3.0 SAFETY PRECAUTIONS
All safety messages are identified by the following words "WARNING" and
"CAUTION". These words mean the following:
WARNING Important information to alert you to a
situation that might cause serious
injury and damage to your property if
instructions are not followed.
CAUTION Important information that tells how to
prevent damage to equipment.
When using the balance, following safety precautions should always be followed
WARNING
Use the AC adapter designed by the manufacturer for the balance. Other
adapters may cause damage to the balance.
CAUTION
•Avoid installing the balance in direct sunlight- this may cause poor
performance or malfunctions.
•Do not mix different type of batteries. Replace all the batteries at the
same time.
•If the balance is not to be used for a long period of time, remove all
batteries from the battery compartment to avoid leakage which may
cause damage to the instrument.
•Avoid overloading or dropping material onto the platform as that
could damage the balance.
•Do not spill liquids on the balance as it is not water-resistant. Liquids
may damage the case and if it gets inside the balance it may cause
damage to the electronics.

•Material that has a static electric charge could influence the
weighing. Discharge the static electricity of the samples, if possible.

Another solution to the problem is to wipe both sides of the pan and
the top of the case with an anti-static agent.

5.0 PREPARATION
5.1 SETTING UP THE BALANCE
CAUTION
•Avoid installing the balance in direct sunlight that may cause poor
performance or malfunctions.
•Place the balance on a firm weighing table so that the balance is
levelled. The balance will not perform accurately when it is not
levelled.
•Level by adjusting the feet to centre the bubble in the spirit level.
•Remove the shipping protection screw and round cover as shown
below using the Allen key supplied in the box. (It is advisable to keep
the shipping protection screw and the round cover along with the
packing box for using during shipping to another location in future).
