Scaling a voltage input range
The scaling settings for voltage inputs from channels A and B can be made using Thermo-
Collector (PC software).
■
What scaling is
The value Y converted from the input voltage level X according to the following equation is
displayed:
Y = aX + b.
Scaling setting means to set gain a and bias b.
For example, if you want to display:
• “0” when the input level is 0 V
• “200” when the input level is 1 V
then the gain and bias should be set as
•
a = 200
•
b = 0.
The resulting equation is
Y = 200X.
When
X is 0, Y is 0. When X is 1, Y is 200.
