2.1.1 Numeric input via navigation keys
Press ; current setting appears. The first digit is flashing and can be
changed.
If the first digit is not to be changed, press and the second digit will start
flashing. Each time you press , the display unit jumps to the subsequent
digit, returning to the first digit after the last digit has been pressed.
To change the selected (flashing) digit, press
repeatedly until the desired
value appears. Then select by using additional digits and change these by
using

3 Basic Information (General)
3.1 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.
3.2 Improper Use
Do not use display unit for dynamic weighings. 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 plate. 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.
3.3 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
3.4 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.
4 Basic Safety Precautions
4.1 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.
4.2 Personnel training
The appliance may only be operated and maintained by trained personnel.
5 Transportation & Storage
5.1 Testing upon acceptance
When receiving the appliance, please check packaging immediately, and the
appliance itself when unpacking for possible visible damage.
5.2 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 glass wind screen, weighing
platform, power unit etc. against shifting and damage.
6 Unpacking and implantation
6.1 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.
