3.2 Improper Use

Do not use these scales for dynamic weighing processes.
Do not leave permanent load on the balance. This may damage the measuring
system.
Impacts and overloading exceeding the stated maximum load (max) of the weighing
pan, 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 anesthetics and oxygen or
laughing gas may occur.
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.
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
 The appliance is modified or opened
 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 the balance

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.
For balances with height measuring rods, we recommend a metrological examination
of the accuracy of the height measuring rod, however, this is not mandatory as the
determination of human body height involves rather large, intrinsic inaccuracies.
