Operating environment

W A R N I N G
The instrument may not be used in dangerous environments.
The manufacturer and its suppliers reject any express or indirect guarantee for
use with high-risk activities.
N O T I C E
Protect the instrument from temperature extremes, including heaters, direct
sunlight and other heat sources.
Note the following points so that the instrument will operate perfectly and
have a long service life.
• Place the instrument firmLy on an even surface. Do not push any
objects under the instrument.
• The ambient temperature must be +15 to +40 °C (+60 to +104 °F).
• The relative humidity should be less than 80%; moisture should not
condense on the instrument.
• A minimum clearance of 15 cm (5.9 in.) must be ensured above and
on all sides of the device; this allows the air to circulate and
prevents overheating of the electric parts. The dosage arm of the
stepper motor must be able to move freely.
• Do not operate or store the instrument in extremely dusty, humid or
wet locations.
• Make sure that no liquids enter the instrument and immediately wipe
away any liquids that contact the instrument.
• Protect the instrument against vibrations, direct sunlight, corrosive
gases as well as strong magnetic and/or electric fields.
• Only use genuine replacement parts and accessories.
• Install the instrument in a levelled place and on a compact surface
to minimize the sound level of the instrument. This will avoid
undesired resonances that can increase the sound level.

• Keep the surface of the instrument and all accessories clean and
dry at all times. Splashes or spills on the instrument should be
cleaned up immediately.
The instrument must be serviced by the manufacturer's service
department at the prescribed intervals.
