Neutral Measurement Z nm
When the Neutral Measurement
application is selected, you can use your
weighing platform to measure
the length, surface and volume of parts
that have roughly the same specific
weight. The o symbol is displayed as the
weight unit .
Features:
– Store reference weight from the value
on the weighing platform
– Enter the reference weight using a bar
code scanner
– Enter the tare weight using a bar code
scanner
– Toggle the display between measured
value and weight by pressing w.
– Info mode
Factory settings:
– Minimum load for automatic taring and
automatic printing: 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)
– Decimal places displayed: None (3.10.1)
– Storage parameter: At stability (3.11.1)
– Reference platform: Off (3.13.1)
– Reference value: 1

Operating the Combics 2
In order to calculate the length, surface
or volume of a given sample, the
average weight of a reference quantity
of the sample material must be known
(in the example below, the reference
is 1 meter of electrical cable). There are
2 ways to enter this reference weight in
the Combics weighing platform:
– 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 unit value is shown in
the numeric display.
How the reference weight is calculated
depends on the Application setting for
resolution (3.9). It is either rounded
off in accordance with the display
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 weight; then con-
tinue as described above.
– By entering the reference weight (i.e.,
the weight of 1 unit) using a bar code
scanner. In this case, the value is stored
automatically without pressing O.
The value for the reference weight
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
reference weight stored will be more
accurate and the results more
reproducible, but the response time of
the weighing platform might be longer.
