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.
