When a weighing terminal is to be reinstalled at a different geographic location, gravitational and altitude
changes can be accounted for by the following steps.
Note that this procedure is not necessary if an on-site adjustment is performed.
Determining the Geo code value
There are two methods to determine the Geo code value for your location.
Method A
1 Go to https://www.welmec.org/welmec/gravity-information/
for your specific geographic location.
2 Check the METTLER TOLEDO Geo code Table A to select the Geo code according to your g value,
e.g. Geo code 20 should be applied if your g value is 9.810304.
Method B
Use the METTLER TOLEDO Geo code Table B to determine the Geo code for the new altitude and location
where the scale will be used.
The latitude and height above sea level can be found using this link https://www.mapcoordinates.net/en.
Checking the Geo code value in the instrument
Comparing Geo codes
1 Compare the determined Geo code with the current Geo code setting of the weighing terminal.
2 If the two Geo code values do not match, call the METTLER TOLEDO service technician.
When the system is certified, a re-verification will be necessary.
Note
Using the Geo code value for calibration adjustment is not as accurate as re-applying certified test weights and
re-calibrating the scale in a new location.
