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.
4.3 Improper Use Do not use these scales for dynamic weighing processes. Do not leave permanent load on the weighing pan. 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.
5 Basic Safety Precautions 5.1 Pay attention to the instructions in the Operation Manual Carefully read this operation manual before setup and commissioning, even if you are already familiar with KERN balances. All language versions contain a non-binding translation. The original German is binding. 5.2 Personnel training The medical staff must apply and follow the operating instructions for proper use and care of the product. 5.
6 Electromagnetic compatibility (EMC) 6.1 General hints The installation and use of this electrical medical device requires special precautionary measures as outlined in the EMC information below. This device complies with the limits set for medical electrical devices of group 1, class B (as per EN 60601-1-2). Electromagnetic compatibility (EMC) describes a device‟s ability to perform reliably within an electromagnetic environment without causing inadmissible electromagnetic interference at the same time.
6.2 Electromagnetic interferences Guidelines and manufacturer’s declaration – electromagnetic interferences The personal scale MPD-M is designed for use in an electromagnetic environment that meets the requirements stated below. The customer or user of the medical electrical device must ensure that operation takes place in such an environment.
6.3 Electromagnetic noise immunity Guidelines and manufacturer’s declaration - electromagnetic noise immunity The personal scale MPD-M is designed for use in an electromagnetic environment that meets the requirements stated below. The customer or user of the medical electrical device must ensure that operation takes place in such an environment.
Guidelines and manufacturer’s declaration - electromagnetic noise immunity The personal scale MPD-M is designed for use in an electromagnetic environment that meets the requirements stated below. The customer or user of the medical electrical device must ensure that operation takes place in such an environment. Noise immunity tests IEC 60601 test level Conformity Electromagnetic environment guideline Conducted HF disturbance variables 3 150 kHz to 80 MHz 3V 3 80 MHz to 2.
6.3.1 Crucial features of performance Note: The personal scale MPD-M does not have any crucial features of performance as per IEC 60601-1. The system may be subject to interference by other devices even if these devices conform to current emission requirements as per CISPR. 6.
7 Transport and storage 7.1 Testing upon acceptance When receiving the appliance, please check packaging immediately, and the appliance itself when unpacking for possible visible damage. 7.2 Packaging / return transport Keep all parts of the original packaging for a possibly required return. Only use original packaging for returning. Prior to dispatch disconnect all cables and remove loose/mobile parts. Reattach possibly supplied transport securing devices.
8 Unpacking, Setup and Commissioning 8.1 Installation Site, Location of Use The balances are designed in a way that reliable weighing results are achieved in common conditions of use. You will work accurately and fast, if you select the right location for your balance.
8.4 Placing Level balance with foot screws until the air bubble of the water balance is in the prescribed circle. Check levelling regularly. 8.5 Mains connection Power is supplied by the external power unit which also serves to isolate the mains supply from the scale. The stated voltage value must be the same as the local voltage. Always use genuine approved KERN power pack units as per EN 60601-1 directive.
Voltage has dropped below prescribed minimum. Rechargeable battery very low. Rechargeable battery completely reloaded If the balance is not used for a longer time, take out the rechargeable battery and store it separately. Leaking liquid could damage the balance. 8.7 Initial Commissioning In order to obtain exact results with the electronic balances, your balance must have reached the operating temperature (see warming up time chap. 1).
9 Operation Turn on weighing scale by foot switch (chap. 3). The balance will carry out a self-test The scales are ready for operation as soon as the weight display for “0.0 kg“ has appeared. Have person stand in the centre of the scales. Wait until the standstill display „STABLE“ appears, then read the weighing result.
11 Service, maintenance, disposal 11.1 Cleaning Before any maintenance, cleaning and repair work disconnect the appliance from the operating voltage. 11.2 Cleaning / disinfecting Clean weighing platform (such as seat) as well as casing with household detergents or commercially available disinfectants. Please follow manufacturer‟s instructions. Do not use abrasive or aggressive cleaners such as spirits or alcohol or similar as they might damage the high-quality surface.
12 Instant help In case of an error in the program process, briefly turn off the balance and disconnect from power supply. The weighing process must then be restarted from the beginning. Fault Possible cause The displayed weight does not glow. The balance is not switched on. The mains supply connection has been interrupted (mains cable not plugged in/faulty). Power supply interrupted.
13 Verification General introduction: According to EU directive 2009/23/EC balances must be officially verified if they are used as follows (legally controlled area): a) For commercial transactions if the price of goods is determined by weighing. b) For the production of medicines in pharmacies as well as for analyses in the medical and pharmaceutical laboratory. c) For official purposes d) For manufacturing final packages In cases of doubt, please contact your local trade in standard.
Position adjustment switch and seals: 1 1 2 3 1. 2. 3. Self-destroying seal mark Cover Adjustment switch 13.
14 Adjustment As the acceleration value due to gravity is not the same at every location on earth, each display unit with connected weighing plate must be coordinated - in compliance with the underlying physical weighing principle - to the existing acceleration due to gravity at its place of location (only if the weighing system has not already been adjusted to the location in the factory).
Procedure: Switch off the balance. Press adjustment switch and turn on weighing scale by operating foot switch (chap. 3).. Wait until the size of the adjustment weight (see chap. 1) required is displayed. Place adjustment weight in the centre of the weighing platform. Wait until „Ld 0“ is shown. Take away adjustment weight. Ensure that there are no other objects on the weighing pan. Wait for a few seconds until „PASS“ is displayed.
