15.0 SAFETY AND MAINTENANCE
CAUTION
Use the AC adapter designed by the manufacturer for the balance. Other
adapters may cause damage to the balance.
Avoid overloading or dropping material onto the platform which 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.
16.0 TROUBLE-SHOOTING
Service of a PGW balance will generally be necessary when the balance
does not perform as expected. The balances are not user-serviceable. For
Service Information, see section 18.0 and contact Adam equipment or your
supplier.
Problems usually fall into one of the following categories:
User Problems:
The user is asking the balance for something it cannot do or is confused by
the modes and functions of a balance. It is also possible the user has set a
parameter that has affected the balance operation. Resetting the parameter
to a normal value will restore operation.
Mechanical Problems
The balances consist of complicated and fragile mechanical devices. They
can be damaged by placing a weight on it which is too high for the balance or
by dropping the balance or occasionally shipping it without taking care. The
most fragile parts are the flexures. Dust, dirt, spills and other foreign objects
in the balance can also cause problems.
