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:
W
=
U
n
×
"Hi C"
−
"Lo C"
"Lo C" ,
where
W
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.

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:
