Configuring the
Analog/Digital Converter
Purpose
Configure the analog/digital
converter by selecting the required
parameters in the Setup menu to
adapt your FCT01 terminal for use
with all commercially available
strain-gauge load cells, as well as
with Sartorius IWA, IU or IF analog
weighing platforms. Access to
settings for A/D converter
configuration is password-protected.
Features
With the menu access switch open,
you can configure the following
parameters:
– Weighing mode: “standard” or
“trade” (scale verified for use in
trade/in legal metrology)
– Verifcation scale interval e
– Scale interval d
– Minimum capacity
– Maximum capacity
– Maximum capacity for each
weighing range
– Verification scale interval e for
each weighing range
– Accessibility of weight units
These parameters are not reset when
you restore factory settings.
Depending on the weighing mode
selected, the configuration options for
parameters not listed above are the
same as they are in a corresponding
Sartorius weighing instrument that
cannot be switched between
“standard” and “trade” modes.
Note on Settings
Configure the maximum capacity for
each weighing range in a suitable
weight unit, without values other than
“0” in decimal places. Select the
desired weight unit under the “Lock
units” menu item. For purposes of
display in the metrology line, the
maximum capacity for all ranges must
be configured so that they can be
displayed with a maximum of 4 digits
other than “0” for all available weight
units. The same applies for releasing
and locking weight units 1 and 2.
The unit selected for configuration
cannot be excluded.
Testing and Configuration
for Use in Legal Metrology
The metrological data is displayed
for approximately 2 seconds for each
range in sequence in the metrology
line when you switch on the weighing
instrument. After configuration,
calibration and adjustment, return the
menu access switch to the “closed”
position.
Unter Setup: Balance/Scale
functions: Weight unit 1, you can
check to make sure that only the
permissible weight units are
accessible.
Description of the Individual Menu
Items
Standard Scale
Standard or
Verified/Verifiable Scale (Legal for
Trade)
Trade
When you configure the weighing
instrument, you must define whether
or not it is to be used for legal
metrology.
Class
For a verified or verifiable weighing
instrument, you need to select the
accuracy class. Which class you
should select depends on the
weighing platform. The only settings
permitted in legal metrology are
Classes K, l and m.
Ranges
The weighing range can be divided
into multiple ranges, if desired.
Single-range Weighing
Instrument
The entire weighing range is divided
into scale intervals which are
dependent on the lowest scale
interval d and the maximum capacity.
Readability for the entire weighing
range is always the lowest scale
interval d.
Multi-interval Weighing
Instrument
These weighing ranges can have
different levels of accuracy. The multi-
interval function divides the weighing
range into as many as 4 ranges,
each with a different readability. This
means that the weight readout is
displayed with the accuracy of the
particular weight range. The
readability automatically adjusts each
time the weight on the load receptor
exceeds the defined limit of a range
subdivision. When a weight causes
the weighing instrument to change
from a higher to a lower range, the
higher resolution is automatically
selected. After taring, the highest
possible resolution of the first range is
restored, even when the weighing
platform is loaded.
