3.2 Improper Use
Do not use weighing system 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 unit. (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 weighing
plate, minus a possibly existing tare load, must be strictly avoided. Both, the weighing
plate and the display unit may be damaged during this process.
Never operate display unit in explosive environment. The serial version is not explosion
protected.
Changes to the display unit's design are not permitted. This may lead to incorrect
weighing results, safety-related faults and destruction of the display unit.
The display unit may only be operated in accordance with the described default
settings. 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 display
unit 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
display units’ test substances and the test weights required for this. In KERN’s
accredited DKD calibration laboratory test weights and display units may be calibrated
(return to the national standard) fast and at moderate cost.
