Basic Information (General); Intended Use; Improper Use; Warranty - KERN RIB Series Operating Instructions Manual

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 pan. 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". (Example: Slowly draining fluids from a
container on the balance.) Do not leave permanent load on the weighing pan. 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 or damage 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.
