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 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, saving/deleting the tare entry.
Setup information
– ADC configuration is only possible when the menu access switch is open. Re-close the menu
access switch after ADC configuration.
– Before ADC configuration, you must first set whether or not the weighing platform will be
used as a standard or verifiable weighing platform.
– ADC configuration is carried out in the Service mode in the Setup menu under “
WP 1" for
the first weighing platform and “
WP 2" for the second.
– Entries made in ADC configuration will not be affected by a menu reset (returning the setup
parameters to their factory settings).
See also the overview in the “Setup Menu for A/D Converter Configuration" section.
Setting Parameters for ADC Configuration
Standard or Verifiable Configurations
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 “
Standard"
– Verifiable configuration “
Verifiable"
Select using the “
Q"or “q" soft key. Press the “O" soft key to confirm the setting and open
the Configuration menu.
Accuracy class
This menu item is not shown when the Standard configuration is active. When the Verifiable
configuration is active (for weighing platforms verified or verifiable for use in legal
metrology), only Class l/m can be selected. Activate the “
Accuracy class"
menu item, select “
Class III/IIII" and confirm your selection using the “l"
soft key.
Ranges
The capacity of the weighing platform can be divided into multiple ranges:
–“
Single-range mode":
The entire weighing range is divided into scale intervals on the basis of the lowest interval d
and the maximum load.
–“
Multi-interval mode":
The “Multi-interval mode” function divides the weighing capacity into as many as four
ranges, each with a different readability. Corresponding changes take place automatically.
Once the scale has been tared, the highest possible resolution is available even if the
weighing platform is loaded with a higher weight. This is only permitted in the accuracy
classes l/m for the verifiable configuration.
–“
Multiple-range mode":
Multiple-range mode has two or three weighing ranges. When the range limit is exceeded,
the scale switches into the next highest weighing range (lower resolution) and remains there.
The scale can be returned to the lower weighing range (higher resolution) only by pressing
the ( key and then unloading the scale.
Select the desired configuration using the “
Q" or “q" soft key. Confirm your selection using
the “
O" key. Make additional settings in the submenu: scale interval d/verification scale
interval e, minimum load (Verifiable configuration only), range limits (Multi-interval or
Multiple range mode only) and maximum capacity. Confirm using the “l" soft key or cancel
using “
Esc."
