15.20 Statistical calculations function (StAt)
Attention:
Function is available on demand and it replaces other special functions.
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.
Next measurement is made after taking off earlier load.
For the obtained measurements series the scale evaluates:
- n
- number of samples
- sum x
- sum of all samples
