5.4.4 Individual Characteristic
DHB-2xx meters can recalculated the measured value into any value
thanks to the implemented individual characteristic function. The indivi-
dual characteristic rescales the input signal measured according to the
set characteristic. The way of the individual characteristic interaction on
the meter operation has been presented on the fig.10.
Fig. 10. Action of the individual characteristic
The user can introduce maximally twenty linearizing functions by giving
points defining intervals of the given function operation and expected
values for successive points. On the base of given points and corre-
sponding values to them, coefficients a and b of recalibrating straight
lines are calculated. The programming of the individual characteristic
consists on the definition of the number of points which the input fun-
ction will be linearized by. On must remember that the number of linea-
rizing functions is less of one than the number of points. Next, one must
program successive points by giving the measured value (Hn) and the
expected value corresponding to it, – value, which has to be displayed
(Yn). The graphic interpretation of the individual characteristic is pre-
sented on the fig. 11..
