NOTE: If calibration fails, ensure that the test area is free from drafts and the surface the scale

be an internal problem. To resolve internal problems, follow procedures in Chapters 2 and 3.

B.5 GEOGRAPHICAL ADJUSTMENT FACTOR (GEO)

The Geo Factor adjustment allows entry of values from 0 to 31 and is used to compensate for slight
variations in gravity at different geographical locations around the world.
This feature allows authorized personnel to accurately calibrate the scale at a location other than the
location where the scale is to be used. Prior to calibration, the Geo Factor is set to correspond to the
geographical location where the calibration is being performed. Following calibration, the Geo Factor
is changed to match the location where the scale is to be used. If required, the scale may also be
sealed according to the required approval regulations.
NOTE:
Only an authorized manufacturer's representative or certified verification personnel should
make these changes. Changing the Geo Factor alters the calibration values.
In the Service Menu, press No until GEO appears.
