5.4.8 DR 4 - Type: Discontinuous totalizing
Automatic Totalising Filling Instrument – conforming with OIML R-107 – Automatic
Weighing Instrument (AWI). The scale doses out the entire amount in individual
portions. Emptying the scale is part of the automatic operating cycle and is
important for determining amounts.
The start of the weighing procedure sets the scale to zero. The scale container is
then filled. After filling, the scale waits for stand-still 3, switches to sampling
operation and tares. After emptying and achieving stand-still 2, the achieved net
weight is totalised.
The weighing procedure is clarified by the following image

5.4.9 DR 4 – Type: filling (additive)/(Big-bag)
Automatic Gravimetric Filling Instrument – conforming to OIML R-61 - Automatic
Weighing Instrument (AWI) type. As an automatic weighing instrument of type
gravimetric filling, the scale doses single quantities in continuous operation until the
defined setpoint (fill weight of the big bag) is reached. Emptying the scale is part of
the automatic operation cycle.
The start of the weighing procedure sets the scale to zero. The weighing container
is then filled. Net weight totalizing occurs when the set weight of the catch weighing
