Problems
Display not steady while
measuring: the measure-
ment result is rather longer
or shorter; numerical display
irregular.
Possible causes
If the connection between the
lip hook and the oral mucosa
is ok?
Is there a blood/saliva over-
blood, liquid?
If there is liquid, scrap on the
tooth surface?
If the endo needle contact the
gums?
Solutions
Make sure the lip hook has
contacted the oral mucosa at a
good position.
root canal, glued to the crown
or the tooth neck, will cause
short-circuit then cause the in-
normal phenomena. Clean the
blood and
the liquid.
Once the endo needle contact
the surface of the root canal
liquid, it will display "OVER"

the needle to the apical root
canal, then the display will be
normal, you can measure the
length
of the root canal correctly.
Clean the tooth surface.
The LCD will display "OVER"
if the endo
needle contact the gums.
