Measurement mode
After having applied power, the following will be displayed on the LCD display:
Fig. 20: Indication in the measurement mode
In the measurement mode the current measurement value and the switching thresholds will be
shown.
Axxxx
The input signal of the sensor is represented as digital value between 0000 and 1024
this value is equivalent to the relative thickness of the material. A possible result may
look like this: 0.5 mm steel A=0300; 1.0 steel A=0590
Lxxx
Lower absolute threshold (0-999)
Uxxx
Upper absolute threshold (0-999)
The relation between material thickness and digital value depends on the sensor selected and is
not exactly linear. The nonlinearity is influenced by the type of material. During "teach-in" the input
amplifier can adopt its amplification factor and this results in a different digital value. Example for
this influence: Material A with thickness 1 mm may show 0400 after "teach-in". Material B with
thickness 1.5 mm may show 0300 as digital value after "teach-in".
Since the display shows the actual measurement value as well as the set switching thresholds, it
can easily be checked whether the thresholds are correctly set.
2-sheet threshold:
The threshold for 2-sheet should be selected such that it is located slightly above the normal
variation range for 1-sheet, but will be significantly exceeded in case of 2-sheet so that 2-sheet will
be securely detected.
0-sheet threshold:
The threshold for 0-sheet should be selected such that it is located slightly below the normal
variation range for 1-sheet, but will be significantly exceeded in case of 0-sheet so that 0-sheet will
be securely detected.
