5.1 Example of Comparator Application
Making decisions for two items simultaneously (ABS and % settings).
Example
First parameter: static capacitance Cp and third parameter: phase angle
θ
will be set as follows:
First parameter (ABS setting)
Upper limit value 110 nF
Lower limit value 100 nF
Third parameter (% setting)
Reference value -85
Upper limit value 5% (i.e., -80.75 )
Lower limit value -5% (i.e., -89.25 )
The results of the decisions with these settings are as shown in the following
table:
Comparator decisions
In this manner, two decisions can be made simultaneously. Further, it is
possible to check the decision results for two different parameters at the
same time, and thereby to determine what quality zone the object which is
being tested falls into.
