For this purpose enter in the Func menu (access authorization required !):
•
”LAt” = the latitude
•
”ALt” = the height above sea level in multiples of 100 m (e.g. 12 = 1200 m
above sea level).
A prerequisite for the correction calculation is that the values of the calibration
location are entered before the calibration with calibration weights.
The values for Darmstadt are set ex works: ”LAt” = 50, ”ALt” = 1.
When calibrating at another place, these values must be adapted correspond-
ingly (firstly set ”LAt” and ”ALt”, then calibrate).
On a change of location, then only the new values have to be entered. If ”LAt”
and ”ALt” do not correspond to the actual location when calibrating, errors
arise at the new location, even if the scale displays correctly in the calibration.
The correction calculation cannot be used then, instead of this the scale must
be calibrated with weights at the new location. The correct settings before and
after the calibration are in the responsibility of the scale operator or installer.
The correction calculation can be deactivated with the setting ”LAt” = 91. The
display is then always related to the location of the last calibration.
6.6 Access authorization
Data relevant to calibration (e.g. the nominal load and load unit of the scale)
as well as the calibration should be protected against unauthorized changing.
For this purpose the corresponding menu items can be locked by setting the
”LocPA” parameters in the
Func menu to 1. When the menu is called up
again, the corresponding subitems no longer appear or cannot be changed. In
order to obtain access nevertheless, the concealed calibration button must be
pressed before the parameter menu is called up. The button is accessible
through the opening on the left below on the front of the unit (see 3.1.1 ) and
can be activated with a pointed object. In operation the opening must be
closed with the enclosed adhesive mark or in the case of legal for trade appli-
cations with the calibration mark. ”LocPA” can also no longer be reset without
activating the button.
If the scale is protected in this way, access to the data relevant to legal for
trade applications is possible:
•
after activating the concealed button
or
•
with a computer (serial interface) after entering the password
