Entering Geographical Data
Purpose
To perform an external adjustment
of the weighing instrument at a place of
adjustment that is not the same as the
place of installation (e.g., at the factory
or on the dealer's premises). If the
weighing instrument is adjusted at the
place of installation, it is not necessary
to enter the geographical data.
The sensitivity of a weighing instrument
can change depending on its place of
installation, because it is affected by
local gravity – or, more precisely, by the
acceleration of gravity. When the geo-
graphical data is stored, the place of
installation can be changed following
external adjustment.
Calibration/adjustment of a weighing
instrument is valid at the place of
installation and within a specific toler-
ance range around that location. With
3000 e, for example, the tolerance zone
is ±100 km of the geographical latitude,
and ±200 m of the elevation above
sea level.
The following exception applies in
Germany (“Zone D"):
If the latitude and altitude are set to
– 51.00° North and
– 513 meters above sea level,
the weighing instrument can be used
anywhere in Germany. The acceleration
of gravity applicable for “Germany
(Zone D)" is 9.810 m/s
2
.
The geographical data stored in the
output device at the factory applies
to Germany (“Zone D").
This setting is recommended for cali-
brating/adjusting weighing instruments
to be used within Germany. Entering
more precise geographical data will
increase the weighing instrument's pre-
cision, but will also limit the tolerance
zone.
Note on Settings
– Geographical data can be entered
only in the service mode and only with
the menu access switch open.
– Enter geographical data 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 1.20.
– Enter either the geographical latitude
in degrees (menu item 1.20.1) together
with the altitude above sea level (menu
item 1.20.2), or enter the acceleration
of gravity (menu item 1.20.3).
If the acceleration of gravity has been
entered, then this value takes prece-
dence over the latitude and altitude;
in this case, “99999.99" and “9999999"
are displayed for latitude and altitude,
respectively. If only altitude and latitude
are entered, “0000000" is shown for the
acceleration of gravity.
!
If you return to the highest level of the
numeric menu without saving changes
(menu item 1.20.4), all changes made
up to that point are lost.
Procedure
– Open the menu access switch. If the
indicator is part of a verified weighing
system, the verification seal must be
broken to move the switch. Afterwards,
the weighing instrument must be
re-verified.
– Activate the service mode
– Select the weighing instrument
– Enter geographical data for the place of
adjustment under menu items 1.20.1
through 1.20.3 and select menu item
1.20.4 to save. This data can be
obtained from the relevant land registry
or Ordnance Survey.
– Perform external calibration/adjustment
(see page 20)
– Following calibration/adjustment,
enter the geographical data for the
place of installation under menu items
1.20.1 through 1.20.3 and select menu
item 1.20.4 to save.
– Close the menu access switch
– The weighing instrument can now be
used at the place of installation, or
anywhere within the tolerance zone.
Note:
To display geographical data during the
calibration/adjustment procedure, select
menu item 8.12.2 in the Setup menu,
under
Utilit (factory setting: 8.12.1,
geographical data not displayed).
When the display of geographical data
is active, the calibration procedure is as
follows:
When the calibration procedure is started
(
CAL ), the display shows ALTITUD for
2 seconds (if latitude and altitude are
used), followed by the configured value
(indicating meters above sea level).
Press
)
to confirm the data, or
(
to cancel. Next, the display shows
LATITUD
for 2 seconds, followed by the
value set for the geographical latitude
(in degrees). Again, press
)
to con-
firm the data or
(
to cancel. Next,
the prompt to place the adjustment
weight appears. If the acceleration of
gravity was entered rather than altitude
and latitude, the word “
GRAVITY
"
appears for 2 seconds, followed by the
value for the acceleration of gravity.
Press
)
to confirm the data, or
(
to cancel.
