Care and Maintenance
Service
Regular servicing by a Sartorius technician will extend the service life of your
weighing platform and ensure its continued weighing accuracy. Sartorius can
offer you service contracts, with your choice of regular maintenance intervals
ranging from 6 months to 2 years.
Cleaning
Before cleaning the weighing platform, disconnect it from the power supply
(e.g., unplug the AC adapter).
To clean the weighing platform when it has been exposed to dry ambient
conditions:
– Use a piece of cloth dampened with a commercially available cleaning
agent to wipe down the weighing platform
Wet Environment:
To clean the weighing platform when it has been in a wet environment:
– Use a commercially available cleaning agent and hose down the platform
afterwards.
In conformance with the IP65 protection rating, the weighing platform is
washdown resistant.
However, the applicable standards (EN 60529 and, in Germany, DIN VDE
0470 T1) do not allow the use of pressurized water (such as strong jets of
water using a hose or high-pressure cleaning equipment). When spraying
down the weighing platform, avoid directing strong jets of water at the 4
silicone gaskets beneath the load plate so that they are not torn by the water
pressure.
Never use concentrated acids, bases, solvents or pure alcohol to clean the
weighing platform!
Corrosive Environment
To clean the weighing platform exposed to a corrosive environment:
– Regularly remove all traces of corrosive substances from the platform
– Follow the manufacturer’s directions provided for the disinfectants and
cleaning agents you use to clean the weighing platform
Important Note:
If the water that you use to clean the weighing platform is too hot or too cold,
the difference in temperature between the water and the platform can cause
condensation within the platform. This condensation may cause the weighing
platform to malfunction.
Safety Inspection
If there is any indication that safe operation of the weighing platform is no
longer warranted, turn off the power and disconnect it from the power supply
immediately. Lock the equipment is a secure place to ensure that it cannot be
used for the time being.
Safe operation of the weighing platform with the AC adapter is no longer
ensured when
– there is visible damage to the AC adapter
– the AC adapter no longer functions properly
– the AC adapter has been stored for a relatively long period under adverse
conditions
