3.7 Leveling
Leveling for PMA.HD and Verified Models
Leveling the scale compensates for slant or unevenness at the
place of installation. The scale must be perfectly horizontal to
ensure consistent, reproducible weighing results.
The scale needs to be re-leveled and then adjusted if neces-
sary each time its setup location is changed.

t Turn the two leveling feet as
shown in the illustration until
the air bubble is centered within
the circle of the level indicator.
− Air bubble at “12 o'clock:” Turn
both feet clockwise.
− Air bubble at “3 o'clock:” Turn
the left foot clockwise and the
right foot counterclockwise.
− Air bubble at “6 o'clock:” Turn
both feet counterclockwise.
− Air bubble at “9 o'clock:” Turn
the left foot counterclockwise
and the right foot clockwise.
3.8 Warm-up Time
Using a Scale Verified for Use in Legal Metrol-
ogy:
Ensure that there is a warm-up time of at least
24hours after initial connection to the power
supply.
To ensure accurate results are
delivered, the scale must warm up
for at least 30minutes after initial
connection to the power supply.
Only then will the device have
reached the required operating
temperature.
4 Cleaning and
Maintenance
4.1 Cleaning
Before cleaning the AC adapter or the scale: Disconnect all
devices from the power supply.
WARNING Electrical Hazard from Voltage or
Current
Disconnect the AC adapter (if connected) from the mains.
Unplug any connected data cables from the PC. Never open
the scale or the AC adapter. The parts contained in these
cannot be cleaned, repaired or replaced by the operator.
NOTICE
Do not clean the following parts with acetone or aggressive
cleaning agents:
− Mains socket
− Data interface
− Labels, and all other plastic parts
Procedure
t Disconnect the device from the power supply.
t NOTICE Make sure that no liquid or dust gets into the
scale or the AC adapter.
t NOTICE Corrosion or damage to the device due to
unsuitable cleaning agents!
t Do not use corrosive, chloride-containing and aggres-
sive cleaning agents.
t Do not use cleaning agents that contain abrasive
ingredients, e.g. scouring agents, steel wool.
t Only use soft brushes and cloths for cleaning.
t Do not use solvent-based cleaning agents.
Cleaning the Control Panel
t Before cleaning the control panel: Turn off the device as
touching the screen could trigger unwanted inputs.
Cleaning the Device Housing
t Wipe off the housing with a slightly damp cloth. For more
severe contamination, use a mild soap solution.
t Wipe the device with a soft cloth.
4.2 Servicing
To ensure the continued accuracy of your scale, we recom-
mend scheduling regular servicing at least once a year.
Sartorius Service offers different service contracts with
maintenance intervals that are tailored to your needs.
A calibration certificate should always be issued as part of
every maintenance session. Safety inspections of the power
supply and its connections must be performed at appropriate
intervals by a qualified electrician (e.g. every two years).
