Care and Maintenance

Cleaning

Please do not use any aggressive cleaning agents (solvents or similar
agents). Instead, use a piece of cloth that has been wet with a mild
detergent to clean the scale. Make sure that no liquid enters the scale
housing. After cleaning, wipe down the scale with a soft, dry piece of
cloth.

Safety Inspection

lf there is any indication that safe Operation of the scale with the AC
adapter/power supply is no longer warranted, turn off the scale and
disconnect the equipment from AC power immediately. Lock the
equipment in a secure place to ensure that it cannot be used for the
time being.
In this case, notify the Sartorius Service Center or International Tech-
nical Support Group based in Goettingen, Germany. Only service
technicians who are authorized by Sartorius and have access to the
required manuals are allowed to perform maintenance and repair
work on the equipment.
Safe Operation of the scale with the AC adapter/power supply is no
longer ensured when
there is visible damage to the AC adapter/power supply
the AC adapter/power supply no longer functions properly
the AC adapter/power supply has been stored for relatively
long periods under unfavorable conditions
the AC adapter/power supply has been exposed to rough
handling during shipment
We recommend that the scale along with the AC adapter/power sup-
ply be inspected by a qualified Sartorius service technician according
to the checklist given below.
Leakage current <0.05 mA measured by a properly calibrated
multimeter
Insulation resistance >7 megohms measured with a constant
voltage of at least 500 V at a500kohmload.
The duration and number of measurements should be
determined by a qualified Sartorius service technician
according to the particular ambient conditions
and operational conditions of the AC adapter. Such
inspection should be done at least once a year.
