Sartorius Signum 3 Operating Instruction

Storage Parameter
The reference weight is saved when
the scale 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.
In the operating menu, under:
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
“At increased stability,” the reference
weight saved will be more accurate
and the results more reproducible,
but the response time of the weighing
instrument might be longer.
Accuracy Level for Calculation
of Reference Value
The resolution applied for calculating
the reference weight is defined in the
operating menu under:
appl1:
Neutr.M: 3.9.
The resolution for calculating the
reference sample weight is increased
if “+1 decimal place”, “+2 decimal
places” or “With internal resolution”
is selected. With the “+1 decimal place”
setting, the net value is determined
to one additional decimal place
(i.e., display accuracy +10); “+2 decimal
places” increases display accuracy
+100, and so on up to the maximum
resolution available.
Decimal Places for Display of Results
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 the operating menu
under:
appl1:
Neutr.M: 3.10.
Minimum Load
The minimum load required for
initialization of the weighing platform
is configured in the operating menu,
under:
appl1:
Neutr.M: 3.6.
Once the limit is exceeded by the load,
initialization can begin. If the load is
too light, the following will occur when
you try to save a value:
– The error code
Inf 29 is displayed
– An acoustic signal (double beep) is
emitted
– The scale is not initialized
– The preset calculation factor is saved
The minimum load required for auto-
matic taring of the container weight
on the platform (“autotare first weight”)
is configured in the operating menu
under:
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 weighing 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
equivalent weighing platforms
– Neutral measurement with one
reference weighing instrument and
one measurement platform
Neutral Measurement with two
equivalent weighing platforms:
Use this mode when samples of widely
varying weight are measured at one
workstation. For example, measure the
lighter-weight samples on one platform
and the heavier samples on another.
You can define which of the two
platforms is active when the Signum
is switched on. This is configured in
the operating menu, under:
setup:
utilit:
8.11. : (main scale)
The main scale 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 weighing instrument and
one measurement platform:
In this mode, a high-resolution
weighing instrument with a relatively
low maximum capacity is used as
a reference weighing instrument. The
measuring platform has a high capacity,
but a relatively low resolution.
This allows you to both determine the
reference value 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
instrument for initialization. Following
initialization, the platform for larger
amounts is automatically activated.
The definition of one weighing
instrument as a reference instrument
is configured in the operating menu,
under:
appl1:
Neutr.M: 3.13.
