Performing manual measurements with the file clamp
For endodontic examination, a manual measurement can be performed
using the file clamp and a root canal file.
✔ The treatment center is prepared for manual measurements using
the file clamp, see section "Preparing to use the ApexLocator"
[ → 121].
✔ The Start sub-screen is displayed on the touchscreen.
1. Touch the
Manual Measurement with File Clamp key.
 If this function is activated, the
Manual measurement with file
clamp
key is highlighted in orange.
 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.
 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.
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. For more information, please refer to
"Distance display" [ → 123].
The manual measurement in the
Start sub-screen is ended automatically
if you exit the program or display another program.

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.
