9 2 Declaration of conformity To view the current EC/EU Declaration of Conformity go to: www.kern-sohn.com/ce 3 Basic directions (general information) 3.1 Intended use The scales are used for determining the body weight of people in the standing posi- tion. The person being weighed shall stand in the middle of the weighing surface and re- main calm. The value may be read after the scales stabilizes. The scales are designed for continuous use. Only those people who can stand on the scales platform with their both legs may enter it. The scales platform is equipped in the anti-slippery surface which shall not be taken off or covered during the time the people are being weighed.

10 3.2 Inappropriate use Do not use the scales for dynamic weighing. Do not leave a permanent load on the weighing plate. This can damage the measur- ing equipment. Be sure to avoid impact shock and overloading the scale in excess of the prescribed maximum load rating (max.), minus any possible tare weight that is already present. This could result in damage of the scale. Never operate the scale in hazardous locations. The series design is not explosion- proof. Attention should be paid that flammable mixture may also be formed from anaesthesiological means that contain oxygen or laughing gas (nitrous oxide). Construction alterations may not be made to the scale. This can lead to incorrect weighing results, faults concerning safety regulations as well as to destruction of the scale. The scale may only be used in compliance with the described guidelines. Other are- as of application/planned use must be approved by KERN in writing. Do not use the scales for determining body weight in medicine. 3.3 Guarantee The guarantee shall become void in the event of the following: • non-observation of our guidelines in the Operating Instructions, • use outside the described applications, • alteration to or opening the device, • mechanical damage or damage caused by media, liquids, • usual wear and tear, • inappropriate erection or electric installation, • overloading of the measuring equipment, • scale falling down.

11 3.4 Monitoring the test substances The metrology features of the balance and any possible available adjusting weight must be checked at regular intervals within the scope of quality assurance. For this purpose, the responsible user must define a suitable interval as well as the nature and scope of this check. 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. Test weights and balances can be adjusted quickly and at a reasonable price at KERN’s accredited DKD (Deutscher Kalibrierdienst) calibration laboratory (return to national standard). In the case of the scales for weighing people provided with the scale to determine a body size, it is recommended to carry out the check of its measuring accuracy be- cause determination of the human body size is always connected with a very large inaccuracy. 4 Basic safety directions 4.1 Observing the directions included in the Operating Instructions  Carefully read this operation manual before setup and commissioning, even if you are al- ready familiar with KERN balances.

12 5 Transport and storage 5.1 Check upon delivery Please check the packaging immediately upon delivery and the device during un- packing for any visible signs of external damage. 5.2 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.  Secure all parts such as the weighing platform, power unit etc. against shifting and damage.

13 6 Unpacking, installation and starting 6.1 Place of installation, place of use The scale is designed in such a way that reliable weighing results can be achieved under normal application conditions. By selecting the correct location for your scale, you will be able to work quickly and precisely. Therefore, please observe the following when choosing a place of installation: - Place the scale on a firm, level surface; - Avoid extreme heat as well as temperature fluctuation caused by installing the scale next to a radiator or in the direct sunlight; - Protect the scale against direct draughts due to open windows and doors; - Avoid shaking during weighing; - Protect the scale against high humidity, vapours and dust; - Do not expose the device to extreme dampness for longer periods of time. In- admissible bedewing (condensation of air moisture on the device) can occur if a cold device is taken into a significantly warmer environment. In this case, please keep the device for approx. 2 hours at room temperature after it has been disconnected from mains supply; - Avoid static charge build-up on the scale and people to be weighed; - Avoid contact with water. Major display deviations (incorrect weighing results) are possible if electromagnetic fields occur (e.g. coming from mobile phones or radio equipment) as well as due to static charging and instable power supply. It is necessary then to change the scale location or remove disturbance source. 6.2 Unpacking Carefully remove individual scale parts or the whole scale from its packaging and po- sition the scale in its intended working location. When the mains adapter is used, be careful not to cause the danger of falling over the power cable.

41 8 Using scale 8.1 Weighing  Switch on the scale with the [ON/OFF] key. The diagnostic scale self-check is performed and then the software version is displayed. The scale is ready for weighing when the „0,00 kg” weight display is shown. Direction: The [→0←] key makes it possible to zero the scale if necessary and at any time.  Place a person in the middle of the scale. Wait until the stability display (ο) is shown and then read the weighing result. Direction: If a person is heavier than the weighing range, the display will show the „Err” symbol (= overload). 8.1.1 Weighing with MWS Due to the great dimensions and the big weighing range especially suitable for weighing of immobile people on transportation stretchers, wheelchairs or overweight people in the adiposity range 8.1.1.1 Weighing with transportation stretcher or wheelchair  Place transportation stretcher/wheelchair with the person on the centre of the scales  Arrest the brakes of the transportation stretcher/of the wheelchair Do not leave the person unattended  When the person is lying/sitting quietly, read weighing value 1  Loosen the brakes and carefully pull off the transportation stretcher/wheelchair with the person  After that weigh the transportation stretcher/wheelchair without the person and subduct this weight from weighing value 1, from there results the person’s weight.

42 8.2 Taring The dead weight of any initial load used for weighing may be tared away by pressing the key, so that the following weighing shows the real weight of a person to be weighed.  E.g. when a rubber mat is put on the scale plate, the scale does not show 0 value.  To start the taring process, press the [TARE] key. Now internal weight saving is performed and value of 0.0 kg is displayed.  Place a person in the middle of the scale plate.  Then read the weight on the display. Direction: The scale can store only one tare value. When the scale is unloaded, the saved tare value is displayed with „negative” sign. To delete the saved tare value, unload the scale plate and then press the [TARE] key. 8.3 HOLD function The scale is provided with the integrated hold function (determination of average val- ue). It enables people to be weighed accurately although they are not still on the scale plate. Note: Determination of average value is not possible when a person moves too much.  Switch on the scale with the [ON/OFF] key. The diagnostic scale self-check is performed. The scale is ready for weighing when the „0.00 kg” weight display is shown.  Place a person in the centre of the scale plate.  Press the [HOLD] key. When the triangle is flashing on the display, the scale takes some measuring values and then the calculated average value is dis- played.  Press the [HOLD] key again to return the scale to the normal weighing mode.  Pressing the [HOLD] key makes it possible to activate the function at any time.

43 8.4 Mother/Child Function The “Mother/Child” function makes it possible to determine the body weight of infants and small children held in an adult’s arms.  Turn on the scales using the [ON/OFF] switch. The scales enters the self- diagnostic mode. The device is ready for operation as soon as “0.00 kg” is shown on the weight display.  Position the adult person in the middle of the scales platform. After showing the stability indicator, the scales displays the person’s weight. A triangle sym- bol is shown under the “WEIGHT” symbol.  Press the [TARE] button and the readout changes to “0.00 kg”.  Place the child in the arms of the adult person. After showing the stability indi- cator, the scales displays the child’s weight. The triangle symbol is now dis- played under the “NET” symbol.  Press the [TARE] button again and the readout again changes to “0.00 kg”.  After stepping off the scales, the total weight of the adult person and the child is displayed as a negative value.  Press the [TARE] button again. The saved tare value is cancelled and the scales can be used for weighing again. 8.5 Determination of Body Mass Index When you obtain a stable weight and display shows 0.0 kg, place a person in the middle of the scale plate. Wait until the weighing value is stable. Then press the BMI key. Now enter a body height. Please take note that reliable determination of BMI index is only possible for body height from 100 cm to 250 cm and weight > 10 kg. A body height entered as the last one is flashing on the display. Now you can enter a different value with the numerical keypad. Confirm the entered value with the ENTER key, and then a person’s BMI index will be displayed. When the BMI index value is displayed, it is presented with the arrow pointing the BMI symbol. To return to the weighing mode, press the BMI key once again and the arrow at the BMI symbol will disappear.

44 8.5.1 Classification of BMI values Classification of weight for adults over 18 years on the basis of Body Mass Index according to WHO, 2000 EK IV and WHO 2004 (WHO - World Health Organization). Category BMI (kg/m2) Risk of diseases accompanying overweight Underweight < 18.5 low Normal weight 18.5 – 24.9 average Overweight Preobesity I degree of obesity II degree of obesity III degree of obesity > 25.0 25.0 – 29.9 30.0 – 34.9 35.0 – 39.9 > 40 slightly increased increased high very high 8.6 PRE-TARE function When a tare weight (rubber mat, clothes, ...) is known, this value can be entered manually. If the PRE-TARE key is pressed shortly, the flashing display will be shown. The PRE-TARE function is active as long as the small arrow is pointing the ”PRE- TARE” symbol on the display. The value used as the last one will be displayed. If a different value is required, a new weight value can be entered with the numerical keypad. By pressing the ENTER key, the new value is confirmed and used. Then the entered value with minus sign will be shown on the display. When a person is placed on the scale plate, the display will show a weight value less the value entered previously. Pressing the PRE-TARE key again will return the scale to the normal weighing mode.

45 8.6.1 PRE-TARE function with 5 memories Owing to this function it is possible to store 5 Pre-Tare values (e.g. for different wheelchairs), and then call up them if necessary. Saving PRE-Tare values: To enable a later calling up values from the memory, they are to be entered into the memory first. It is carried out in the following way: The scale plate is unloaded, and the scale display is showing 0,0 kg. Put a weight, whose value is to be saved (e.g. an empty wheelchair), on the scale plate and wait until a stable weight display is shown. Press the M1-5 key repeatedly until the display will show the „ni” (M) symbol. Press the key with digit (1..5) shortly to indicate which number a value is to be saved under. The previously displayed weight value is flashing for 3 seconds. When the flashing is finished, press again the key with digit previously pressed and the weighing value is saved in the memory (short audible signal). By pressing the CLEAR key, the scale will return to the weighing mode without saving the value. The display will show the real value of the weight placed on the scale plate. When the weight is removed, the display will show 0,0 kg. Calling up the PRE-Tare value from memory: Press the PRE-Tare key repeatedly until the display will show the „ni” (M) symbol. Pressing the key with digit (1..5) will display the flashing weight value saved there. The small arrow, additionally shown on the display, is pointing to the „PRE-TARE” symbol. By pressing another key with digit (1..5), the appropriate also flashing weight value will be displayed. Press the ENTER key and the value will be accepted and shown on the display as the PRE-Tare value with minus sign. Now you can place e.g. a person in a wheelchair or on the transportation stretcher on the scale, and only a person‘s weight will be displayed. To return to the normal weighing mode when the scale plate is unloaded, press the PRE-Tare key shortly again. This will also result in disappearing the small arrow pointing the „PRE-TARE” symbol.

46 Printing Pre-Tare memory (refer also to section 8.6): To do this, press the PRE-Tare key repeatedly until the display will show the „ni” (M) symbol. Short pressing the PRINT key will activate printing of the values saved in 5 memo- ries. M1 0.0 kg M2 7.0 kg M3 10.0 kg M4 30.0 kg M5 50.0 kg 8.7 Printing function To use this function, you need the RS232 interface cable (available as accessories) which is connected with the round plug at the terminal back. Note: In medical applications, only the peripheral equipment meeting EN 60601-1 standard can be connected to the interface. When a scale is in the weighing mode, pressing the PRINT key will result in output of the particular data, presented below, via the interface. It is the standard way to output data, which cannot be changed.

47 9 Error messages The following messages can be shown on the display during switching on or using the scale. ERRL: Too small weight on the scale. ooooo: The scale plate was loaded during switching on the scale. Unload the scale plate. ERR: Overload, too large weight on the scale plate. 10 Service, maintenance, disposal 10.1 Cleaning Disconnect the unit from the mains power supply prior to cleaning, maintenance and repair activities. 10.2 Cleaning / Disinfecting Clean weighing platform (such as seat) as well as casing with household detergents or commercially available disinfectants, e.g. 70% isopropanol. We recommend a dis- infectant suitable for wiping disinfection. 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. To prevent cross-contamination (fungal skin infection) please observe the following time intervals for disinfection: • Weighing plate before and after any measurement with direct skin contact • When required: o Display o Foil-covered keyboard Do not spray disinfectants onto appliance. Make sure that disinfectant does not penetrate the interior of the balance. Remove dirt immediately. 10.3 Sterilisation Sterilisation of the appliance is not allowed. 10.4 Service, maintenance The device may only be operated and maintained by trained service technicians who are authorised by KERN. Disconnect the scale from mains supply before its opening.

48 10.5 Disposal Disposal of packaging and device must be carried out by an operator according to valid national or regional law of the location where the device is used.

49 11 Troubleshooting The scale should be switched off for a short time following an interruption in the pro- gram sequence and disconnected from mains supply. It is then necessary to repeat the weighing process from the beginning. Interruption Possible cause Weight display is not illumi- nated. • The scale is not switched on. • The mains supply connection has been interrupted (mains cable not plugged in/faulty). • Check the fuse of the mains adapter / green LED is illuminated next to the fuse. • Mains failure. • Batteries are incorrectly inserted or discharged. • No batteries. Weight display changes continuously • Draught/air movement • Table/floor vibrations • The weighing plate is in contact with foreign matters or is installed incorrectly. • Electromagnetic fields/static charging (choose a different location for the scale, switch off an inter- fering device if possible). The weighing result is obviously incorrect • The scale display is not set to zero • Incorrect adjustment. • Great fluctuations in temperature. • Warm-up time was ignored. • Electromagnetic fields/static charging (choose a different location for the scale, switch off an inter- fering device if possible). Should other error messages occur, switch the scale off and then on again. If the er- ror message remains, inform the manufacturer.
