Improper Use; Warranty; Monitoring Of Test Resources - KERN VFB 2T-3 Betriebsanleitung

2.2 Improper Use

The weighing system is not suitable 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 weighing system.
(Example: Slowly draining fluids from a container on the weighing system.)
Do not leave permanent load on the loading fork. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
system, minus a possibly existing tare load, must be strictly avoided. The weighing
system could be damaged.
Never operate the weighing system in an explosive environment. The serial version
is not explosion protected.
Changes to the weighing system's design are not permitted. This may lead to
incorrect weighing results, safety-related faults and destruction of the weighing
system.
The weighing system unit may only be operated in accordance with the described
default settings. 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
• Improper setup or incorrect electrical connection
• The measuring system is overloaded

2.4 Monitoring of Test Resources

In the framework of quality assurance the measuring-related properties of the
weighing system 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.
