Signal Quality - MICRO-EPSILON confocalDT IFD2410 Series Operating Instructions Manual

Commissioning
5 The current values, such as exposure time and selected measuring rate, are additionally displayed above the
graphic.
6 Mouseover function. Moving the mouse over the graph, marks curve points or the peak marking with a circle sym-
bol and displays the corresponding intensity. The corresponding x-position in % appears above the graph field.
7 The range of interest can be restricted if ambient light of a certain wavelength (blue, red, IR) causes interference in
the video signal, for example. The value for the "Start of range" must be less than the value for the "End of range".
Value range between 0 and 100 %.
8 The linearized range lies between the gray shades in the diagram and cannot be changed. Only peaks whose mid-
dles lie within this range can be calculated as a measured value. The masked area can be restricted if necessary
and is then limited by an additional light blue shading on the right and left. The peaks remaining in the resulting
range are used for the evaluation.
9 The detection threshold, in relation to the dark corrected signal, is a horizontal straight line corresponding to the
preselected value. It should be just high enough so that no unwanted peaks in the video signal are included in the
evaluation. Aim for the lowest possible threshold to get a good signal-to-noise ratio. The detection threshold should
not be changed if possible.
10 X axis scaling: The diagram shown above can be enlarged (zoomed in on) with the two sliders on the right and
left in the lower entire signal. It can also be moved sideways with the mouse in the middle of the zoom window
(four-sided arrow).

11 The two buttons allow you to switch between the display of the video signal and the measured value.

Signal Quality

A good measurement result can be achieved if the video signal is sufficiently intense. Reducing the measuring rate in-
creases the exposure time for the CCD row and thus improves the measurement quality.
You can switch between three basic settings (Static, Balanced and Dynamic) in the
tion in the chart and system configuration is immediately visible.
