Advance 4.0
1.6.2 Manual calibration
The instrument can also be calibrated when a power source is not available for
the base unit (the green Power LED is not flashing). For this purpose select the
Calibration icon in the Settings menu (fig. 11), which you can access from the
Toolbar icon.
Place the hand piece in the calibration block holder and press the measurement
switch to activate the calibration procedure. The beeps indicate that the unit
has been calibrated successfully.
Note:
VITA Easyshade Advance 4.0 is pre-calibrated at the factory for the
calibration block that is shipped with the instrument and may only be used
with this calibration block. If you own more than one VITA Easyshade
Advance 4.0, care must be taken not to switch calibration blocks between
VITA Easyshade Advance 4.0 units, which may adversely affect the accuracy
of measurements.
Make sure that the serial number on the hand piece matches the serial
number on the calibration block holder (see section 1.2).
1.6.3 Monitoring the calibration
Due to environmental changes or after repeated use, it may be necessary
to re-calibrate the instrument when performing repeated measurements.
The animated Calibration icon, as shown in figure 12, indicates that
the instrument must be re-calibrated.
Note:
An anti-infection cover that has come into contact
with a patient must not contact the calibration block assembly.
If this occurs, follow the instructions for cleaning and disinfection
of the calibration block assembly in section 11.
If error No. 106 is displayed, the instrument must be re-calibrated.
