26. STATISTICAL QUALITY CONTROL- SQC
< Statistical Quality Control > is a working mode designed to support control of product
packing process. It enables detecting surplus or shortfall of product in a packaging.
If the weighing results are stored in the database, then trend analysis can be carried out and
displayed in a form of a graph.
The software provides the possibility of controlling a batch comprising up to 1000 samples.
Each completed control process is saved to the SQC database, and its results are ready for
previewing at any time. Each series has a determined set of parameters that are stored in
the database: maximum, minimum, standard deviation and average value for each batch,
etc.
SQC control process can be carried out manually (by pressing <PRINT> button for each
measurement) or automatically (automatically carried out record of stable measurements).
The balances feature module for statistical control processes. It is supported by a database
containing list of products with error values (<T2->; <T1->; <T1+> and <T2+>) declared for
each product.
The control process is initiated automatically and completed on controlling a required
quantity of samples. As a user you define how many samples are to be controlled, to do it go
to SQC settings.
After completed control process a final report can be generated and/or printed. Data on a
control is also automatically saved to the Database of SQC Reports.
