Sartorius Signum 3 Operating Instruction

Reference Sample Updating
In the operating menu, under:
appl1: count: 3.12.
you can define whether or not the
reference sample weight is automatically
updated during weighing. Reference
sample updating is performed auto-
matically only when the following
6 criteria are met:
1. The APW Update item in the operating
menu is set to
3.12.3 (“Automatic”).
2. The current piece count exceeds the
original piece count by at least two
3. The current piece count is less than
twice the original piece count (does
not apply for the first updating opera-
tion if the piece count is entered using
the keypad or a bar code scanner)
4. The new piece count is less than 1000
5. The internally calculated piece count
(e.g., 17.24 pcs) differs by less than
± 0.3 pcs from the nearest whole
number (in this example: 17).
6. The scale is stable in accordance with
the defined stability parameter.
If automatic reference sample updating
is selected in the operating menu
and the piece count (pcs) is displayed,
the
Auto symbol is displayed below
the bar graph. If the reference sample
weight has been updated since you
began weighing, the text line shows
the “optimized” code: (
opt.). During
an updating operation,
0pt and the
updated piece count are displayed
briefly in the measured value line.
The new reference sample weight and
reference sample quantity are saved.

Counting with Two Weighing
Platforms
You can use two weighing instruments
simultaneously with the Counting
application. When using two platforms,
you can choose from the following
operating modes:
– Counting with two equivalent weighing
platforms
– Counting with one reference weighing
instrument and one counting platform
Counting with two equivalent
weighing platforms:
Use this mode when samples of widely
varying weight are counted at one
workstation. For example, count the
lighter-weight pieces on one platform
and the heavier pieces 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 Counting application.
Counting with one reference weighing
instrument and one counting platform:
In this mode, a high-resolution weigh-
ing instrument with a relatively low
maximum capacity is used as a refer-
ence weighing instrument. The count-
ing platform has a high capacity,
but a relatively low resolution.
This allows you to both determine
the reference sample weight with high
resolution; i.e., very precisely, and to
count large amounts of parts, without
requiring an expensive high-resolution,
high-capacity weighing platform.
The system can be configured to switch
automatically to the reference instru-
ment for initialization (the measured
value line shows
Ref). Following
initialization, you can switch to the
counting platform.
The definition of one weighing
instrument as the reference instrument
is configured in the operating menu,
under:
appl1: count: 3.13.
If automatic reference sample updating
is enabled, the update is performed
on the active platform; in other words,
the system does not automatically
switch to the reference instrument.
