4 Basic Information (General)
4.1 Proper use
This weighing scale is designed for determining the weight of a person whilst standing or
sitting.
On multifunctional weighing scales, the weighed person should carefully step onto the center
of the weighing platform and remain standing without moving. If weighed with a wheelchair,
the wheelchair should remain in the center of the weighing plate.
As soon as a stable weighing value is reached the weighing value can be read.
The weighing scale is designed for continuous duty.
4.2 Improper Use
Do not use these scales for dynamic weighing processes.
Do not leave permanent load on the weighing plate. 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. 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.
The balance cannot be used to determine a body weight in practice of medicine.

4.4 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.
