7. Configuration of the display

1. Connect the sensor. Select the terminals which are intended for the voltage /
current range of the sensor (see connection of sensors).
2. Set the operating mode with parameter P01 (measuring range and evaluation
characteristics).
3.Set the value to be displayed at max. sensor signal with parameter P02. The unit
then calculates the displayed value as follows:
proportional display
input signal
max. value of the measuring range
This completes the configuration of the display. The unit is ready for operation.
If requested, the following additional functions can be set:
• Decimal point in the display: 0 to 5 places after the comma (parameter P07).
• Offset: basic value which is added to or subtracted from the displayed value
(parameter P17).
• Mean-value generation: the display outputs the mean value of a defined number of
measuring cycles (not the value of the current measuring cycle); (parameter P30).
• Linearisation: The unit internally calculates the graph of the displayed values from
measured values and parameter settings. For special applications you can replace
this graph by a freely defined linearisation graph (to compensate for measuring
errors of sensors or for special applications). To do so replace 10 values of the
graph calculated internally (x values) by 10 freely defined displayed values (y
values). The unit links the points between the y values by straight lines and thus
creates a freely defined graph of the displayed values. Proceed as follows:
a) Parameter setting of the display as described above (1 to 3).
b) Enter up to 10 x values (parameters P41 to P50). The first value (in P41) should
be "0", the last value (in P50) the maximum value of the measuring range.
c) Enter the y values which are to replace the x values (parameters P51 to P60).
d) Then set parameter P16 to the value 1.
