Neutral Measurement D
With this application 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
– Enter the reference weight “wRef”
through the keypad
– Save the reference weight “wRef” from
the weighing platform
– Enter the factor for calculation “nRef”
using the keypad
– Enter reference weight using a bar code
scanner
– Measuring with two weighing platforms
– Activate info-mode by pressing D
(> 2 sec)
– Toggle the display from neutral
measurement to weight by pressing the
Weigh. soft key, and back by press-
ing
Measure.
– Define the level of accuracy (display
resolution) applied when a calculated
reference weight is saved
– Automatic initialization when the
Combics is switched on. The indicator
is initialized with the most recently
used calculation factor “nRef” and
reference weight “wRef”. Configured

In order to calculate the length, surface
or volume of a given sample, the aver-
age weight of a reference quantity of
the sample must be known (in the
example below, the reference is 1 meter
of electrical cable). There are three
ways to enter the reference weight in
the program:
– Calculation:
– Place the reference quantity (defined
by the calculation factor) on the
connected weighing platform and
calculate the reference weight by
pressing the
Start or n= soft
key.
– Place any amount of the sample
material on the connected weighing
platform, enter the calculation factor
through the keypad, and press the
nRef soft key to calculate the
reference weight.
How the reference weight is calculated
depends on the application setting for
resolution. The value is either rounded
off in accordance with the display
resolution, or saved with 10-fold or
100-fold resolution, or with the maxi-
mum internal resolution of the weigh-
ing platform.
– Keypad input: Enter the reference
weight (i.e., the weight of one meter
of electrical cable) using the keypad and
press
wRef to save it.
– By using a bar code scanner
The initial application values are valid
until deleted by pressing the c key
or until overwritten by a new value.
They also remain saved after you turn
off the Combics.
