User manual for digital indicator with U/I input SWE-73-A
the normalized results is equal 1, then value
“Hi C”
is displayed). Expression presented below
shows the manner of result calculation:
W
=
I
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 current the displayed
value decreases.
Figure. 9.1 Normal („Lo C” < ”Hi C) and inverted („Lo C” > ”Hi C) characteristic

Square characteristic
The normalized result is squared and further conversion is done as for linear characteristic.
Conversion is made accordingly with the expression:

Square root characteristic
The normalized result is rooted and further conversion is done as for linear characteristic.
Conversion is made accordingly with the expression:
