Minimum Load for Initialization and
Defining the Class 1 Lower Limit
The minimum load defines the
lower limit for Class 1 (i.e., the delimiter
between Classes 0 and 1). The appli-
cation can only be initialized (to define
the upper limit of Class 1) when
the load on the weighing instrument
exceeds the minimum load.
Display
The result of a given measurement
is shown as either a weight value
or the class number. You can toggle
between these two display modes
by pressing w.
– Weight display; 3 classes:
The current weight is shown in the
display; for example: 108.7 g
Class 1 Bar graph:
Numeric display: 1
LED: red is lit
Class 2 Bar graph:
Numeric display: 2
LED: green is lit
Class 3 Bar graph:
Numeric display: 3
LED: yellow is lit
– Weight display; 5 classes
The current weight is shown in the
display; for example: 108.7 g
Class 1 Bar graph:
Numeric display: 1
LED: red is lit
Class 2 Bar graph:
Numeric display: 2
LED: red and green are lit
Class 3 Bar graph:
Numeric display: 3
LED: green is lit
Class 4 Bar graph:
Numeric display: 4
LED: green and yellow are lit
Class 5 Bar graph:
Numeric display: 5
LED: yellow is lit
– Class display; 3 classes
The current class is shown in the
display; for example: class 1 and the
bar graph indicates the current weight.
The LEDs are lit as for the weight
display described above.
– Class display; 5 classes
The current class is shown in the
display; for example: class 1, and the
bar graph indicates the current weight.
The LEDs are lit as for the weight
display described above.
Digital Input/Output Interface
The Classification application supports
the digital input/output-interface.
There are 4 control lines, or outputs,
which are activated as follows (also refer
to the diagram):
– Lighter
– Equal
– Heavier
– Set
The "Set" line usually indicates that the
minimum load is exceeded. Alternatively,
you can assign the "Ready-for-use"
function to this port.
Under menu item 4.7, you can define
whether these control ports are
– inactive (4.7.1),
– always active (4.7.2), or
– active at stability (4.7.3).
This makes it possible, for example,
to connect a simple indicator for
weighing or calculation results, similar
to the 3-segment checkweighing
display on the Combics, or control
an automatic process.
