where:
X1 In and X2 In – measured value
Y1 Out and Y2 Out – expected value on the output
Y1 Out = a

X2 In + b
5.1.2. Conguration of the analog output
characteristic
The P20 transducer enables the conversion of measured values into
an output signal on the base of the individual linear characteristic of
the analog output. On the base of given by the user coordinates of
two points, the transducer determines (from the system of equations)
coefficients a and b of the individual characteristic.
Fig. 6. Individual characteristic of analog outputs
The X1 In value on the transducer input
=> Y1 Out value on the analog output
The X2 In value on the transducer input
=> Y2 Out value on the analog output
Other points of the characteristic are calculated
