6.6. Statistical Calculation Mode
The statistical calculation mode statistically calculates the weight data, and displays or outputs the
results. To use the statistical calculation mode, set the "Application function (
apf
)" parameter of
“Application (
ap fnc
)” in the function table to “
2
”, as described below.
Statistical items available are number of data, sum, maximum, minimum, range (maximum-minimum),
average, standard deviation and coefficient of variation. What statistical items to output can be
selected from the four modes in the function table.

The wrong data input can be canceled by the key operation, if immediately after the input.

Turning the balance off will delete the statistical data. (The ON:OFF key will not initialize the
balance.)

The standard deviation and coefficient of variation are obtained by the equation below:
Standard deviation=
Standard deviation
Coefficient of variation (CV)=
Average
Maximum value - Average
Relative error of maximum value =
Average
Minimum value - Average
Relative error of minimum value =
Average
