MWB-SH-e-1810.docx 94 Basic Information (General)4.1 Proper useThis weighing scale is designed for determining the weight of a person whilst standing orsitting.On multifunctional weighing scales, the weighed person should carefully step onto the centerof 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 UseDo not use these scales for dynamic weighing processes.Do not leave permanent load on the weighing plate. This may damage the measuringsystem.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 thebalance.Never operate balance in explosive environment. The serial version is not explosionprotected. It should be noted that a flammable mixture of anesthetics and oxygen or laughinggas may occur.The structure of the balance may not be modified. This may lead to incorrect weighingresults, safety-related faults and destruction of the balance.The balance may only be used according to the described conditions. Other areas of usemust be released by KERN in writing.The balance cannot be used to determine a body weight in practice of medicine.4.3 WarrantyWarranty 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 scales4.4 Monitoring of Test ResourcesIn the framework of quality assurance the measuring-related weighing properties of thebalances and, if applicable, the testing weight, must be checked regularly. The responsibleuser must define a suitable interval as well as type and scope of this test. Information isavailable on KERN’s home page (www.kern-sohn.com) with regard to the monitoring ofbalance test substances and the test weights required for this. In KERN’s accredited DKDcalibration laboratory test weights and balances may be calibrated (return to the nationalstandard) fast and at moderate cost.
