3 Basic Information (General)

3.1 Intended 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.
