Weighing In Percent - Sartorius Signum 1 Operating Instruction

Application 1: Weighing in Percent L
With the Weighing in Percent applica-
tion, you can have the value of the
weight on the platform displayed as
a percentage calculated in relation
to a defined reference weight.
The L symbol is displayed in place
of the weight unit.
Features
Signum 3 only:
– Enter the reference weight "Wxx%" for
100% via the keypad
– Save the current weight value as
reference percentage ("pRef")
Signum 3 only:
– Enter the reference percentage
"pRef" via the keypad
– Enter reference sample weight using
a bar code scanner
– Display result as loss (difference) or
residue
– Display up to 3 decimal places.
Configure in the operating menu,
under:
appl1 :
Perc.wg : 3.10.
– Weigh in percent with two weighing
platforms
– Activate info-mode by pressing I
– Toggle the display between percentage
and weight by pressing the w key.
– Automatic taring of container weight.
Operating menu setting:
Appl : a.tare : 3.7.
– Automatic initialization when the
Signum is switched on. The application
is initialized with the most recently
saved data. Operating menu setting:
Appl : a.start : 3.8.
– Closing application program;
deleting parameters:
The value for reference sample weight
remains active in the reference memory
until you delete it by pressing the c
key, overwrite it or until you select a
different application. It also remains
saved after the scale has been switched
off.
Signum 3 only:
You can select the function of the
c key for clearing application data.
When an application is active, this key
can either delete the values saved for
all applications, or delete selected
values saved for the active application.
Operating menu setting:
Appl : sel.cf : 3.24.
(select CF key function in applications)
– Tare function:
1) If you store a tare (weight value) by
pressing the ) key, you can later
enter a tare value manually. The tare
value you enter is added to the stored
tare value.
Setting: menu code 3.25.1 (factory
default)
2) A tare value entered manually over-
writes a stored tare value (weight
value). If you enter a tare value manu-
ally, a tare value (weight value) stored
later overwrites the manually entered
value.
Setting: menu code 3.25.2
Operating menu setting:
Signum 2
Appl : L : 3.25.
Signum 3
Appl : tare. f : 3.25.
– Restore factory default settings. Operat-
ing menu setting:
Signum 2:
Appl : L : 9.1.
Signum 3:
Appl : DEF.App : 9.1.
To determine the weight of a sample
relative to a reference weight, you need
to define the reference weight value.
There are three ways to enter this value
in the application program:
– Calculation:
– Place the reference quantity
(defined by the reference percent-
age) on the connected weighing
platform and press O.
– Place any amount of the sample
material on the connected weighing
platform, enter the reference
percentage through the keypad,
and press the r key to initialize
the application.
How the reference weight is calculated
depends on the application setting that
defines "Accuracy for saving weights."
The value is either rounded off in
accordance with the display resolution,
or saved with 10-fold or 100-fold
increased resolution, or with the
maximum internal resolution of the
weighing platform.
– Enter the reference weight for 100%
via the keypad and press the O key
to initialize the application.
– Bar code: If the value is available in
bar code, you can use a bar code
scanner to enter the reference weight
The initial application values are valid
until deleted by pressing the c key
or until overwritten by new values.
They also remain saved after you
switch off the Signum.
