3 Basic Information (General)
3.1 Proper use
The balance you purchased is intended to determine the weighing value of 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. As soon as a stable weighing value is reached the weighing value can be read.
3.2 Improper Use
Do not use balance 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 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. Balance may be
damage by this.
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.
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 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

CB/FCB-BA-e-0640 9
3.4 Monitoring of Test Resources
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
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 Transport and 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
Keep all parts of the original packaging in case you need to return the appliance.
Only use original packaging for returning.
Before sending, disconnect all connected cables and loose/movable parts.
Attach possibly existing transport safeguards. Secure all parts, e.g. weighing plate,
power unit etc., to prevent slipping and damage.

6 Unpacking, Setup and Commissioning
6.1 Installation Site, Location of Use
The balances are 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.
Therefore, observe the following for the installation site:
•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. 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 charging of the material to be weighed, weighing container and
windshield.
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.
6.2 Unpacking
Carefully remove the balance from the packaging, remove plastic cover and setup
balance at the intended workstation.
6.2.1 Setup
The balance must be installed in a way that the weighing plate is exactly in horizontal
position.
