Introduction
1.3 Putting into operation
1.3.1 Selecting or changing the location
The correct location is crucial to the accuracy of the weighing results!
Major geographical
location changes
The manufacturer adjusts each scale to the local gravity conditions (GEO value). In
the event of major geographical location changes, this setting must be adjusted by a
service technician. Certified scales must also be recertified observing the national cer-
tification regulations. These steps are not necessary for scales with an internal cali-
bration weight.
Select a stable, vibration-free and if possible a horizontal location.
The ground must be able to safely bear the weight of the fully loaded scale.
Observe the following environmental conditions:
• No direct sunlight
• No strong drafts
• No excessive temperature fluctuations
Aligning the scale
Only scales that have been aligned precisely horizontally provide accurate weighing
results. The certified scales have a spirit level to simplify alignment.
Turn the adjustable feet of the scale until the spirit level’s air bubble is inside the
inner circle.
