresponding to the root canal width in the apical area
(usually ISO 10-20);
4. Do not use unclean or oxygenized files;
5. Use electroconductive gel for root canals (e.g. RC-Prep, Сanal +)
(recommended);
6. Prevent any contact of an instrument with metals in oral cavity
(amalgam restorations, crowns, brackets etc.);
7. Do not touch the working file metallic parts and patient’s mucosa
with wet hands;
8. Provide wet contact of lip clip electrode with cavity.
Attention!!! There is a possibility of measurements accuracy fall-off
in the following cases:
1. Root canal with large apical constriction 
Root canal that has exceptionally
large apical constriction due to a
lesion or incomplete development
cannot be accurately measured; the
measurement results will be less than
the actual length.
Fig.4

14 www.geosoft.ru / en
USER’S GUIDE
2. Root canal with blood, saliva or a chemical solution overflowing
from the opening
If blood, saliva, or a chemical
solution overflows from the opening
of the root canal and contacts gums,
this will result in electrical leakage
and an accurate measurement can
not be obtained. Wait for bleeding to
stop completely. Clean the inside and
opening of the canal thoroughly to
get rid of all blood, saliva and
chemical solutions and then make a measurement.
3. Broken crown
If the crown is broken and a section
of the gingival tissue intrudes into the
cavity surrounding the canal opening,
contact between the gingival tissue
and the file will result in electrical
leakage and an accurate
measurement cannot be obtained. In
this case, build up the tooth with a
suitable material to insulate the gingival tissue.
4. Fractured tooth. Leakage through a branch canal
Fractured tooth will cause electrical
leakage and an accurate
measurement cannot be obtained.
A branch canal will also cause
electrical leakage.
Fig.5
Fig.6
Fig.7

ENDOEST
hotline @ geosoft.ru
5. Retreatment of a root canal, filled with gutta-percha
The gutta-percha must be completely
removed to eliminate its insulating
effect. After removing the gutta-
percha, pass a small file all the way
through apical constriction and then
put a little saline in the canal, but do
not let it overflow the canal opening.
6. Crown or metal prosthesis touching gingival tissue
Accurate measurement cannot be
obtained if the file touches a metal
prosthesis that is touching gingival
tissue. In this case, widen the opening
at the top of the crown so that the file
will not touch the metal prosthesis
before taking a measurement.
7. Cutting debris on tooth. Pulp inside canal
Thoroughly remove all cutting debris
on the tooth. Thoroughly remove all
the pulp inside the canal.
Otherwise an accurate measurement
cannot be obtained.

USER’S GUIDE
8. Caries contacts with gum
In this case, electrical leakage
through the caries infected area to
the gums will make it impossible to
obtain an accurate measurement.
9. Blocked canal
The meter will not move if the canal
is blocked. Open the canal all the way
to the apical constriction to measure
it.
10. Extremely dry canal
If the canal is extremely dry, the
meter will not move until it is quite
close to the apex. In this case, try to
moisten a canal with saline.

7. MAKE READY AND USING
After the device transportation at temperature below +5 С, you
should let it warm up for an hour at room temperature before
switching it on.
7.1. Battery charging
Chargeable Li-Po battery is the “EndoEst” source power. Before the
first device use it is necessary to fully charge the battery.
One may charge the battery from the mains (110-240)V or from the
PC USB-port.
The battery should be charged in the following way:
- Connect the cable for battery charging (7-fig.1) to the device
“EndoEst”. Insert the USB (B) cable plug to the «APEX/CHARGE”
socket (9-fig.2) on the device.
Variant 1. Charging from the
mains:
- Connect the open plug of the
cable for the battery charging to
the USB socket of the charger (8-
fig.1) - see fig.14 and insert the
charger into the standard mains
supply socket (110-240)V.
Variant 2. Charging from the USB-port:
Fig.14

18 www.geosoft.ru / en
USER’S GUIDE
- Connect the open plug of the cable for the battery charging to the PC
USB-port .
Red light (10-fig.2) indicates that battery is being charged. When the
battery is fully charged, indicator changes to yellow-green.
Note: Standard time for the battery charging is about 2,5 hours,
however, it depends on the battery current charge, level of its wear,
temperature.
Operation and charge time of the old battery is shorter than of a new
one. In the case of meaningful reduction of the device operation
duration you should address to the service department to replace the
old battery for a new one.
- Remove the charger plug from the mains socket and disconnect the
cable from the device and PC when the device is charged.
7.2. Indication of the battery current charge level
The device has special 5-level indicator “Battery” (10-fig.3) to show
the battery charge level. Number of the indicator colored segments is
directly proportional to the current level of battery charge (see fig. 15).
When the battery charge is lower than minimally allowable level
(<20%), you should recharge it (see p.7.1).
Fig.15

19
ENDOEST
hotline @ geosoft.ru
Fig.16
Otherwise, when the battery charge falls to the critic level (<10%), the
indicator starts blinking and in some time the device switches off
automatically. You will see indicator “Battery is discharged” on the
display when trying to switch on the device again.
Attention! When discharged, charge the device power supply in time .
Prevent the battery full discharge.
7.3. Switching on of the device and choosing of an operating mode
- Switch on the device and choose one of the five operation modes by
short pressing the button «POWER/MODE» (4– fig.2).
Modes switching is done according to the scheme represented in the

7.4. Checking of apex-locator
- Switch on the device in «АL» mode (see. p.7.3)
- Connect the tester apex-locator (9-fig. 1) to the
control unit, for which insert the tester into the
socket “APEX / CHARGE”, located on the rear side
of the device (9-fig. 2), until it stops.
In this case, the display should show indication, presented in figure
17, accompanied with an intermittent sound signal.
If the readings on the display are out of range from 0.5 ± 0.2, the
device is not suitable for use in the «АL» mode.
To eliminate the cause of the fault, contact customer service center.
- Disconnect the tester apex-locator from the device.
Note: Perform apex-locator validation before the first use of the
device, as well as at any time in the event you doubt the accuracy of
its readings.
7.5. Connecting the cable and electrodes
- Connect the cable “Signal Line” (2-fig.1) to the device “EndoEst”.
Insert the USB (B) cable plug to the «APEX/CHARGE” socket (9-
