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.
3
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.

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

confirm your selection using the “

“ 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.
