6.4.2 Weighing to a nominal value
The “Statistics” application offers additional functions, which simplify weighing in to a defined Nominal value. These functions can be
used for both individual weighing and series weighing when using the statistics.
Presettings
The function keys opposite must be activated so that a nominal weight and the correspond-
ing tolerances can be entered (section 6.3.2). To view the defined values in the display, the
information fields of the same name can also be activated, if necessary (section 6.3.3).
Operating sequence
Note: If values are already present in the statistics, the function keys for entering the
nominal weight and tolerances are inactive. If this is the case, the statistics must be de-
leted using the “CL Result” function key, before the nominal weight and the tolerances
can be defined.
Press the “Nominal” function key to enter the desired nominal weight. Type in the desired
nominal weight (if a weight that is already on the balance corresponds to the nominal
weight, this can be transferred directly by pressing the button with the balance icon).
Check the weighing unit, which is displayed to the right of the nominal value. When the
weighing unit is touched a selection box appears, which contains the available units.
Note: The units are not converted automatically, i.e. if you have entered a value in one
unit, this value remains the same even if the weighing unit is changed.
Once you have entered the value, press “OK” to activate the nominal weight.
The “+Tolerance” and “-Tolerance” function keys can be used to specify the precision to
be used for the weighing. The input window is the same as for the nominal value. Both
tolerance values are set to 2.5 % ex works. Instead of a percentage value, you can also
enter an absolute tolerance in any weighing unit. Once you have entered the relevant value,
press “OK” to activate the tolerance. Samples outside the tolerance range are specifically
marked (“>T” and “<T”) when the single values are printed.
Important: Make sure that the plausibility limit is greater than the defined tolerances:
Weight values that are within the tolerance range but exceed the plausibility limit cannot
be transferred to the statistics. If necessary, change the limit value for plausible weight
values (section 6.3.7).
As soon as the nominal value and tolerances have been entered, a graphic weighing-in
aid (“SmartTrac”) appears in the display with tolerance markers, which simplify weighing
in to the nominal value. You can roughly weigh in your samples until the lower tolerance
value is reached and then accurately dose, if necessary, up to the nominal value.
