a) I
in
=10 mA and I
n
= 0,375
Accordingly to expression on page 24 for linear characteristic:
0,375 × [1200 -(- 300)]
≅
562 and next, the
“Lo C”
value is added to the result , so the
displayed value:
W
≅
562 + (-300) = 262
b) I
in
= 2,5 mA and
I
n
= -0,0938.
W
≅
-441.
c) I
in
= 20,5 mA and
I
n
= 1,0313.
W
≅
1247.
Example 4: The square characteristic
Let parameters
“Lo C”
and
“Hi C”
equal to -300 and 1200 respectively. The calculations will
be done for there different input currents from example 2.
a) I
in
=10 mA and I
n
= 0,375
Accordingly to expression on page 24 for square characteristic: (0,375)
2
× [1200 -(- 300)]
≅
211.
and next, the
“Lo C”
value is added to the result , so the displayed value:
W
≅
211 + (-300) = -89
b) I
in
= 2,5 mA and
I
n
= -0,0938.
W
≅
-287.
c) I
in
= 20,5 mA and
I
n
= 1,0313.
W
≅
1295.
Example 5: The square root characteristic
Let parameters
“Lo C”
and
“Hi C”
equal to -300 and 1200 respectively. The calculations will
be done for there different input currents from example 2.
a) I
in
=10 mA and I
n
= 0,375
Accordingly to expression on page 25 for square root characteristic:
0,375
× [1200 -(- 300)]
≅
919.
and next, the
“Lo C”
value is added to the result , so the displayed value:
W
≅
919 + (-300) = 619
b) I
in
= 2,5 mA and I
n
= -0,0938 , normalized result is negative , so the displayed value is equal
to
“Lo C”
parameter: W
≅
“Lo C”
= -300.
c) I
in
= 20,5 mA and I
n
= 1,0313.
W
≅
1223.
