5-4 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 three 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 standard deviation and coefficient of variation are obtained by the equation below:

Standard deviation=	where Xi is the i-th weight data,
	N is number of data.

Standard deviation

Coefficient of variation (CV)=x 100 (%)
