3.2 Selecting the location
Measurement performance of your balance depends largely on the
surrounding environments.
Please follow these guidelines to make sure the proper environmental
conditions are met:
•Select a firm, horizontal location that is free from vibrations.
•Make sure that the ambient temperature is between 5°C and 30°C,
the relative humidity is around 50% and that non-condensing conditions
are met.
•Avoid direct sunlight and ensure that there are not any excessive
temperature fluctuations.
•Ensure the balance is places a sufficient distance from heat-sensitive
materials in the vicinity of the instrument.
•Avoid the effects of air currents from air conditioners, ventilators,
open doors, or windows.
•Keep away from objects or equipment that are magnetic or capable
of generating magnetic fields.
•Surroundings should be as free from dust as possible.
