4 Basic Information (General)
Weighing instruments have to be verified for the purposes stated
below in accordance with Directive 2009/23/EC. Article 1,
paragraph 4. “Determination of mass in the practice of medicine
that is, weighing patients for reasons of medical supervision
during medical surveillance, examination and treatment.”
Determining the body weight in the medical practice area.
Use as „non-standalone weighing scale“, that is, a person
sits carefully onto the seating surface’s centre. Once a
steady display value is shown, you can read the weight
value.
No contraindication known
The instruments shall only be used by people who can sit still.
The chair scales may not be used for the transport of people!
As long as the patient is sitting on the chair scales, the wheel
brakes must be locked without fail.
Do not step onto the foot rests when stepping or leaving the
chair scales!
4.1 Specific function
4.2 Proper use
These scales are used to determine weight of people sitting at rest in medical
treatment rooms. The scales are suitable for recognising, preventing and controlling
illnesses.
The person should be weighed carefully and have contact with the center of the seat,
sit and stay calm.
As soon as a stable weighing value is reached the weighing value can be read.
The scales are designed for long-term usage.
The balances should be checked for correct condition prior to each utilisation by a
person familiar with proper operation of the balance.
MCC-M-BA-e-1312 11
4.3 Improper Use
Do not use these scales for dynamic weighing processes.
No permanent load on the seat area. This may damage the measuring system.
Impacts and overloading exceeding the stated maximum load (max) of the seating
surface, 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.
4.4 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
4.5 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.
