4.2  Selecting a Setup Location
Select the right setup location: 
 − Set up the device on a stable, even surface that is not exposed to vibrations.
 − Maintain free access to the device at all times.
Choose a location that is not subject to the following negative influences:
 − Heat (heater or direct sunlight)
 − Drafts from open windows, AC systems and doors
 − Extreme vibrations during weighing
 − Heavy “traffic areas” (personnel)
 − Extremely high humidity
 − Electromagnetic fields
 − Extremely dry air
Acclimatization
Condensation from humidity can form on the surfaces of a cold device when it 
is brought into a warm area. You should therefore let a device acclimatize for 
approximately two hours disconnected from its power source before reconnecting 
it to the supply voltage.
Seal on Scales Verified for Use in Legal Metrology:
Legislation requires that a seal be affixed to verified scales. On Sartorius devices, this 
seal takes the form of a sticker with the “Sartorius” logo. If the seal is removed, the 
validity of verification will become void and you must have your scale re-verified. 
The verification supplied here is for verified weighing instruments for use in the EEA. 
Please keep it in a safe place.
