< 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:

You can choose from Yes or No to print the statistical data:
x Off : No printout
x On : Print the results list
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 “3-6. Batch processing of
titration data” in the operation manual how to operate.
