Care and Maintenance
Service
To ensure the continued accuracy of your balance, we recommend scheduling
regular servicing at least once a year. Sartorius Service offers different service
contracts with maintenance intervals that are tailored to your needs (see
www.sartorius.com/service). A calibration certificate should be issued as part
ofevery maintenance session. Have a qualified electrician inspect the technical
safety of the AC adaptor and its connections at appropriate intervals (e.g., every
two years).
Repairs
Repair work must only be carried out by trained service technicians. Never attempt
to repair the equipment when the power is turned on! Unplug the AC adaptor from
the electrical outlet (mains supply) beforehand. Repairs performed by untrained
persons will invalidate the warranty, and may result in considerable hazards for the
user and cause the balance to produce inaccurate results. Contact Sartorius Service
or a Sartorius dealer for the proper repair of your balance.
The device must be unplugged during repair work. Unplug the power cord.
Repairwork must only be performed by trained technicians.
