Detection threshold
Overview
The detection threshold sets the sensitivity of the peak detection algorithm.
Setting the detection threshold
The configured threshold value must be low enough to detect a peak. However, it must
be high enough so that no noise signals are unintentionally evaluated as data.
Peaks that are below the set detection threshold are considered invalid and discarded.
When the threshold is set high, noise and other weak peaks are not detected as peaks.
For a given measuring head, the intensity depends on the reflectivity of the examined
surface, the slope of the surface, the exposure time of the detector, and the lamp
intensity.
Configuration with commands
Command:
THR
(detection threshold)
Example
Input
Action
THR 30
Sets the detection threshold to 30.
THR ?
Returns the current value.
7.3.7
Detection window
Overview
Detection windows are used to select peaks to be included in the measurement.
Detection windows are used to blank out unwanted signals.
Setting the detection window
The detection window function can be switched on and off. If the detection window
function is switched off, the detection window extends over the entire measuring range.
Detection windows can be newly created. Up to 16 detection windows are possible
within the measuring range. In addition, left and right edges of individual detection
windows can be defined. The margins are specified in μm.
Configuration with commands
Commands
•
LMA
(activation and deactivation of the detection window function)
•
DWD
(creation of detection windows, definition of borders)
Example
Input
Action
DWD 0 190.3
200.5 612.4
745 822.4
Defines three detection windows.
