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 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. 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

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.
