Counting Z
When the Counting application is
selected, you can determine the number
of parts that each have approximately
equal weight.
Features:
– Store reference weight from the load
on the weighing platform
– Enter reference weight using a bar
code scanner
– Enter tare weight using a bar code
scanner
– Automatic reference sample updating
(user-definable)
– Counting with 2 weighing platforms
– Toggle the display between piece count
and weight by pressing w
– Info mode
Factory settings:
– Minimum load for automatic taring and
automatic printout: 10 digits (3.5.4)
– Minimum load for automatic initializa-
tion: 1 digit (3.6.1)
– Automatic taring (first weight on
platform tared): Off (3.7.1)
– Application started automatically with
most recent initialization data when
Combics switched on: Off (manual start)
(3.8.2)
– Resolution for reference weight
calculation: Display resolution (3.9.1)
– Storage parameter: At stability (3.11.1)
– Reference sample updating: Automatic
(3.12.3)
– Reference platform: Off (3.13.1)
– Reference sample quantity: 10
Before the quantity on the platform can
be calculated, the average piece weight
must be entered in the application.
There are 2 ways to do this with the
Combics:
– By placing the number of parts defined
as the reference sample quantity on the
weighing platform and pressing O to
calculate and store the average piece
weight.
The reference sample quantity is shown
in the numeric display.
How the reference weight is calculated
depends on the resolution specified in
the Application settings (3.9). It is either
rounded off in accordance with the dis-
play resolution, or stored with 10-fold
or 100-fold resolution, or
with the maximum internal resolution
of the weighing platform. Press the
r key to change the reference sample
quantity; then continue as described
above.
– By entering the reference piece weight
(i.e., the weight of one piece) using
a bar code scanner. In this case, the
value is stored automatically without
pressing O.
The value for the reference sample
quantity remains active in the reference
memory until you overwrite it or until
you select a different application. It also
remains stored after you switch off the
Combics.
Storage Parameter
The reference weight is stored when
the platform has stabilized. “Stability" is
defined as the point at which
fluctuation of a measured value lies
within a defined tolerance range. The
narrower the tolerance range, the more
stable the platform is at “stability".
This setting is also applied when you
zero the weighing platform.
You can set the parameter for “Stability
at initialization" to “At stability"
(normal tolerance range) or “At higher
stability" (limited tolerance range).
If you select “higher stability", the
average piece weight stored will be
more accurate and the results more
reproducible, but the response time
of the weighing platform might be
longer.
