Weighing range
2 Fundamental information (general)
2.1 Intended use
The balance you have acquired serves to determine the
weighing value of the material to be weighed. It is intended to
be used as a "non-automatic" balance, i.e. the material to be
weighed is manually and carefully attached at the balance. The
weighing value can be read off after a stable weighing value
has been obtained.
2.2 Inappropriate use
Do not use the balance for dynamic weighing. In the event that
small quantities are removed or added to the material to be
weighed, incorrect weighing results can be displayed due to the
"stability compensation" in the balance. (Example: Slow flow of
liquids from a container suspended from the balance).
Do not suspend a permanent load from the balance This can
damage the measuring equipment (Risk of fracture). Be sure
to avoid impact shock and overloading the balance in excess of
the prescribed maximum load rating (max.), minus any
possible tare weight that is already present. This could cause
damage to the balance(danger of fracture).
Important:
Always make sure that there are no living beings or
-
materials below the load that could be injured or
damaged!
The balance is not suitable for weighing living beings.
-
Do not use as baby scales!
The balance does not comply with the medical
-
product law (MPG).
Never operate the balance in hazardous locations. The series
design is not explosion-proof. Structural alterations may not be
made to the balance. This can lead to incorrect weighing
results, faults concerning safety regulations as well as to
destruction of the balance. The balance may only be used in
compliance with the described guidelines. Varying areas of
application/planned use must be approved by KERN in writing.
2.3 Guarantee
The guarantee is not valid following
-
non-observation of our guidelines in the operating
instructions
- use outside the described applications
- alteration to or opening of the device
- mechanical damage and damage caused by media, liquids
- natural wear and tear
- inappropriate erection or electric installation
- overloading of the measuring equipment
2.4 Monitoring the test substances
The metrology features of the balance and any possible
available adjusting weight must be checked at regular
intervals within the scope of quality assurance. For this purpose,
the answerable user must define a suitable interval as well as the
nature and scope of this check. Information is available on
KERN's home page (www.kern-sohn.com) with regard to the

required for this. Test weights and balances can be adjusted
quickly and at a reasonable price in KERN's accredited DKD
calibration laboratory (return to national normal).
3 Fundamental safety information
3.1 Observe the information in the operating instructions
Please read the operating instructions carefully before erecting
and commissioning, even if you already have experience with
KERN balances.
3.2 Staff training
The device may only be operated and looked after by trained
members of staff.
4 Transport and storage
4.1 Acceptance check
Please check the packaging immediately upon delivery and the
device during unpacking for any visible signs of external
damage.
4.2 Packaging
Please retain all parts of the original packaging in case it
should be necessary to return items at any time.
Only the original packaging should be used for return
consignments. Before despatch, disconnect all attached
cables and loose/movable parts. Apply any intended transport
security devices. Secure all parts, e.g. glass windshield,
weighing plate, power unit etc., to prevent slipping and
damage.
5 Unpacking, installation and commissioning
5.1 Place of installation, place of use
The balance is constructed in such a way that reliable weighing
results can be achieved under normal application conditions.
By selecting the correct application location for your balance,
you will be able to work quickly and precisely.
Therefore please observe the following at the application
location:
•
Avoid extreme heat as well as temperature fluctuation
caused by installing next to a radiator or in the direct
sunlight;
•
Protect the balance against direct draughts due to open
windows and doors;
•
Avoid jarring during weighing;
•
Protect the balance against high humidity, vapours and
dust;
•
Do not expose the device to extreme dampness for longer
periods of time. Inadmissible bedewing (condensation of air
moisture on the device) can occur if a cold device is taken
into a significantly warmer environment. In this case,
please acclimatise the device for approx. 2 hours at room
temperature after it has been disconnected from the
batterys.
•
Avoid static charging of the material to be weighed,
weighing container and windshield.
Major display deviations (incorrect weighing results) are
possible if electromagnetic fields occur as well as due to static
