Care and Maintenance
Safety Inspection
If there is any indication that safe operation of the balance is no longer warranted:
t
Disconnect from the supply voltage: Unplug the power cord from the outlet.
t
Secure the AC adapter and cord so that they cannot be used.
Safe operation of the mass comparator with the AC adapter is no longer ensured
when:
– The AC adapter or the mains connecting lead shows visible damage.
– The AC adapter no longer functions properly.
– Following extended storage in adverse conditions.
In this case, notify the Sartorius Service Center.
Maintenance and repair work may be performed only by authorized service techni-
cians who have access to the required maintenance manuals and instructions and
who have received the necessary training.
We recommend that the AC adapter be inspected by a qualified service technician
with regard to the following:
– Leakage current: <0.25 mA measured with a properly calibrated multimeter.
– Insulation resistance >
S Ohm as measured with a constant voltage of at least
500 volts at a 500 kOhm load.
The duration and number of checks should be determined by a qualified Sartorius
service technician on site based on specific ambient and operating conditions
(once a year as a minimum).
