8.2 Taring
There are two methods of entering a tare value. The first is based on the weight that is on the weighing
platform and the second is based on a value entered by the user.
8.2.1 First method:

Set the scale to zero by pressing the key. An arrow indicator appears above “ Zero ”. Place
a container on the weighing platform. The display will show the value of its weight.

Press the key to tare the scale. The weight that was displayed is stored as the tare value
and this value is subtracted from the display. Zero remains on the display. An arrow indicator
appears above “
Net ”.

When a product is added, only its weight is shown on the display. The scale could be tared a
second time if another type of goods should be added to the first. Again, only the weight added
after taring is displayed.

When the container is removed, a negative value is shown on the display. If the scale was tared
shortly before removing the container, this value is the gross weight of the container plus any
products that were removed. The arrow indicator above “
Zero ” is also on because the weighing
platform is under the same condition as the last time the key was pressed.
8.2.2 Second method:

This method allows you to enter a value for the tare weight using the keypad. This is useful when
you are using the same containers, or when the container is already full while the net weight is
required and the weight of the container is known.

Remove all objects from the weighing platform and press the key to reset the display to
zero. Enter the tare weight value (including the decimal point) using the keypad and press
to save the tare value. The weight has a negative value, identical to the tare value.

Place the container on the weighing platform.

The display shows the weight of the container minus the tare weight.

When the full container is placed on the weighing platform, the tare value is subtracted from the
gross weight. Only the net weight of the content is displayed.

If the input value does not match the digit increment on the scale, the tare value of the scale is
rounded up to the next possible value. For example, if a tare value of 10.35 g is entered for the 6
kg/0.2 g scale, the scale will show -10.4 g.
8.3 Unit counting
8.3.1 Setting the unit weight
In order to perform unit counting, it is necessary to know the average weight of the individual units to be
counted. This can be done by weighing a known number of individual units and determining the average
unit weight from the scale, or by manually entering a known unit weight via the keypad.
