4.5.9.4
For endodontic examination, a manual measurement can be performed
using the file clamp and a root canal file.

The dental treatment unit is prepared for manual measurements
using the file clamp, see section "Preparing to use the ApexLocator"

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. It is recommended to use a cofferdam when measuring.
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 skips in impedance in the measurement
setup (standardization).
 If a short signal is heard and the distance display appears with no
bars, the 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.
 The measured root canal depth is displayed by a colored bar in
the distance display. The maximum root canal depth reached is
displayed by a black triangle next to the distance display. For
more information, please refer to "Distance display" [ → 97].
