CALIBRATING THE RECORDER
Before first use, the parameters of the recorder must be adjusted so that they best fit the mandibular
movement sensor in use. It is not necessary to calibrate the device at each use provided a particular
recorder is always used with the same mandibular movement sensor. However, the device must be
recalibrated in case a different mandibular movement sensor is associated with it. Recalibration of
the device can also help solve a problem related to the recording of the Jawac signal (see the chapter
«Troubleshooting»).
Each time a new mandibular movement sensor is associated with the recorder, the device
must be recalibrated��
To calibrate the device:
• Gather the recorder, the mandibular movement sensor which is associated with the recorder, and the
calibration tool provided with the sensor. The probes must be inserted into the holes in the calibration
tool.
• Connect the recorder to the PC.
• Connect the JAWAC (black connector) to the BRIZZY
• Go to the "OPTION" menu of the CERES software.
• Click on 'Calibrate Device'.
• Follow the instructions which appear on the screen.
• Once it has been launched, the calibration process runs automatically. The green indicator light on the
device flashes rapidly during calibration.
The probes must remain fully pushed down into the holes of the calibration tool during the
entire calibration process� If a calibration is started when the probes are not in the proper
position, the mandibular movement measurements will be incorrect� Recalibrate the device
in this case�
During calibration, the calibration tool should stand at a distance of at least 20cm (8») from any metal-
lic object and from any other electronic device (ex: computer). Pay particular attention to the material
(possibly metallic) of the table which is supporting the calibration tool.
