2 Basic Information (General)

It is absolutely necessary that you read and understand the operating instructions prior to
installation and commissioning and follow the instructions during the process!

2.1 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.

2.2 Improper 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 sys-
tem.
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 pro-
tected.
The structure of the balance may not be modified. This may lead to incorrect weighing re-
sults, 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.

2.3 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

2.4 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 de-
fine 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. Our accredited DKD calibration laboratory
offers fast and inexpensive adjustment for test weights and weighing balances (reset to na-
tional normal weight).
