Instructions for Use 2019-03-20
If the equipment does not seem to be working properly, the user should first try to inspect and adjust it himself.
* If the user is unable to inspect the device themself or if the device fails to work properly after being adjusted or
after parts are replaced, contact Poldent Co. Ltd.
Does not turn on.
• Check battery installation.
• Install batteries properly.
• Check battery power.
• Replace batteries.
Cannot make a
Measurement.
• Check cord connections.
• Check that all connections are properly secured.
• Check probe cord for broken wire.
• Touch the contrary electrode to the file holder to check
probe cord conductivity.
No alarm sound.
• Check if the sound volume is set to
“OFF”.
• Set it to “Soft” or “Loud”.
Cannot switch memo-
ries.
Cannot change
memory settings.
• Is a measurement being performed?
• The memory cannot be changed while the device is
making a measurement.
• Does the Set Switch work?
• The Set Switch may be broken. Contact Poldent Co.
Ltd.
Display does not ap-
pear.
• Try replacing batteries.
• If new batteries do not solve the problem, the LCD
may be malfunctioning. Contact Poldent Co. Ltd.
Canal Length Indica-
tor is unstable.
• Is contrary electrode making good
contact with oral mucosa?
• Make sure the contrary electrode makes good contact
with the oral mucosa.
• Is the file holder dirty?
• Clean the file holder with ethanol (70 vol% to 80
vol%).
Canal Length Indica-
tor overreacts or is
too sensitive.
(Measurements are
too short. Poor accu-
racy. Erratic results.)
• Is blood or saliva overflowing from the
opening of the crown?
• If blood or other fluids overflow the canal, the current
will leak to the gums and the meter will jump to the
APEX. Clean the canal, canal opening, and tooth crown
thoroughly.
• Is the canal filled with blood, saliva or
chemical solutions?
• The canal length indicator bar may suddenly swing
when it breaks the surface of fluids inside the canal,
but it will return to normal as the file is advanced down
toward the apex.
• Is the tooth surface covered with cut-
ting debris or chemical solutions?
• Clean entire tooth surface.
• Is the file touching the gingival tissue?
• This will cause the canal length indicator bar to sud-
denly jump all the way to the APEX.
• Is there pulp tissue left inside the root
canal?
• Accurate measurements cannot be obtained if a large
amount of pulp tissue is left inside the root canal.
• Is the file touching a metal prosthesis? • Touching a metal prosthesis with the file allows a flow
of current to the gingival tissue or periodontal pocket
and will cause the meter to jump to the APEX.
• Are proximal surfaces infected with
caries?
• Current can flow through the caries infected area to
the gums and prevent an accurate measurement from
being made.
