Data Acquisition, Presets
By selecting a measurement mode in the Data Acquisition section, you can switch between the saved configurations
(presets) for various target surfaces and target movement speeds. Selecting a target activates a predefined configuration
of settings that will produce the best results for the material selected.
Data acquisition
Automatic
Recommended for measurements on poorly reflective or dark targets. The mea-
suring rate depends on the reflectance of the target. The measuring rate is typical-
ly in the range of 3 ... 20 Hz.
Fast
Suitable for fast measurements on moving objects and quick distance jumps. The
target movement speed is typically up to 1.6 m/s. The measured values are output
at 20 Hz.
Accurate
Preset for high accuracy and tolerance in the event of distance changes. The
measured values are output at 20 Hz.
Precise
Preset for highest precision. Provides precise distance measurements on highly
reflective targets. The measured values are output at 20 Hz.

ROI Masking
Masking defines the ROI (region of interest) for the distance calculation. This function is used, for example, to suppress
interfering reflections.
