Zero display and the indicator [] next to
T AR E
appear. The weight of the
container is now internally saved.
 Weigh the material, the net weight will be indicated.
 After removing the weighing container, the weight of the weighing container
appears as negative display.
 The tare procedure can be repeated as many times as necessary, for example
with initial weighing of several components for a mix (add-on weighing). The limit
is reached when the total weighing range capacity is full.
 To delete the tare value, remove load from weighing plate and press .
7.6 Counting
During piece counting parts can either be counted into a container or out of a
container. To count a greater number of parts the average weight per part has to be
determined with a small quantity (reference quantity). The larger the reference
quantity, the higher the counting exactness.
High reference must be selected for small parts or parts with considerably different
sizes.
 The average piece weight can only be determined by stable weighing
values.
 If weighing values are under zero, the piece counter display shows a
negative number of items.
 The message light appearing on the display indicates that load falls below
minimum weight value.
 Delete incorrect entries by pressing .
 The accuracy of an average item weight can be improved at any time
during additional counting processes. For this purpose add additional
items and press . After the reference optimization sounds a signal
tone. As the additional pieces increase the base for the calculation, the
reference also becomes more exact.
