5.5.3. Individual characteristic of analog outputs
The P18(D) transducers in the version with analog outputs
enable the conversion of measured values into an output signal ba-
sed on the strength of individual linear characteristic of analog outputs.
On the base of given coordinates of two points by the user, the trans-
ducer determines (from the system of equations) coefficients a and b
of the individual characteristic.
Y1out = a

X1in + b
Y2out = a


where:
X1 in and X2 in - displayed value,
Y1 out and Y2 out - oexpected value of the analog output
Fig. 11. Individual characteristic of analog output
(T, RH, DP, AH, wet bulb temperature). The value controlling the analog
outputs is defined by the registers, respectively 4015 for the first output
and 4016 for the second analog output (Tab. 14).
