Service Menu
When the Service mode is activated, the
service technician can access additional
menu items that are not visible when
the Service mode is deactivated.
The following advanced functions are
available:
In the highest menu level, the last item
is now:
–
Factory settings: all
parameters
In the Device parameters
menu, the following items are added to
the menu, below
Code:
–
Service (service date)
–
Memory number (for a
connected Alibi memory)
–
Terminal data (serial number
and model of the indicator)
The first item of the Device Parameters
menu for “WP1 - Internal” is now:
–
ADC configuration.
The
Calibration/
adjustment menu in the Device
Parameters menu for “WP1 - Internal”
now contains the following additional
submenus:
–
Adjust without weights
– Geographical data.
The
CAL key function and
Activate ext. adj. sub-
menus of the “Calibration/Adjustment”
menu also contain additional menu
items.
If the COM1 or COM2 interface is
configured for a second weighing
platform, “WP2”, the additions to the
“Calibration/Adjustment” menu listed
above for “WP1” apply to the “WP2”
menu as well. Under certain conditions,
the “ADC Configuration” menu is also
available for WP2 (if a weighing
platform suitable for this purpose is
connected and a suitable transfer
protocol is used).
In general, the software detects the
parameters of the connected load cell(s).
If the parameters of a given load cell
cannot be detected or cannot be
changed, the parameters in question
might not be displayed. For example,
in the “Calibration/Adjustment” menu,
the “External calibration” item is not
displayed if the connected weighing
cell is not configured for use in legal
metrology; in other words, if it does not
have a “Legal metrology” data record.
A diagram of the menu tree for the
Setup menu in Service mode is shown
on the following pages. As mentioned
above, which menu items are shown
depends on the weighing platform(s)
connected.
Note:
To configure the A/D converter and to
enter or change parameters in the
“Calibration/Adjustment” menu, set the
menu access switch to the “Accessible”
position. To do this, move the switch to
the right (towards the interface
connectors). For details, see
“Configuring the Analog/Digital
Converter” and “Calibration,
Adjustment and Linearization” in this
chapter, as well as the section entitled
“Calibration and Adjustment” under
“Operating the Combics.”
Configuring the
Analog/Digital Converter
Purpose
To adapt the Combics for use with
any commercially available strain-gauge
load cell or analog Sartorius CAPP,
CAPS, IU or IF weighing platform by
selecting or entering parameters in the
Setup program. Access is restricted by
a special password (service password).
Features
With the menu access switch open, you
can configure most of the parameters
affecting the following specifications:
– Toggle between “Standard” and
“Verifiable” (“Legal for trade”) mode
(configuration for use in legal
metrology)
– Verification scale interval e
– Scale interval d
– Minimum load
– Maximum load
– Maximum load for a given range
– Verification scale interval e for a given
range
– Available weight units
– Weight unit for calibration/adjustment
These parameters are not affected when
you restore the factory settings (menu
item:
Factory settings:
all parameters on the
highest level of the Setup menu.
Parameters not listed above are not
affected by your choice of Standard
or Trade configuration; the same
restrictions apply as for Sartorius
weighing instruments that do not
offer a choice between the two
configurations.
Note on Settings
The
ADC configuration
menu is opened from the Setup menu,
under
Device parameters
(weighing platform 1: WP1; weighing
platform 2:
COM1 or COM2, with
suitable transfer protocol).
The menu is shown on page 66.
For details on opening the Setup menu,
see “Configuring the Combics”.
The A/D converter can be configured
only in the Service mode and only with
the menu access switch open.
