Automatic SPC Setup
-
The “Automatic SPC Setup” section applies only to the
Statistical Process Control (SPC) option, which is described
in Chapter 8 of this manual. If you are not using SPC in
your application, you can ignore this section.
An “automatic SPC Setup” is one in which you specify
only the type of chart to be used in the SPC operation. It is
the simplest SPC operation, since it requires little or no
SPC knowledge or experience to set up.
When it performs an automatic SPC setup, the CSS
acquires data initially from a number of sample inspections,
organized in subgroups, in order to calculate stable chart
boundaries before displaying charts and data.
To perform this calculation, the software uses the number
of data subgroups that you specify in the “Number of
subgroups” field.
Each subgroup contains the number of individual
inspections (data points) that you specify in the “Number of
inspections per subgroup” field. The CSS uses this number
for both the initial chart boundary calculation and the
subsequent data displays.
-
The short and long SPC setup screens both have two
questions about saving and/or using SPC statistics. The two
fields in this section enable you to set the default answers to
these questions for both screens. The default answers
