RECOMMENDATIONS FOR A CORRECT USE OF THE BALANCE

2.1

PREFACE

In order to obtain accurate and repeatable weighing, please pay attention to the following.
2.2

FIRST POWER ON

 The first time that you connect the balance to the mains, before use, wait at least 12
hours to ensure the balance is fully warmed up.
 For a correct use of the balance, never disconnect the balance from the mains. If you
want to turn it off, use the ON / OFF button to put it in Stand-by. This ensures is not
necessary to wait 12 hours each time for the balance to warm up.
2.3

USING THE BALANCE

 Level the balance. It is vital, for correct weighing operation, to always level the balance:
regularly check that the bubble is at the center of the spirit level. Adjust then and lock
the feet to ensure the correct levelling of the balance.
 Always load the sample in the center of the pan to avoid possible errors.
 Only open the glass doors of the weighing chamber when necessary, and use tweezers
to load/unload the samples to be weighed, to avoid contamination of the sample.
 Pay attention to possible static charges, the static may occur due to containers made
from materials of low electrical conductivity or due to dry air with less than 40%
moisture. Electrostatic charges can alter the results of the weighing. It is recommended
to use the Adam Ioniser ABI-1 to eliminate static charges present on any substances
to be weighed or that have accumulated on the balance.
Because of static charges the results of weighings are always different and the balance
is not repeatable.

Pay attention to dynamic push: a big temperature difference between the sample to
be weighed and the weighing chamber creates air drafts along the sample. A colder
object appears heavier while a warmer object lighter, this effect is reduced when the
thermal equilibrium between sample and weighing chamber is reached.
With dynamic push you will get results that move in one direction depending on
whether the material is colder or warmer.
 Pay attention to substances that can evaporate (alcohol) or absorb humidity (silicone
gel), because with these types of materials weight may vary constantly in one direction.
 Be careful to magnetic materials, as magnetic objects will attract each other and the
force that results will be wrongly interpreted as a load.
With magnetic materials the weighing results are hardly repeatable, the indication
remains stable but weighing result provides different results.
