4 Basic Information (General)
4.1 Proper use
The balance purchased by you is intended to define the weighing value of weighed
goods. 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.
4.2 Improper Use
• Our balances are non-automatic balances, not provided for the use in dynamic
weighing processes. However, the balances can also be used for dynamic
weighing processes after verifying their individual operative range, and here
especially the accuracy requirements of the application.
• Do not leave permanent load on the weighing pan. This can damage the
measuring mechanism.
• Impacts and overloading exceeding the stated maximum load (max) of the
balance, minus a possibly existing tare load, must be strictly avoided. The
balance could be damaged.
• Never operate the 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.
4.3 Warranty
Warranty claims shall be voided in case:
• Our conditions in the operation manual are ignored
• The appliance is used beyond 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
4.4 Monitoring of Test Resources
Within the scope of quality assurance the metrological properties of the balance and
of an existing test weight must be checked at regular intervals. 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.
