7.2 Operation
WIEGEN mit TARIEREN/WEIGHING with TARE
During weighing in a certain weight amount of a product is to be filled into a weighing container with-
out the tare weight of the container being weighed. The weighing container is excluded from consid-
eration by using TARE and thus only the measured value of the product is indicated. The maximum
weighing range is reduced by the value of the tare weighing container – tare is therefore classed as
being subtractive. Wait until the g or kg unit symbol appears on the display. The weighing result is
now stable.
ZÄHLEN-Referenzstück auswählen/COUNT-Selection reference piece
In order to be able to count a larger quantity of parts it is necessary to determine the average weight
of each part using a small quantity (
reference piece number ).
The greater the reference piece number, the greater the counting accuracy.
In the case of small or very varied parts, a particularly high reference piece number must be selected.
ZÄHLEN/COUNT
Commence by applying the number of parts of the determined reference piece number.
Using the automatic reference optimization (
OPT ) the counting accuracy is automatically increased
when applying up to 100 items.
Now apply the quantity to be counted.
PERCENT/ %
When using percentage weighing it is possible to remove partial amounts from the weighing con-
tainer.
Instead of the manual withdrawal there can also, for example, the evaporated amount of moisture
during a drying sequence be displayed as a percentage.
To begin with the percentage of the removed parts is displayed.
The remaining amount in the container is shown as a percentage by operating the REZ key.
REZEPTURWÄGUNG/FORMULA WEIGHING
The formula weighing function makes it possible to weigh in several components ( K1, K2, ...,Kn ) in
succession and subsequently determine the total weight of the components.
Return to weighing mode by pressing the ESC key.
PLUS-MINUS-WÄGUNG/Tolerance weighing
When using tolerance weighing the parts to be checked are compared with a target value and the
divergence displayed as a plus or minus value when compared to the target value.
