Safety Inspection
If there is any indication that safe
operation of the balance with the AC
adapter is no longer warranted:
Turn off the power and discon-
nect the equipment from AC
power immediately
> Lock the equipment in a secure
place to ensure that it cannot be
used for the time being
Safe operation of the balance
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
unfavorable conditions
In this case, notify your nearest
Sartorius Service Center or the

may only be performed by service
technicians who are authorized
by Sartorius and who
