a) U
in
=37.5 mV and U
n
= 0.375
Accordingly to expression on page 34 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) U
in
= -9.38 mV and U
n
= -0.0938.
W
@
-441.
c) U
in
= 103.13 mV and U
n
= 1.0313.
W
@
1247.
Example 4: The square characteristic
Let the input mode = 0-100 mV, and parameters
“Lo C”
and
“Hi C”
equal to -300 and 1200
respectively. The calculations will be done for there different input voltages from example 2.
a) U
in
=37.5 mV and U
n
= 0.375
Accordingly to expression on page 34 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) U
in
= -9.38 mV and U
n
= -0.0938.
W
@
-287.
c) U
in
= 103.13 mV and U
n
= 1.0313.
W
@
1295.
Example 5: The square root characteristic
Let the input mode = 0-100 mV, and parameters
“Lo C”
and
“Hi C”
equal to -300 and 1200
respectively. The calculations will be done for there different input voltages from example 2.
a) U
in
=37.5 mV and U
n
= 0.375
Accordingly to expression on page 35 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) U
in
= -9.38 mV and U
n
= -0.0938. , normalized result is negative , so the displayed value
is equal to
“Lo C”
parameter: W
@
“Lo C”
= -300.
c) U
in
= 103.13 mV and U
n
= 1.0313.
W
@
1223.
