Configuring The Analog/Digital Converter - Sartorius combics 1 Operating Instructions Manual

Service
Configuring the Analog/
Digital Converter (ADC)
Purpose
Adapt the parameters of the analog/
digital converter to the connected load
cell or weighing instrument. Once
these parameters have been configured,
the A/D converter in conjunction with
the load cell(s) is defined as a weighing
instrument.
Note on Settings
– The A/D converter can be configured
only in the service mode and only with
the menu access switch open. Make
sure you close the menu access switch
following A/D converter configuration;
otherwise, the "overload" (H) and
"underload" (L) error codes are not
shown.
Diagram of the Menu for A/D Converter Configuration
The following menu items are appended to the numeric menus for WP1 (WP-1) and WP2 (WP-2)
in the service mode for configuring the A/D converter:
9.1 Restore Factory Settings / Reset the Menu
9.1.3 Standard Configuration
78
– Configure the A/D converter in the
Setup menu (in service mode) for the
first weighing instrument under "WP-1"
and for the second weighing instrument
under "Com1, WP-2" or "UniCOM,
WP-2." Settings are configured in the
corresponding numeric menu under
menu item 11.
– Before configuring the A/D converter,
you must define whether the weighing
instrument is to be used in the "stan-
dard" mode or in the "trade" mode
(verified for use in trade/legal metro-
logy), under menu item 9.1.
– Enter the maximum capacity (max.
cap.) in a suitable weight unit, without
decimal places (the rounding function
will cut off any decimal places).

!
If you return to the highest level of the
numeric menu without saving changes
(menu item 11.10), all changes made
up to that point are lost.
– The menu-reset function ("Restore
Factory Settings") does not affect
settings for A/D converter configu-
ration.
!
Note:
Once the A/D converter configuration
has been locked (menu access switch
closed), 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: read weight
value, tare, calibrate/adjust, read tare
value, save/delete tare input
