The “Statistics” application

The header is automatically printed when the “M+” key is pressed during a series of
weighings in order to transfer the first measured weight to the statistical system. The header
can also be printed separately by pressing the “Header” function key.
Printing single values
The same additional settings for the statistics are available in this submenu as for the
header (“Plausibility”, “Max n”, “Nom.,+Tol,-Tol”).
Factory setting: “Net” (net weight value for the current weighing operation),
i.e. no specific information is activated for the statistics.
A single value is printed automatically when the “M+” function key is pressed during series
weighing. A single value can also be printed separately by pressing the «F» key.
Printing the result
The second and third page of this submenu can be used to define which additional
statistical information is to be included in the printed results record:
“Max n”: Defined maximum number of samples in the series.
“Nom., +/-Tol”: Defined nominal weight and tolerances.
“>Tol+, <Tol-”: Number of samples outside the upper and lower tolerance
range.
“n”: Number of samples weighed in.
“x”: Mean weight of all samples.
“s” and “s.rel”: Standard deviation as an absolute and percentage value.
Note: These two values are only printed if the statistics contain
at least 3 values, otherwise horizontal dashes appear in place
of the values.
“Min, Max, Diff.”: The smallest and largest recorded weight value in the current
measurement series and the difference between the smallest
and largest weight value.
“Sum”: Total weight of all saved individual weighings.
Factory setting: “n”, “x”, “s” and “s.rel” are activated (in this order).
The printed results record is printed by pressing the «F» key when the result window is
open. If a specific number of samples is defined for a series weighing (“Max n”), the printed
results record is printed automatically as soon as the weight value of the last sample has
been transferred to the statistics.
A sample printout with statistical values can be found in section 6.4.3.
