9.1.1.

Linear characteristic

The normalized result is converted by fixed coefficients determined by

“Lo C”

and

“Hi C”

parameters (when the normalized results is equal 0, then value

“Lo C”

is displayed, and when

the normalized results is equal 1, then value

“Hi C”

is displayed). Expression presented below

shows the manner of result calculation:

× 

"Hi C"

−

"Lo C"

 

"Lo C" ,

where

means the displayed value.

The value of the

“Lo C”

parameter can be higher than the value of

“Hi C”

parameter. In such a case, for an increasing value of input voltage the displayed

value decreases.

Figure. 9.1 Normal („Lo C” < ”Hi C) and inverted („Lo C” > ”Hi C) characteristic

9.1.2.

Square characteristic

The normalized result is squared and further conversion is done as for linear characteristic.

Conversion is made accordingly with the expression:

× 

"Hi C"

−

"Lo C"

"Lo C" ,

where

means the displayed value.
