Example 1
An example of the following settings is shown below.
Input voltage and scaling value become as follows.
■
Example 2
An example of the following settings is shown below.
A measured temperature value and scaling value become as follows.
Precautions
When the scaling function is used with the digital clipping function simultaneously, the scale conversion is performed on the
digital operation values after digital clipping. For the digital clipping function, refer to the following.
