To select the weighing unit press the
[Unit] key to move form one unit to
another. The weighing unit must be enabled by the users beforehand
(see section 13.1.3). If a unit is disabled it cannot be selected by using
the
[Unit] key.

• When the scale is at zero, place an item to be weighed on
the platform. The display will show the weight in the unit
selected previously. The weighing result can be viewed in
other enabled units using the
[Unit] key.

The scale then shows the net weight of the material added.
