Performing manual measurements with the file clamp

For an endodontic examination, manual measurements can be made
using the file clamp and a root canal file.
ü The treatment center is prepared for manual measurements using
the file clamp, see section "Preparing to use the ApexLocator"
[→ 104].
ü The Start sub-screen is displayed on the touchscreen.
1. Touch the Manual Measurement with File Clamp key.
Ä If this function is activated, the Manual measurement with file
clamp key is highlighted in orange.
Ä The distance display is shown on the touchscreen.
2. If the distance to the apex is to be indicated with an acoustic signal,
press the Apex distance signal tones button.
Ä If the button is colored orange, acoustic signals will be played in
addition to the distance display diagram. The intervals between
the acoustic signals vary according to the measured distance to
the apex.
CAUTION
Preventing incorrect measurements
When performing the apex measurement, wear non-conductive
gloves to avoid measurement errors caused by unwanted leakage
current.
During the measurement, the root canal file must not come into
contact with the patient's mucosa, metallic tooth restorations, or the
mucosal electrode. We recommend the use of a cofferdam for
treatment.
3. Attach a root canal file to the file clamp.
4. Short the electrical measurement system. Hold the clamped files
directly against the mucosal electrode. This cancels out any
inaccuracies caused by jumps in impedance in the measurement
setup (standardization).
Ä If a short signal is heard and the distance display appears with
no bars, standardization was successful. If not, check the
electrical connections for signs of damage.
5. Place the mucosal electrode in the patient's mouth and perform the
measurement.
Ä The measured root canal depth is displayed by a colored bar in
the distance display. For more information, please refer to
"Distance display" [→ 106].
The manual measurement in the Start sub-screen is ended
automatically when you exit the program or display another program.
