Statistical Evaluation of the Data
The printer’s built-in statistics program can process all
values that are computed or weighed and transferred from
an on-line weighing instrument. To use this function,
you must activate the statistics program (
-a3- ) in the
“Statistics Applications” menu (see “Settings”). When the
program is activated, the code shown on the right will
appear each time (approx. 0.5 sec.) to indicate that a
particular value is being read into the statistics memory.
The number of values read into the statistics memory is
displayed.
After you have pressed the key, the values trans-
ferred will be read into the statistics memory. Data transfer
in the manual mode allows you to preselect the specific
values to be transferred by pressing
. In the auto-
matic data transfer mode, all values will be read into the
statistics memory once you have pressed
a single
time.
To print the statistics, press the key. Once the
data has been printed out, the statistics memory will be
cleared and either the time or the date will be displayed.
Configuring the Data Printer for Statistical Evaluation
Any of the following statistical values can be configured in
the “Statistics Applications” menu so that it will be printed
or not printed:
– Number of weighing operations n ( -s3- )
– Mean value x¯ (
-s4-
)
– Standard deviation s (
-s5-
)
– Variation coefficient s
rel
(
-s6-
)
– Sum of the individual values/weights Σ x (
-s7-
)
– Minimum value/weight min (
-s8-
)
– Maximum value/weight max (
-s9-
)
– Difference between the minimum
and the maximum value/weight diff (
-s 10
)
