3 Fundamental information (general)
3.1 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 placed in the centre of the
weighing plate. The weighing value can be read off after a stable weighing value has
been obtained.
3.2 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: Slowly
draining fluids from a container on the balance.)
Do not leave a permanent load on the weighing plate. This can damage the
measuring system.
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.
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.
3.3 Guarantee
The guarantee is not valid at the 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
PLS/PLJ/ALS/ALJ-BA-e-0819
43
3.4 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 monitoring of balance test substances and the test
weights 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).
4 Fundamental safety information
4.1 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.
4.2 Staff training
The device may only be operated and looked after by trained members of staff.
5 Transport and storage
5.1 Acceptance check
Please check the packaging immediately upon delivery and the device during
unpacking for any visible signs of external damage.
5.2 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. weighing plate,
mains power supply etc. against slipping and damage.
PLS/PLJ/ALS/ALJ-BA-e-0819

6 Unpacking, installation and commissioning
6.1 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 location for your balance, you will be able to work quickly and
precisely.
Therefore please observe the following at the place of installation:
• Place the balance on a firm, level surface;
• 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 mains.
• Avoid static charging of items to be weighed, or weighing container.
Major display deviations (incorrect weighing results) are possible if electromagnetic
fields occur as well as due to static charging, currents and instable power supply. It is
then necessary to change the location.
6.2 Unpacking
Carefully remove the balance from its packaging, remove the plastic wrapping and
position the balance in its intended working location.
