Care and Maintenance
Clearing
Wash down the scale with cleaning agents that you
commonly use in the food industry.
Important Note:
Featuring the IP 65 protection rating (approximately
equivalent to NEMA 4), the scale is dust-tight and
washdown-resistant. See the "Test Mark Award Cer-
tificate" issued by the TÜV, the German Association
for Technical Inspection.
Safety Inspection
lf there is any indication that safe Operation of the scale
with the power supply is no longer warranted, turn off the
power and unplug the scale from the power supply imme-
diately. Lock the scale in a secure place to ensure that it
cannot be used for the time being.
In this case, notify your nearest Sartorius Service Center
or the International Technical Support Group based in
Goettingen, Germany. Only Sartorius service technicians
who are authorized by Sartorius and have the proper
manuals are allowed to perform maintenance and repair
work on the scale.
Safe Operation of the scale with the power supply is no
longer ensured when
—
there is visible damage to the power supply
—
the power supply no longer functions properly
We recommend that the scale and power supply be
inspected according to the following checklist by a quali-
fied Sartorius service technician:
—
Leakage current <0.05 mA measured by a prop-
erly calibrated multimeter
—
Insulation resistance >7 megohms measured with
a constant voltage of at least 500 V at a 500
kohm load.
The duration and number of measurements should be
determined by a qualified Sartorius service technician
according to the particular ambient and operational condi-
tions. However, such inspection should be done at least
once a year.
