3. Attach the previously selected file to the handpiece.
4. Short the electrical measurement system. Plug in the files and hold
them 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
treatment. Activate the burr instrument using the foot switch.
The measured root canal depth is displayed by a colored bar in
the distance display. For more information, please refer to
"Distance display" [ → 96].
IMPORTANT
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 instrument must not come into contact
with the patient's mucosa or the mucosal electrode. It is recommended
to pull the protective silicon sleeve over the handpiece and perform the
treatment using a cofferdam.
