14.23 Calculator for good packaging control (tP)
Note:
This function is enable for special orders substitutable
with other functions.
The function allows performing not destroying control of 60, 100 or 160 samples of packed
goods. Calculation formula complies with the description of reference method described in act of
law from 26.07.2001 (with later changes).
Scale operator enters nominal net mass (Qn) and sample quantity taken for control (quantity
refers to total quantity of samples 1 and 2 in description of reference method.
Accepting successive measured packages (storing in register) is performed automatically after
load is put on and scale indication is stable.
Each time after load is put on printout is performed: measurement number, result, date and hour.
Accepting next measurement is possible after taking last load off.
For obtained measurement series scale calculates:
-
x
-average mass as (sum x)/n
- Min
-minimal mass in n samples
- Max
-maximal mass in n samples
- R = Max-Min
-the difference between max and min
- S
-standard deviation
