6 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.” 6.1 Specific function Indication • • Determining the body weight in the medical practice area.
6.3 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.

10 Unpacking, Setup and Commissioning 10.1 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.
10.3 Scope of delivery Serial accessories: 10.3.1 MPC models • Balance • Power pack unit (EN 60601-1 attestation of conformity) • • Operating instructions Wall bracket • Protective working cover 10.3.2 MPE-HM models • Balance • Power pack unit (EN 60601-1 attestation of conformity) • Operating instructions • • Height measuring stick Protective working cover 10.3.
10.4.2 MPE models (Example shown for MPE-HM model) Scope of delivery: Fig.
Refitting Procedure: Mount tripod (1) on tripod holder (2) at weighing platform Ensure that the cable (3) does not get clamped! Fasten tripod, using 4 screws 10.5 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.
10.6 Battery operation is possible by obtaining an optional battery power pack. MPC 1 MPE 1 Open the battery compartment cover (1) at the base of the display unit and insert the rechargeable battery. Charge the battery for at least 12 hours before initial use. The appearance of the symbol in the weight display indicates that the battery is almost exhausted. The weighing scale will remain ready for operation for a few more minutes before switching off in order to save battery (s. chap. 11.6 Auto off).
10.7 Battery operation As an alternative to rechargeable battery operation, the balance may also be operated with 6x AA batteries. Open battery compartment cover (1) at the lower side of the display unit and insert batteries according to the example below. Lock the battery cover again. If the batteries are empty, in the balance display appears the symbol . Change batteries. To save battery power, the balance switches off automatically (see chap.11.6 Auto off). Capacity of batteries exhausted.
Insert batteries Version A: Remove the battery compartment cover and detach the adhesive tape carefully. Ensure that the cables are not destroyed. Insert contact sheet and sink the battery compartment connection into the provided opening (see fig. below) Contact sheet Plug for rechargeable battery connection Opening for rechargeable battery connection (Should the rechargeable battery be used later, take care that the plug does not disappear in the housing) Clamp the contact sheet acc.
Version B: Remove battery compartment cover Connect battery holder to housing contact acc. to illustration Insert battery holder Insert batteries into battery compartment and lock with battery compartment cover. 10.8 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).
11 Operation 11.1 Weighing Start balance by pressing 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. • However, you can reset the weighing scale to zero by pressing the key. Have person stand in the centre of the scales. Wait until the standstill display „STABLE“ appears, then read the weighing result. • If the person is heavier than the weighing range, "OL" (=overload) will appear in the display. 11.
11.2.1 Subsequent tare weight The balance can be tared several times successively. 11.3 HOLD function The balance has an integrated standstill function (mean value calculation). With this function it is possible to weigh people accurately even if they do not stand still on the weighing plate. Start balance by pressing . Wait for stability display „STABLE to appear. Press (MPE) (MPC) in the display „---------“ will appear and the „HOLD“ symbol appears.
11.5 Calculation of the Body Mass Index You need to know a person’s body height before you can calculate the BMI for that person. It should either be known or can be determined directly with the MPE-HM model. 11.5.1 Measuring body height (MPE-HM only) Push measuring stick upwards and set the stopper horizontally. Push measuring rod carefully down until the headpiece touches the person’s head. (It is recommended to take measurements with shoes removed).
Read body height on measuring stick. 11.5.2 Calculating Body Mass Index Start balance by pressing Wait for stability display „STABLE to appear. Press (MPE) or (MPC). The most recently entered body height will be shown with the enable digit flashing. The „BMI“ symbol lights up. To enter body height, press the and Confirm your entered value by pressing key. (MPE) or (MPC). BMI „0.0“ is displayed Allow the person to step onto the centre of the weighing platform.
• • Reliable calculation of BMI is restricted to a body height of 100 cm to 200 cm and a weight of >10 kg. If weighing has to take place under unsteady conditions, you can be stabilise the display by applying the Hold function. 11.5.3 Classification of BMI values Weight classification for adults over 18 years of age using the BMI in accordance with WHO, 2000 EK IV and WHO 2004. Categorie BMI ( kg/m2) Risk of diseases associated with overweight Underweight < 18.5 low Normal weight 18.5 – 24.
11.6 Automatic switch-off function „AUTO OFF“ The weighing scale will switch off automatically after the allotted time as long as neither the display unit nor the weighing plate is operated. • Menu settings: [F1 oFF] [oFF 0/3/5/15/30] (see chap. 12) Start balance by pressing . Wait for stability display „STABLE to appear.
11.7 Display background illumination • Menu settings: [F4 bk] [bL on / bL oFF / bL AU] see chap. (12) • Menu settings:MPC: [F4 or F2 bk] [bL on / bL oFF / bL AU] see chap.

12 The menu Access to service menu „tCH“is locked in verified weighing scales. To disable the access lock, destroy the seal and actuate the adjustment switch. For position of adjustment switch, see chap. 16. Attention: After destruction of the seal the weighing system must be re-verified by an authorised agency and a new verification wire/seal mark fitted before it can be reused for applications subject to verification. 12.

15 Service, maintenance, disposal 15.1 Cleaning Before any maintenance, cleaning and repair work disconnect the appliance from the operating voltage. 15.2 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.
16 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 • The balance is not switched on. not glow. • The mains supply connection has been interrupted (mains cable not plugged in/faulty). • Power supply interrupted.
17 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.
