By pressing the key several times, more reference quantities 10, 20, 25 and 50
can be called up.
Place as many pieces to count on the weighing plate as the set reference quantity
requires.
Confirm with key.
The balance is now in parts counting mode counting all units on the weighing plate
By pressing the key the balance returns to the weighing mode and displays the
weight of the counted units.
Important: The larger the reference quantity, the more accurate the parts
counting.

The tare vessels can also be used for piece counting. Prior to the piece count tare
the tare vessel with key.
6.7 Net-total weighings
It is useful if a mixture of several components is weighed into a tare vessel and finally
the sum weight of all weighed components is necessary for control purposes (net-
total, i.e. the weight of the tare vessel).
Example:
Switch-on the balance using the key and wait for the
„0“ display.
Put tare vessel onto weighing plate, tare with key to „0“.
Weigh component  and tare with
key (Memory) to „0“. The memory activation is
indicated by a triangle on the left border of the display.
Weigh component , when pressing the key appears the net-total, that means,
the sum weight of the components  and  . Tare to „0“ using the key.
Weigh component  , when pressing the key, appears the net-total, i.e. the sum
weight of components  and  and .
If necessary, also fill the formula up to the desired final value.
