Operating instructions

The ranges are divided as desired by
selecting the assigned menu item with
key k and confirm with the ) key.
A circle (o) appears behind the selected
menu item as a marker.
Scale Interval d
The lowest scale interval d indicates the
weighing instrument's resolution. You
can only enter it in the scale intervals
1, 2, 5, 10, 20 etc. If you have selected
the “Trade" setting (accuracy class l)
the lowest scale interval d is not
prompted because it is equal to the
verification scale interval e.
Verification Scale Interval e
When “Standard configuration” is
active, this menu item is not displayed.
The verification scale interval e indicates
the resolution of the weighing instru-
ment in legal metrology. With accuracy
class l, the verification e is
the same as scale interval d. Thus, with
classes l, the lowest scale interval d is
not prompted.
Minimum capacity Min. cap.
When “Standard configuration” is
active, this menu item is not displayed.
The minimum weight for weighing
instruments of accuracy class l is
20 e and for accuracy class, 10 e.
Caution: The minimum capacity limits
have the function of warning the
equipment operator that loads below
these limits lead to cumulative addition
of the tolerances, which can result in
significant errors of measurement. In
Germany, for example, weighing below
the minimum capacity is not permitted.
Range 1, Range 2, Range 3
Enter the limits for the individual
ranges. When a given limit is exceeded,
the accuracy changes.
The following applies for all limits:
Range 1 < Range 2 < Range 3
< Max. cap.
Thus, you can divide the weighing
range into 4 ranges. The display resolu-
tion changes in intervals of 1, 2, 5, 10,
20 etc. The lowest resolution is the
lowest scale interval d. Ranges you do
not require should be set to 0.
Maximum capacity Max. cap.
The maximum capacity is the maximum
load that may be placed on the weigh-
ing instrument. If the weight exceeds
this capacity, the weighing instrument
will display H.
The scale intervals are calculated from
the maximum load and the lowest scale
interval d. In legal for trade applica-
tions, the number of verification scale
divisions may not be greater than
10,000 e. In the “standard" weighing
mode, as opposed to “trade," you can
define a “SuperRange" to increase the
permitted intervals:
For example, a maximum capacity of
50,00 lb combined with a smallest
interval d of 0.01 lb, yields 50,00 scale
intervals. These parameters, however,
may be influenced by physical
limitations.
Lock units (menu item 11-7)
With this function, you can make
particular weighing units inaccessible
during weighing. Accessible units are
marked by a circle (o) on the indicator
(multiple range selection is possible).
Calibration/Adjustment Unit
(Menu item 11-8)
The calibration unit defines the weight
unit with which calibration must be
performed. This unit will be used even
if a different unit has been selected for
the weighing mode.
Store settings
(menu item 11-10)
Save the A/D converter configuration
by selecting menu item 11-10-1.
Once these parameters have been
configured, the A/D converter in
conjunction with the weighing cell is
defined as a weighing instrument. The
A/D converter, in conjunction with the
weighing platform, can now be used
like any standard weighing platform.
In addition, the weight unit must be
defined and the weighing platform
adjusted (calibration/adjustment
and linearization). For more detailed
instructions, see the chapter entitled
“Calibrating in the Service Mode."
Adjustment without Weights
(menu item 1-19)
The parameters for “Nominal capacity"
in kg (menu item 1-19-1) (specification
of the strain-gauge beam), “Resolution"
in kg (menu item 1-19-2) and “Sensitiv-
ity" in mV/V (menu item 1-19-3) are
converted to internal quantities. Once
the A/D converter configuration data
has been stored, these parameters can
no longer be read out. For platforms
with multiple load cells, the sensitivity
of the additional cells is entered by
selecting menu item 1-19-4 (cell 2) to
menu item 1-19-6 (cell 4).
Save the entered data by selecting the
menu item 1-19-7.
! Important Note:
Please do not forget to set the menu
access switch (15) to “locked" when you
have finished configuring the
A/D converter and performing the
adjustment (calibration/adjustment
and linearization).
Weighing results can no longer be
influenced by the Combics after the A/D
converter has been configured.
The range of available weighing instru-
ment functions is defined in the A/D
converter. The following functions, for
example, can be activated:
– Read weighing results
– Tare
– Adjustment
– Read tare value
– Save/delete tare input
