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
