Checkweighing Application O
Application 2: Checkweighing O
Minimum Load
The minimum load required for
automatic taring of the container
weight on the platform (rst weight),
or for automatic printout of results,
iscongured in Setup under:
Appl
: m.weigh: 3.5.
You can choose from the following
10levels for this setting:
1 digit (no minimum load)
2 digits
5 digits
10 digits
20 digits
50 digits
100 digits
200 digits
500 digits
1000 digits
The “digits” here refer to the scale
intervals in the connected weighing
platform� If the interval of the
connected platform is 1 g, for example,
and 1000 digits are required, you must
place at least 1000 g (= 1000 intervals)
on the weighing platform to activate
autotaring or autoprint�
Display
The result of a measurement is shown
either as a weight value or in relation to
the target�
– Weight display
The measured value line always shows
the weight value, even if it lies outside
the tolerance range�
The bar graph is displayed with symbols
indicating lower limit, target and upper
limit� Weights are shown logarithmically
up to the lower tolerance limit, and
linearly beyond that point�
– Relation to target value
As “Weight display” above, with the
exception that:
– LL appears in the main display if the
weight value is less than the lower
limit
– HH is shown on the main display if
the weight value is higher than the
upper tolerance limit
Digital I|O Interface
The Checkweighing application
supports the digital input|output-
interface�
There are 4 control lines, or outputs,
which are activated as follows (see also
the diagram below):
– Lighter
– Equal
– Heavier
– Set
In Setup menu:
Appl 2:
check.wg: 4.4.
you can define whether these control
ports are
– off
– always on
– activated at stability
– on within the checkweighing range
– on at stability within checkweighing
range
The “SET” output normally changes its
voltage level when the load is near the
target weight� Alternatively, you can
assign the “Ready for use” function to
this port� Configured in Setup under:
Appl 2:
check.wg: 4.3.
This enables you to, for example,
connect a simple indicator for weighing
or calculation results�
All data output ports have a high
voltage level when:
– The application has not been initialized
– The weighing instrument is not at
stability and one of the “at stability ���”
parameters is selected
– The weight is not within checkweighing
range
Digital I|O Interface
– “SET” control output: set
– port lines: always on
Digital I|O Interface
– “SET” control output: set
– port lines: within the checkweighing
range
Output port specifications:
– When not in use, the voltage level is
high: >3�7 V/+4 mA
– When activated, the voltage level is low:
<0�4 V/–4 mA
! The data outputs are not protected
from short circuits�
