The A/D converter can now be treated like a standard weighing platform in
connection with the load sensor.
t Close the menu access switch (right position) and reattach the cap.

Once ADC configuration has been completed, an adjustment of the weighing
platform (calibration/adjustment and linearization) must be carried out (see page 47
and “Calibration/Adjustment without Weights", page 30).
Entering Geographical Data for Use in Legal Metrology
Purpose Entering geographical data allows the external adjustment of weighing equipment
at a place (e.g. at the manufacturer or vendor's place of business) that is not the
same as the place of installation. If the weighing equipment is adjusted at the place
of installation, it is not necessary to enter geographical data.
The sensitivity of weighing equipment changes depending on the place of
installation as it is dependent on the on-site gravitational force – or, more precisely,
on gravitational acceleration. Saving geographical data makes it possible to change
the place of installation of the weighing equipment after external adjustment has
been carried out.
The adjustment of weighing equipment is valid at the place of installation and
within a specific tolerance zone. At 3000 e this zone extends ±100 km from the set
geographical latitude and ±200 m from the set elevation above sea level.
Installation Location in Germany An exception to this is the setting for “Germany (Zone D):” If during external
adjustment of weighing equipment within Germany the geographical data
– Geographical latitude: 51.00 degrees N
– 513 m elevation above sea level
are entered, the weighing equipment can be used throughout Germany.
Gravitational acceleration for “Germany (Zone D)” is 9.810 m/s

. On delivery the
geographical data for “Germany (Zone D)” are entered in the output device.
It is recommended to use the geographical data settings for “Germany (Zone D)”
when adjusting and delivering the weighing equipment within Germany. Entering
exact geographical data will lead to a higher level of accuracy but will also restrict
the tolerance zone.
Setup information – It is only possible to enter geographical data when the menu access switch is
open.
– When the Service mode is activated, you can enter geographical data in the
Setup menu under “WP-1" for the first weighing platform and COm1 / WP-2,
UNICOM / WP-2 or COm-WP for the second weighing platform. The settings are
made in the corresponding Setup menu under menu item 1.20.
– You can enter either the “geographical latitude in degrees" (LATITUD menu
item 1.20.1) and “elevation in m above sea level" (ALTITUD menu item 1.20.2),
or the value for gravitational acceleration (GRAVITY menu item 1.20.3).
Gravitational acceleration takes precedence over the geographical latitude and
elevation of the location: If it has been entered, input fields for latitude and
elevation show the values 99999.99 and 9999999 respectively. If only elevation
and latitude have been entered, 0000000 is displayed for gravitational
acceleration.

If you return to the highest level of the Setup menu without saving the configura-
tion parameter beforehand (save menu item 1.20.4) any settings that have been
made will be deleted.
