4 Basic Information (General)
4.1 Proper use
The display unit acquired by you is used in combination with a weighing plate and
serves to determine the weighing value of material to be weighed. It is intended to be
used as a “non-automatic weighing system”, i.e. the material to be weighed is
manually and carefully placed in the centre of the weighing plate. As soon as a stable
weighing value is reached the weighing value can be read.
4.2 Improper Use
Do not use display unit 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 display unit. (Example: Slowly
draining fluids from a container on the balance.)
Do not leave permanent load on the weighing pan. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
plate, minus a possibly existing tare load, must be strictly avoided. Both, the weighing
plate and the display unit may be damaged during this process.
Never operate display unit in explosive environment. The serial version is not
explosion protected.
Changes to the display unit's design are not permitted. This may lead to incorrect
weighing results, safety-related faults and destruction of the display unit.
The display unit may only be operated in accordance with the described default
settings. Other areas of use must be released by KERN in writing.

4.3 Warranty
Warranty claims shall be voided in case
•Our conditions in the operation manual are ignored
•The appliance is used outside the described uses
•The appliance is modified or opened
•Mechanical damage or damage by media, liquids, natural wear and tear
•The appliance is improperly set up or incorrectly electrically connected
•The measuring system is overloaded
4.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related properties of the display
unit and, if applicable, the testing weight, must be checked regularly. The responsible
user must define a suitable interval as well as type and scope of this test. Information
is available on KERN’s home page (www.kern-sohn.com with regard to the
monitoring of display units’ test substances and the test weights required for this. In
KERN’s accredited DKD calibration laboratory test weights and display units may be
calibrated (return to the national standard) fast and at moderate cost.
5 Basic Safety Precautions
5.1 Pay attention to the instructions in the Operation Manual
Carefully read this operation manual before setup and
commissioning, even if you are already familiar with KERN balances.
All language versions contain a non-binding translation.
The original German is binding.
5.2 Personnel training
The appliance may only be operated and maintained by trained personnel.

6 Transport and storage
6.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
6.2 Packaging / return transport
Keep all parts of the original packaging for a possibly
required return.
Only use original packaging for returning.
Prior to dispatch disconnect all cables and remove
loose/mobile parts.
Reattach possibly supplied transport securing devices.
Secure all parts such as the glass wind screen, the
weighing platform, power unit etc. against shifting and
damage.

7 Unpacking and placing
7.1 Installation Site, Location of Use
The display units are designed in a way that reliable weighing results are achieved in
common conditions of use.
Precise and fast work is achieved by selecting the right place for your display unit
and your weighing plate.
On the installation site observe the following:
•Place the display unit and the weighing plate on a stable, even surface.
•Avoid extreme heat as well as temperature fluctuation caused by installing
next to a radiator or in the direct sunlight;
•Protect the display unit and the weighing plate against direct draft from open
windows or doors.
•Avoid jarring during weighing;
•Protect the display unit and the weighing plate against high humidity, vapours
and dust.
•Do not expose the display unit to extreme dampness for longer periods of
time. Non-permitted condensation (condensation of air humidity on the
appliance) may occur if a cold appliance is taken to a considerably warmer
environment. In this case, acclimatize the disconnected appliance for ca.
2 hours at room temperature.
•Avoid static charge of goods to be weighed or weighing container.
Major display deviations (incorrect weighing results) may be experienced should
electromagnetic fields (e.g. due to mobile phones or radio equipment), static
electricity accumulations or instable power supply occur. Change location or remove
source of interference.
