4 Basic Information (General)

4.1 Documentation

These installation instructions contain all data necessary for placing and
commissioning the weighing bridges KERN KFD V20.
In combination with a display unit, described below as weighing system, for operation
configuration, please refer to the operating instructions of the display unit.

4.2 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.

4.3 Improper Use

Do not leave permanent load on the weighing bridge. This may damage the
measuring system.

Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. The weighing
system could be damaged.
Never operate in an explosive environment. The serial version is not explosion
protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the balance.
The weighing system unit may only be operated in accordance with the described
default settings. Other areas of use must be released by KERN in writing.

4.4 Warranty

Warranty claims shall be voided in case

• Our conditions in the operation manual are ignored

• The appliance is used outside the described uses

• Structural changes of the device

• Mechanical damage and damage caused by media, liquids

• Natural wear and tear

• The appliance is improperly set up or incorrectly electrically connected

• Overload of the measuring system
