■
The meter’s 0.5 reading indicates that the tip of the file is in
or very near the apical constriction.
* The numerals on the meter gauge do not represent
millimeters.
■
If the file tip reaches the apical foramen, a single, sustained
beep will sound, and the word "APEX" and the little
triangle next to the Flash Bar will start to flash on and off.
Operating the Unit
1. Turn the unit on.
2. Hook the contrary electrode in the corner of the patient's
mouth.
WARNI N G
• Do not use an ultrasonic scaler with the contrary electrode
attached to the patient.
Electrical noise from the scaler could interfere with canal
measurements.
• Make sure that the contrary electrode, file holder etc. do
not come into contact with an electric power source such
as an electrical socket. This could result in a severe
electrical shock.
NOTE
• The contrary electrode could cause an adverse reaction if
the patient has an allergy to metals. Ask the patient
about this before using the contrary electrode.
• Take care that medicinal solutions such as formalin cresol
(FC) or sodium hypochlorite do not get on the contrary
electrode or the file holder. These could cause an adverse
reaction such as inflammation.
