1.2 Description of the device

Apex locator is a supporting equipment of endodontic treatment, through the

measurement of the length of apical teeth, helping dentists to nish the endodontic

treatment.

Features of the device:

a) Clear image and dierent colors indicate the trajectory of the le clearly.

b) Based on advanced multiple frequency network impedance measurement

technology and automatic calibrating ensures the measurements are accurate.

c) The File clip, Lip hook and Touch probe can be autoclaved under high temperature

and high pressure, avoiding cross infection eectively.

d) Battery is rechargeable, unnecessary to replace batteries repeatedly.

apex.

1.9.6 Operation condition

b) Relative humidity: 30% ～75%

c) Atmosphere pressure: 70kPa～106kPa

2 Notice of installing and using the device

2.1 Please read the instruction manual carefully before the operation.

2.2 As a safety precaution in order to avoid over-instrumentation, it is recommended

to proceed as follows: place the le onto an endodontic ruler, where the apex locator

screen indicates ‘00’. Subtract 0.5-1 mm from the measured file length as the

Working Length.

2.3 The scale indication on the apex locator screen does not represent a distinct

length or distance in mm or other linear units. It simply indicates the touch probe

progression towards the apex foramen.

2.4 If the screen bar graph suddenly makes a large movement or immediate display

‘OVER’ in the upper part of the canal, continue slightly towards the apex so the

signal returns to normal.

2.5 In order to prevent leakage or interference between the root canal and resulting

in inaccurate measurements, dry the access cavity with a cotton pellet or air-blower

before each use.

2.6 Use a le size adapted to the root canal diameter. The selected le is too small

for a large root canal might cause the screen digital display is not steady during the

procedure.

2.7 In order to conrm the le clip and measuring wire makes good contact, test the

wire connecting before each use(See 3.1.3).

2.8 The le clip, lip hook and touch probe are reusable. Please make sure they are

autoclaved under high pressure and high temperature before each operation. The

endo les should not be used more than 3 times.

2.10 When the battery is low, a battery indicator " " appears on the status bar

of the screen. Please recharge the battery when the battery charging prompt icon is

blinking.

2.11 Please use original components, the components made by other companies may

cause inaccurate measurement or un-measurable.

2.12 Avoid the connection between the outside and inside liquid of endodontic during

measuring in order to avoid the measuring dierence.

2.13 Keep endo le and le clip away from any other metal or instruments.

2.14 To ensure that short circuits do not impair the measurements, be particularly

careful with patients tted with metal crowns or bridges. Please conrm the wetness

of the endo to ensure the reliability of the measuring. If it is conrmed that the endo

le hasn't reached the apex yet the data showed on the apex locator is too low, please

check whether the endo is too dry and conrm it with X-ray.

2.15 This device have electromagnetic interference, the patient or doctor who with

a heart pace maker are forbidden to use this device and the device is susceptible

to other device which produces electromagnetic interference. Dentists should be

cautious about operation under such environment.

2.16 The guarantee is valid for normal usage conditions. Any disassembly will render

the guarantee void, the professionals of Woodpecker company will oer the repair

service during guarantee period.

2.17 Any modification will render the guarantee void and may cause harm to the

patient.
