15.18. Statistical calculations function (StAt)
This function evaluates from series of measurements (max 500) statistical
parameters of weighting process.
Adding successively measurements to register is automatic and it occur after the
scale is loaded and its indications stabilize.
After each loading printout is made with: number of measurements, result, date
and time (if clock is installed and the function is activated).
For the obtained measurements series the scale evaluates:
- n
-number of samples
- sum x
-sum of all samples
