Sorting a single item into five bands (% setting).
Two decisions can be made relating to the same item, so as to obtain five
different combinations of results.
Example
First parameter and third parameter: impedance
Z
, will be set as follows:
First parameter
Reference value 3.0 k
Ω
Upper limit value 10%
Lower limit value 5%
Third parameter
Reference value 3.0 k
Ω
Upper limit value -5%
Lower limit value -10%
The results of the decisions with these settings are as shown in the following
table:
It is possible to sort the objects under test into five bands according to the
results of the decisions relating to the first and the third parameter. (This
can also be done using the ABS setting.)
Various other possibilities can be used for the settings, according to
requirements.
