2. BASIC INFORMATION
2.1. Intended use
Balance you ha
ve acquired serves to determine the weighing value of a load in
laboratory environment. It is intended for application as a non-automatic
weighing instrument only, i.e. the material to be weighed is manually and
carefully placed in the center of the weighing pa n. Weighing result should be
read only after stable reading has been obtained.
2.2. Inappropriate use
Do not use the balance as a dynamic weighing instrument. Even if small
quantities of weighed material are added or removed from the weighing pan of
the instrument, the reading should be taken onl y after stabilization of the r esult.
Do not place any magnetic materials on the weighing pan, as this can caus e
damage of the measuring system of the instrument.. Be sure to avoid impact
shock and overloading the balance in excess of the prescribed maximum load
rating, minus any possible tare weight that has been applied. Never use the
balance in an environment endangered b y an explosion. This balance has not
been adjusted for operation in explosive areas. There must not be any
modification made to the balance.
