Meter Display
■ The position of the file tip is shown by the canal length
indicator bar on the display. The apical line flashes on and off
once file is inserted into the root canal.

Do not let the file touch the gums. This will cause the
meter to jump to Apex.

If the canal is extremely dry, the meter may not move until
it is quite close to the apex.
If the meter does not move, try moistening the canal with
oxydol or saline.

Occasionally the canal length indicator bar will make a
sudden and large movement as soon as the file is inserted
into the root canal, but it will return to normal as the file is
advanced down towards the apex.

In some cases such as a blocked canal, a measurement
cannot be made. (For details, see “Root Canals not
suitable for Electronic Measurement” on page 13.)

Always check the measurement with an X-ray. In some
cases, an accurate measurement cannot be made
because of the canal shape, unusual cases, or poor
performance of the instrument.

Stop using the instrument immediately if you sense
something odd or abnormal while taking a
measurement.
■ 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 major foramen, the alarm sound will
sustain beep, and the word "APEX" and the little triangle next
to the apical line will start to flash.
