3.2 Improper Use
Do not use these scales for dynamic weighing processes.
Do not leave continuous loads on the seating surface or weighing plate. This may
damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the seating
surface or the weighing plate, minus a possibly existing tare load, must be strictly
avoided. This could cause damage to the balance.
Never operate balance in explosive environment. The serial version is not explosion
protected. It should be noted that a flammable mixture of anaesthetics and oxygen or
laughing gas may occur.
Do not modify the construction of the scales. This may lead to incorrect weighing
results, safety-related faults and destruction of the balances.
The balances may only be used according to the described conditions. Other areas
of use must be released by KERN in writing.
Do not use the scales for determining body weight in medicine.
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
 Modification or opening of appliances
 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
 Dropping of scales
3.4 Monitoring of Test Resources
In the framework of quality assurance the measuring-related weighing properties of
the balances 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.
