System parameter 4: Selecting the dimensions for the display (mm / inch).
If the measurement dimensions are changed, then the sheet metal thicknesses of the stored
programs parameter are converted into the new dimension.

Fig. 54: Adjusting the measuring mode
Possible measurement modes:
• External continuous measurement:
The system executes measurements, as long as the "Measurement start" signal is applied
via the external PLC input. For FE material the repetition time of the measurement is
0.5 seconds; for NF and LM it is less than 0.085 seconds.
External single measuring:
•
The system measures once if the "Measurement start" signal is applied via the external PLC
input. Each measurement must initiated separately. The hints in chapter 6.1.3.1 „timing
diagram single measurement" must be abided by.
• Demo mode:
This mode of operation is intended for equipment demonstrations but not for the normal
process operation. The system executes measurements continuously. For FE material the
repetition time of the measurement is 1 second; for NF and LM it is less than 0.085 seconds.
System parameter 6: Selecting the speed of measurement.

measure:fast
Fig. 55: Selecting the speed of measurement
Possible choices:
• FE Measurement normal:
With this kind of measuring the system reaction time depends on the measured sheet
thickness. The maximum can be inferred from the diagrams in the chapter 2.2 "Sensor data".
• FE Measurement fast:
Here the system can detect whether double sheet metal is in front of the sensor before the
"normal" end of the measurement. The system reaction time is shorter, depending on the
adjusted nominal thickness as well as the upper limit value.
Disadvantage: In case of measuring results larger than the double sheet threshold, a
double sheet.
For NF and LM (slightly magnetic NF) the exact measuring value is always output.
