OPERATION CONTINUED
The statistical quality control (SQC) feature is useful during
various types of process filling operations, to monitor and/
or control the process to eliminate under- and over-filling.
As samples are weighed and stored in the balance, a
trend analysis is developed and can be displayed.
Up to 10 batches with up to 80 samples in a batch
are visible for quality control purposes. Each batch of
samples is shown, with the maximum, minimum, standard
deviation and mean values for each batch. An ongoing
examination of the relative deviation of the samples
along with other statistical data can be viewed.
The filling process operation can be effectively monitored
by observing the results on the view trace screen.
SQC collection can be done manually (manual mode,
requires key press after each step) or automatically
(auto mode, the weights are automatically recorded
when stable).
In the upper left portion of the home screen, select SQC.
