Thickness Measurement with ILD 1700
This chapter describes a comparative thickness measurement using two optical laser
sensors of the series ILD 1700. The display shows the displacement values and the
thickness value (absolute dimension) of each sensor on the CSP2008. The distance of
both laser sensors from each other is not precisely known, see Chap.
5.3.10.6
.
For the thickness measurement, the CSP2008 needs a measurement object of known
thickness (= master value) once at the start of the thickness measurement. Starting from
this, the CSP2008 calculates the distance of both laser sensors of the series ILD 1700
from each other and thus the thickness of the target, see Chap.
5.3.10.3
.
The following description requires that the sensors are connected, the laser activation is
on, the voltage supply at the CSP2008 is switched on and that the CSP is connected via
Ethernet to the network (PC), see Chap.

Loading the parameter set into the CSP2008
Selecting of the parameters. All settings of one measurement procedure are saved by
the CSP2008 within one parameter set.
Load/save settings, see Chap.

.
When the
Browse
button is pressed, the Windows Explorer window is opened to select
the saved configuration file. The path is cached when the selected file in the selection
window is opened. The loading of the selected file is then performed by clicking the
Im-
port setup, see Chap.
5.3.12
button.
The program as well as the settings are now saved in the controller under the prese-
lected Setup No. and the controller operates with the new values after completion of the
loading process. Therefore, no reboot in the controller is also performed.
