Configuring Weighing Platforms
Analog/Digital Converter (ADC)
Purpose Adjust the parameters of the analog/digital converter to the connected load cell or
weighing platform. After ADC configuration, the ADC in connection with the load
sensor is defined as a scale.
Once the ADC configuration has been locked, the indicator can no longer be used
3
to influence weighing results. The scope of functions available in the weighing
instrument is defined by the A/D converter. Weighing functions that can be
activated include reading weight values, taring, adjustment, reading the tare
value and saving/deleting the tare entry.
Setup information – ADC configuration is only possible when the menu access switch is open. Close
the menu access switch after ADC configuration, as otherwise there will not be
any display of the conditions “overload" ( H ) and “underload" ( L ).
– Before ADC configuration, you must first set whether or not the weighing
platform will be used as a standard or verifiable weighing platform under menu
item 9.1.
– When the Service mode is activated, the ADC configuration takes place in the
Setup menu under WP-1 for the first weighing platform and under COm1 /
WP-2 for the second weighing platform.
If you return to the highest level of the Setup menu without saving the
3
configuration parameters beforehand (menu item 11.10) any settings that have
been made will be deleted.
– The settings are made in the corresponding Setup menu under menu item 11.
– Enter the maximum capacities in a suitable weight unit, without any decimal
places (decimal places will be truncated by the rounding function).
– Entries made in the ADC configuration will not be affected by a menu reset
(returning the setup parameters to their factory settings).

Configuring Weighing Platforms
Setting Parameters for ADC Configuration
Standard or verifiable configuration In ADC configuration, you must first select whether the weighing platform should
be configured as a standard or verifiable (for use in legal metrology) weighing
platform.
– Standard configuration STANDRD (9.1.3)
– Verifiable configuration VERIF. (9.1.4)
Configuration unit 1.WT.UNIT Menu item 1.7
The weight unit used in the ADC configuration must have previously been selected
here.
Range selection RANGE Menu item 11.3
Depending on the setting under this menu item, the Menu items 11.5, 11.6 and
11.7 will either be displayed or will not be displayed for further configurations.
– Single-range scale (11.3.1)
The entire weighing capacity is divided into decimal numbers dependent on the
smallest scale interval d and the maximum weight. The readability corresponds
to the scale interval d.
– Multiple-range scale (11.3.2)
A multiple-range scale has two or three weighing ranges. When the range limit
for the lower weighing range is exceeded, the scale switches into the next
highest weighing range (lower resolution). The scale only switches back to the
lower weighing range (higher resolution) when the weighing platform has been
completely unloaded after pressing the key (.
– Multi-interval scale (11.3.3)
The function “Multi-interval scale" divides the weighing capacity into a
maximum of three ranges with differing readability. The corresponding change
takes place automatically at the defined range limits. Once the scale has been
tared, the highest possible resolution is available even if the weighing platform
is loaded.
Scale interval d Scale interval d indicates the resolution of the weighing instrument.
The scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc.
When “Verifiable configuration” is used, this menu item is not displayed. When
using verifiable or verified weighing platforms (classes l and m), scale interval d is
the same as verification scale interval e.
Verification scale interval e Verification scale interval e indicates the resolution of the weighing instrument in
legal metrology.
The scale interval can only be entered in increments of 1, 2, 5, 10, 20, etc.
When “Standard configuration" is used, this menu item is not displayed.
Maximum load (max. load) The maximum load is the maximum amount of weight that may be placed on the
weighing platform. When heavier weights are used the weighing instrument
displays overload “H".
The scale intervals of the weighing instrument are calculated using the maximum
load and the scale interval d (e.g. max. capacity = 15.000 kg, smallest scale interval
d = 0.005 kg yields 3000 scale intervals).
In legal metrology the total number of intervals must be no more than 3000 e, and
when using multi-interval scales there must not be more than 3000 e intervals per
range.
In standard operation, as opposed to legal metrology, you can define a “Super
Range” weighing instrument of over 3000 intervals. These parameters, however,
may be influenced by physical restrictions.

Minimum load (min. load) When “Standard configuration” is used, this menu item is not displayed.
The minimum load of the connected weighing platform is entered under this menu
item. The minimum load for scales of class l is 20 e and 10 e for class m.
Attention: The function of the minimum load setting is to warn operators that
below this limit, the summation of tolerances might lead to significant measurement errors. In Germany, for example, initial weights below the minimum load are
not allowed.
