5.4.4 Individual Characteristic
DHB-1xx meters can recount the measured value into any value thanks
to the implemented individual characteristic function. The individual
characteristic causes rescale of the measured value for the expected
indication range vaule. The way of the individual characteristic interac-
tion on the meter operation has been presented on the fig.10.
Fig. 10. Action of the Individual Characteristic
The user can introduce maximally twenty functions through the given
points defining intervals with expected values (fig.11).
The programming of the individual characteristic consists in the defini-
tion of the number of points which the input function will be linearized
by. One must remember, that the number of linearizing functions is of
one less than the number of points. Next, one must program successive
points by giving the measured value (Hi) and the expected value corre-
sponding to it, – value which has to be displayed (Yi) (where i – number
of the successive point, 0 < i < n).
The graphic interpretation of the individual characteristic is presented
on the fig. 11.
