automatic mode uses the entire exposure range of the Laser Line
Probe. In this mode, you may notice a slight decrease in speed as
the Laser Line Probe automatically adjusts from one surface type
to another.
•
Automatic - Highly Reflective
: This is an automatic setting for
use with reflective, or shiny, materials. This automatic mode uses
the lower half of the exposure range of the Laser Line Probe.
•
Automatic - Normal
: This is an automatic setting for use with
non-reflective, or dull, materials. This automatic mode uses the
upper half of the exposure range of the Laser Line Probe.
•
Fixed Exposure
- The Exposure setting is constant.
N
OTE
: The three Automatic settings disable the AUTO button
and ignore the Exposure and Noise Threshold sliders.
Choosing any of the three Automatic settings adds an exposure
indicator to the R
ANGE
F
INDER
dialog box. In the R
ANGE
F
INDER
dialog box:
• A green dot in the upper left-hand corner of the R
ANGE
F
INDER
dialog box indicates that the exposure has been adjusted and
you are ready to scan.
• The indicator changes to either a red “+” (plus)
or “-” (minus) sign indicating that the Laser Line Probe is
either over-exposed or under-exposed, and it is automatically
adjusting the exposure. The Laser Line Probe does not collect
data during this adjustment, however this automatic adjustment
process is very fast.
For more information, see “Range Finder” on page 31.
During the calibration of the Laser Line Probe, this setting
temporarily changes to
Automatic - Normal
except when using
Fixed Exposure
. For more information, see “Calibration” on
• Choose Save As... in the M
ATERIAL
drop-down window to save a
material setting.
In general, the default values for all settings described here will yield
acceptable data on most surfaces. The E
XPOSURE
parameter requires
more frequent adjustments based on the different surface finishes you
are scanning.
