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.”
4.1 Specific function
Indication
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.
Contraindication
No contraindication known
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 instruments shall only be used by people who can sit still.
The balances should be checked for correct condition prior to each utilisation by a person familiar with proper operation of the balance.
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!
12 MCC-M-BA-e-1211
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.
