Parameter for saving weight values
The reference weight is saved when the
scale has stabilized.
“Stability” is defined as the point at
which the fluctuation of a measured
value lies within a defined tolerance
range. The narrower the tolerance
range, the more stable the platform
is at “stability”.
In Setup, under:
Appl
: Z nM: 3.11.
Signum
®
3:
appl1
:
Neutr.M:3.11.
You can define whether the value is
saved when “standard stability” is
reached, or only at “increased stability”
(narrower tolerance range). If you
select “increased stability” the reference
weight saved will be more accurate and
the results more reproducible, but the
response time of the weighing platform
might be longer.
Accuracy Level for Calculation of
Reference Value
The resolution applied for calculating
the reference weight is defined in
Setup under:
Appl
: Z nM: 3.9.
Signum
®
3:
appl1
:
Neutr.M: 3.9.
The resolution for calculating the
reference weight is increased if
“+1 decimal place,” “+2 decimal
places” or “Internal resolution” is
selected. With the “+1 decimal place”
setting, the net value is determined
to one additional decimal place (i.e.,
display accuracy x 10); “+2 decimal
places” increases display accuracy x
100, and “Internal resolution” uses
the maximum resolution available.
Decimal Places in Displayed Result
In neutral measurement, not only whole
numbers but also decimal numbers
(for example, 1.25 o electrical cabling)
can be displayed. The number of
decimal places displayed in neutral
measurement is configured in Setup
under:
Appl
: Z nM: 3.10.
Signum
®

:
Neutr.M: 3.10.
Minimum load
The minimum load required for
initialization of the weighing platform
is configured in Setup under:
Appl: Z nM: 3.6.
Signum
®
3:
appl1
:
Neutr.M: 3.6.
Once the limit is exceeded by the load,
initialization can begin.
If the load on platform is too light,
the following will occur when you try
to save a value:
– The error code Inf 29 is displayed
– A warning signal is emitted (double-
beep)
– The weighing platform is not initialized
– The preset calculation factor is saved
The minimum load required for
automatic taring of the container
weight on the platform (first weight)
is configured in Setup under:
Appl
: Z nM: 3.5.
Signum
®
3:
appl
: m.weigh: 3.5.
You can choose from the following
10 levels for this setting:
1 digit
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
=1000 digits) on the weighing platform
for initialization.
Neutral Measurement with
Two Weighing Platforms
You can use two weighing platforms
simultaneously with the Neutral
Measurement application. When using
two platforms, you can choose from
the following operating modes:
– Neutral measurement with two
weighing platforms
– Neutral measurement with one
reference platform and one weighing
platform
Neutral measurement with two
platforms of the same type:
Use this operating mode to measure
different types of sample material with
different weights. For example, measure
the lighter-weight samples on one
platform and the heavier samples on
another.
You can define one of the two
platforms as the default scale.
This is configured in Setup, under:
setup:
utilit:
8.11. : (main scale)
This is the first platform active when
you switch on the Signum, regardless of
the setting for automatic initialization
of the Neutral Measurement
application.
Neutral Measurement with One
Reference Platform and One Weighing
Platform:
In this operating mode, the reference
platform is a high-resolution weighing
platform with a relatively low maximum
capacity. The other platform is used
for weighing heavier samples, and has
a high capacity with a relatively low
resolution.
This allows you to both determine the
reference weight with high resolution;
i.e., very precisely, and to measure large
samples, without requiring an expensive
high-resolution, high-capacity weighing
platform.
The system can be configured to
switch automatically to the reference
platform for initialization. Following
initialization, the platform for larger
amounts is automatically activated.
The definition of one weighing platform
as a reference platform is configured in
Setup, under:
Appl
: Z nM: 3.13.

:
Neutr.M: 3.13.
