Sartorius combics 1 Operating Instructions Manual page 27

Storage Parameter
The reference weight is saved when
the weighing instrument 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 weighing instrument
is at "stability." This setting is also
applied when you zero the weighing
instrument.
Under menu item 3.11 you can
determine whether the value is saved
"At stability" (normal tolerance range)
or "At increased stability" (narrower
tolerance range).
If you select "At increased stability,"
the average piece weight stored will be
more accurate and the results more
reproducible, but the response time of
the weighing instrument might be
longer.
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 under menu item 3.10.
The measured result can be displayed
with 0, 1, 2 or 3 decimal places.
Minimum Load for Initialization
The minimum load for initialization
is configured under menu item 3.6.
If the load exceeds this limit, the
weighing instrument can be initialized.
If the load 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 instrument is not
initialized
– The preset reference value is stored
Neutral Measurement with
Two Weighing Instruments
You can use two weighing instruments
simultaneously with the Neutral Measure-
ment application. When using two
instruments, you can choose from the
following operating modes:
– Neutral measurement with two
equivalent weighing instruments
– Neutral measurement with one
reference weighing instrument and
one measurement platform
Neutral Measurement with Two Equiva-
lent Weighing Instruments
Use this mode when samples of widely
varying weight are measured at one
workstation. Measure the lighter-
weight pieces on one weighing instru-
ment and the heavier pieces on another.
When you press n to toggle from one
weighing instrument to the other, the
application is re-initialized.
You can define which of the two
weighing instruments is active in the
display when the Combics is switched
on (menu item 8.11). This is the first
weighing instrument active when you
switch on the Combics, regardless of
the setting for automatic initialization of
the Neutral Measurement application.
Neutral Measurement with One
Reference Weighing Instrument and
One Measuring 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.
Specify which weighing instrument is the
reference instrument under menu item
3.13. The system toggles automatically
to the reference instrument for initiali-
zation (Ref is shown in the main dis-
play). Following initialization, the system
toggles to the measuring platform.
