21
Calibration/Adjustment
During calibration1), the span of the balance is adjusted to the changes in
ambient conditions.
You must adjust or calibrate your new balance at the place of installation after
each warmup period and before the first measurement. You must also re-adjust
or recalibrate your balance each time you set it up in a different area or when
ambient conditions change (especially the temperature). Verified balances
approved for use as legal measuring instruments must be adjusted/calibrated
at least once a day.
The balance offers you various adjustment and calibration functions. You can
select these functions by setting the appropriate menu codes. For more information,
refer to “Balance Operating Menu.”
You can interrupt any adjustment or calibration function by pressing c (10).
Using Verified Balances as Legal Measuring Instruments in the EU*:

Care and Maintenance
Servicing
Regular servicing of your balance by a Sartorius
technician will ensure its continued weighing
accuracy. Sartorius can offer you service contracts
with your choice of regular maintenance intervals
ranging from1month to 2 years.
Cleaning
Before cleaning the balance, unplug the AC adapter
from the wall outlet (mains supply).
Please do not use any aggressive cleaning agents
(solvents or similar agents). Instead, use a piece of
cloth which has been wet with a mild detergent (soap).
Make sure that no liquid enters the balance housing.
After cleaning, wipe down the balance with a soft,
dry piece of cloth.
Carefully remove any sample residue/spilled powder
by using a brush or a hand-held vacuum cleaner.
Make sure that no liquid or dust enters the crevice
surrounding the pan adapter.
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 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.
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 Unit. Only service technicians who are
authorized by Sartorius and who have access to the
required maintenance manuals are allowed to perform
maintenance and repairwork on the equipment.

Balance Operating Menu
In the operating menu, you can define how your
balance will adapt to ambient conditions and also
how it will work to meet your special requirements.
Changing Menu Code Settings
To select specific functions, you will need to set the
respective menu codes.
The keys have special functions for setting
menu codes:
q (9) = Increases a number by one with each
press (the numbers change in cycles)
t (6) = Confirms and stores a code setting; and
exits the menu
p (7) = Moves to the next of the three numbers
of a code (1st-2nd-3rd-1st, etc.)
The code for “automatic power-on” is 8 5 4.
