18.11.3. Use of reference mass values in weighing
A bargraph is one of the elements of the workspace area. There are two criteria for
enabling the bargraph:
 setting “bargraph” parameter to YES when
declaring information items for the percent
setup mode
 enabling at least one additional mode
“Checkweighing” or “Dosing” in “BUTTONS”
menu. After enabling at least one of the
modes, it is available in a form of quick
access key on the bottom bar of the display.
Bargraph colours:
− yellow: mass below the acceptance field
− green: mass within the acceptance field
− red: mass above the acceptance field
Bargraph of the checkweighing mode
In checkweighing mode a user has to specify the high and low thresholds expressed in
percents which constitute for the Reference Mass Values.
EXAMPLE
1. Reference mass value = 50.0g
2. Checkweighing thresholds are determined as:
- low threshold: 95%;
- high threshold: 105%
3. The weighing pan of a balance is
loaded with mass 38,6g that is
77,400% of the reference mass value.
The display status for this mass value
is mass deficiency (bargraph colour is
yellow).
Caution;
the tolerance of the low threshold is– 5% to
the reference mass value
4. Mass of weighed load was increased to
51,2g that is 102,4% of the reference
mass value.
The display status for this mass value
is within the acceptable field.
Caution;
the tolerance of the high threshold is + 5% to
the reference mass value whereas the display
indicates + 2,2% thus the indication is
accepted.
