Care and Maintenance
Cleaning
Before cleaning the balance, unplug the AC adapter from the wall out-
let.
Please do no use any aggressive cleaning agents (solvents or similar
agents). Instead, use a piece of cloth wet with a mild detergent.
Make sure that no liquid enters the balance housing.
After cleaning, wipe down the balance with a soft, dry piece of cloth.
Safety Inspection
lf there is any indication that safe Operation of the balance with the
AC adapter is no longer warranted, turn off the power and unplug the
balance from AC power. Lock the balance and AC adapter in a secure
place to ensure that they cannot be used for the time being.
Safe Operation of the balance with the AC adapter is no longer en-
sured when
- there is visible damage to the AC adapter
- the AC adapter no longer functions properly
- the AC adapter has been stored for relatively long periods un-
der unfavorable conditions
In this case, notify your nearest Sartorius Service Center or the Inter-
national Service Support Department in Goettingen, Germany. Only
service technicians who have access to the required maintenance
manuals are allowed to perform maintenance and repair work on the
equipment.
We recommend the balance along with the AC adapter be inspected
according to the following checklist by a qualified Sartorius service
technician:
- Leakage current < 0.05 mA measured by a properly calibrated
multimeter
- Insulation resistance > 7 megohms measured with a constant
voltage of at least 500V at a 500 kohm load
