1. GENERAL INFORMATION
1.1 INTENDED USE
The balances are designed to provide accurate measurement of weighed loads, performed under
laboratory conditions.
1.2 PRECAUTIONS
•Prior to first use, it is highly recommended to carefully read this User Manual, and operate
the balance as intended.
•Do not use the balance for a dynamic weighing. Even if small quantities of weighed material
are added or removed from the weighing pan of the instrument, the reading should be taken
only after stabilization of the measurement results.
•Do not place any magnetic materials on the weighing pan, as this can cause damage to the
measuring system of the instrument.
•While loading the balance make sure that load is placed in the very center of the weighing
pan.
•Make sure the load does not exceed instrument’s measuring range (maximum capacity).
•Do not leave heavy loads on the weighing pan for a long period of time.
•In case of failure, immediately unplug the instrument.
•Balances to be decommissioned, should be decommissioned in accordance with valid legal
regulations.
•Do not use the balance is areas endangered with explosion. The balance is not designed to
operate in EX zones.
1.3 SUPERVISION OVER METROLOGICAL PARAMETERS
Metrological parameters of a balance need to be checked by an authorized user. Inspection
frequency is qualified by the ambient conditions in which a balance is used, processes carried out
and adopted quality management system.
1.4 WARRANTY CONDITIONS
A. Schuler Scientific will exchange, replace or repair the existing balance for any damage that
appears to be faulty by production or by construction within the 5-year warranty period.
B. Warranty is voided if:
•mechanical defects caused by inappropriate use:
•defects of thermal and chemical origin,
•defects caused by lightning, overvoltage in the power network
•defects caused by water damage
•or other random event
•overloading the mechanical measuringsystem
•installing another version of the operating system
•utilizing the balance contrary to its intendeduse
•repairs carried out by non-authorized service centers
•removing or destroying protective stickers which secure the balance’s housing against
unauthorizedaccess
C. Warranty card must be filled out for warranty to be valid.

9
2. UNPACKING AND INSTALLATION
2.1 PLACE OF USE AND ASSEMBLING
•The balance should be stored and used in locations free of vibrations and shakes, free of air
movement and dust.
•Ambient air temperature should not exceed the range of: +10 °C ÷ +40 °C. Ambient relative
humidity should not exceed 80%. During balance operation, ambient temperature in the
weighing room should not change rapidly.
•Place the balance away from heat sources. Avoid exposing the balance to the sunilight.
•Take special precaution when weighing magnetic objects, as part of the balance is a strong
magnet. Should such loads be weighed, use under-pan weighing option, which removes the
weighed load from area influenced by the balance’s magnet. The hook for under-pan
weighing is installed in balance’s base.
