6. STATISTICAL CALCULATION FUNCTIONS
In addition to printing out weighing values, the printer can also perform statistical calculation of the
weighing values printed out. The printer always performs calculation processing while operating,
so you can print out calculation results at the touch of a key whenever needed.
6-1. Printing example and printing contents of statistical calculation
Printout example
1.
When printing out the weighing values, the weighing
umber is printed out.
If unit and kind of data entered in the printer differ from
those of the data entered first, the printer prints out the
values without calculating.
2. If accidentally printing out the weighing values, press the
key.

is displayed and the
printer does not calculate prior data.
3. When printing out total calculation results, press the
key. Date and time, ID code, data count (N) and
total (TOTAL) are printed out.
4.
When printing out all of the calculation results, press the
key.
Date and time, ID code, data count (N), total (TOTAL),
averaging value (AVE), maximum value (MAX), minimum
value (MIN), maximum value - minimum value (R),
standard deviation (STDEV), coefficient variation (CV) and
minimum weighing value (MINI WT) are printed out.
Coefficient variation
(CV) =

Minimum weighing value (MINI WT) = standard deviation (STDEV)

* Calculation of the minimum weighing value conforms to
USP Chapter 41. This calculation is applied only when
weighing using a weight.
* Data count (N) to be calculated is a maximum of 999.
5. After printing out all of the calculation results, data to be
used at statistical calculation can all be deleted.
