the sliders for filling (9) are opened.
5. Fill the container with the selected wall
anchor type.
6. Continue to fill the container with the
selected dowel type.
7. The weight reached is compared with the
setpoint specifications as soon as the scale
comes to a standstill.
The quality is positive (true), when

Outside of these limits, the quality is
assessed as negative (false). The
determined values are saved as new entry

8. Finally the assessed packet is removed.
Remove the packet from the scale and

The filling process is indicated by
the flashing blue arrow.
The setpoint weight deviation is
displayed on the packet.
As of 90% of the setpoint weight
(>-10% of the weight deviation)
the 2nd slider is closed and
reduces the filling speed.
The slow filling speed is indicated
by the flashing white arrow.
From 100% of the setpoint weight
(>=0% of the weight deviation)
the 1st slider is also closed and
filling is finished.
