Individual characteristics
The measured value can be recalculated by the entered individual characteristic, and the
transducer is equipped with two implemented independent individual characterstics allo-
wing for any recalculation of the indicated distance. All additional functions such as alarms,
analog output and archiving can be triggered by the measured value which is not recalcu-
lated or recalculated according to selected individual characteristic. The number of points
and the values describing the characteristics points are defined in
PAR1
parameter group
for the first individual characteristic and
PAR2
for the second individual characteristic. Con-
figuration of parameters of characteristics can also be done through the communication in-
terface.
The User can determine the number of points of characteristic (up to 32 points) and define
them. However, the User should remember that during programming the subsequent intro-
duced points must meet the following correlation:
X1 < X2 < X3 < … Xn,
where Xn - the last point of characteristic.
Failure to meet this correlation will result in disabling the individual characteristic and set-
ting an error flag in the register of the transduce status.
A graphical interpretation of the individual characteristic function is shown in the example
shown in Fig. 10.
