Statistical Evaluation; Of Measured Values - Sartorius YDP20-0CE Installation Et Mode D'emploi

Statistical Evaluation of Measured Values
The printer's built-in statistics program can evaluate all
values transferred from a connected weighing instru-
ment. To use this function, activate the
statistics program (-A3-) in the statistics application
menu (see "Configuration"). When this function
is active, "STAT." is displayed for one-half a second,
together with the total number of values added
to the statistics memory, each time a value is added to
the statistics memory.
Values are added to the statistics program by
pressing the P key. In manual data storage mode,
the current value is added when you press P. The
allows you to select individual values for evaluation. In
automatic data storage mode, once you press
the P key all subsequent values are added to the
statistics memory.
To print statistics, press the U key. Once the data
has been printed, the statistics memory is cleared and
either the time or the date is displayed.
