3 Basic Information (General)
Intended use
These balance is used to calculate the weight of people
standing upright in the private sphere. Utilisation of this
balance in the medical field is not permissible.
The person must step on the weighing plate for the weighing
procedure. As soon as a stable weighing value is reached the
weighing value can be read.
Non-intended
use
Do not use 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 permanent load on the weighing plate. This may
damage the measuring system.
Impacts and overloading exceeding the stated maximum load
(max) of the balance, minus a possibly existing tare load, must
be strictly avoided. This could cause damage to the balance.
Never operate balance in explosive environment. The serial
version is not explosion protected.
The structure of the balance may not be modified. This may
lead to incorrect weighing results, safety-related faults and
destruction of the balance.
The balance may only be used according to the described
conditions. Other areas of use must be released by KERN in
writing.

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 and damage caused by media, liquids
Natural wear and tear
The appliance is improperly set up or incorrectly electrically
connected
The measuring system is overloaded
Dropping the balance
Test device
control In the framework of quality assurance the measuring-related
properties of the balance 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 balance test
substances and the test weights required for this. In KERN’s
accredited DKD calibration laboratory test weights and
balances may be calibrated (return to the national standard)
fast and at moderate cost.
4 Basic Safety Precautions
Carefully read this operation manual before setup and
commissioning, even if you are already familiar with KERN
balances.
5 Transportation & Storage
Testing upon
acceptance When receiving the appliance, please check packaging
immediately, and the appliance itself when unpacking for
possible visible damage.
Packing/
Return
transport
ÖKeep all parts of the original packaging for a possibly
required return.
ÖOnly use original packaging for returning.
ÖPrior to dispatch disconnect all cables and remove
loose/mobile parts.
ÖSecure all parts e.g. powerpack against slipping and
damage

Installation
location,
Deployment
location
The balance is designed in a way that reliable weighing results
are achieved in common conditions of use. You will work
accurately and fast, if you select the right location for your
balance.
On the installation site observe the following:
Place scales on a stable, even surface
Maintain a gap of 30 cm on all sides away from walls and
other objects or obstacles.
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, vapors and
dust;
Do not expose the device 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 the balance and of the person to be
weighed.
Avoid contact with water.
If electro-magnetic fields or static charge occur, or if the power
supply is unstable major deviations on the display (incorrect
weighing results) are possible. In that case, the location must
be changed.
Unpacking Remove the individual components of the balance or the
complete balance from the packaging with care and install at
the intended location.
