Note: Definition of the mathematical functions is carried out independently for the
main measuring input and for the auxiliary input, and it is available only for the
selected measurement modes (see Table 9).
5.4.1.14
Individual characteristic
The measuring value measured by the N32O meter can be converted by the provided
individual characteristic (separate for the main input and for the auxiliary input). It is
important when using the mathematical functions to pay attention to the order of
operations - the mathematical functions are completed before the individual characteristic,
which should be taken into account when specifying the points coordinates x values. The
user can define up to 31 linearization functions by defining 32 points of the characteristic.
Parameters of the individual characteristic parameters are available from the menu level
and via the interface. Programming client-specific characteristic requires to define the
number of points and then determining their values. Defining points of the individual
characteristic requires to determine the points of the characteristic by providing the X and
Y values of each point. The X value of the point is the measuring value converted by the
mathematical functions (if they are enabled), while Y value specifies the desired value for
the measurement with X value. During a programming, however, the subsequent entered
points should meet the dependence:
X1 < X2 < X3 < … Xn,
where Xn - the last point of the characteristic.
Failure to observe the above dependence will disable the individual characteristic and set
the error flag in the meter status register.
An example of the graphic interpretation of the individual characteristic is shown in the Fig.
