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

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.

prevent damage to equipment.
