How to Set the Auto Mode
The Accutome A-Scan Plus allows you to define the
Automatic measurement mode by specifying how a
measurement is automatically captured. There are a
total of three criteria available and each can be turned off
or on by the user on the Setup screen. The criteria are:
Sclera - automatic capture determined by
sclera detection
Retina - automatic capture determined by
retina detection
Stable - automatic capture determined by
measurement stability
The Auto Mode setting is displayed in the soft menu on
the Measure Screen as ‘Auto (SRS), where (SRS)
means Sclera, Retina, Stable. If the feature is ON, the
first letter appears in its place, otherwise a placeholder
‘_’ is displayed.
The default is ’Sclera’, displayed as ‘Auto (S__)’. Sclera
must have a distinct sclera echo after the retina, above
the threshold. Between the Retina and Sclera the signal
must go below the threshold.
’Retina’, displayed as ‘Auto (_R_)’, must begin at the
base line, have no data greater than 10% of the
threshold in front it (for 1.5 mm), and be steeply rising.
"Stable’, displayed as ‘Auto (__S)’, means the
measurement needs to be within a tolerance for a certain
amount of time.
*Note: The Stable Auto Mode setting is not recommended
for contact method measurements. The
measurement variance caused by hand or eye
movements may make the stable auto lock
requirement difficult to achieve.
*Note: Sound, if enabled, reflects the quality of the
measurement with respect to the current auto mode
settings, even if you are using the Manual capture
mode.
