< About statistics >
The batch calculation determines Mean value, Standard deviation (SD) and
Relative standard deviation (RSD), which is the same as coefficient variance
(CV).
Those values are calculated by the built-in processor as follows:

Note
If the mean value is zero “0”, RSD will appear
on display and be printed out as
“
” symbols not as zero “0”.
In addition, when the number of digits of statistical calculation results is
greater, all digits may not be displayed. Refer to “3
