seca 664 Instruction manual and guarantee Oct 2006 Rev G

1. Congratulations! English

In the seca 664 electronic wheelchair scale, you have purchased a high-precision yet sturdy piece of equipment. seca has been putting its experience at the service of health for over 150 years now, and as market leader in many countries of the world, is always setting new standards with its innovative developments for weighing and measuring. In accordance with national regulations, the seca 664 electronic wheelchair scale is used primarily in hospitals, doctors’ surgeries and in-patient nursing facilities. The weight display can be switched between kilogrammes (kg), pounds (lbs) and stones (sts). Weight is determined within a few seconds.

You can use the pre-Tare function to record the weights of, e.g. three types of wheelchairs. This weight is automatically deducted in the weighing operation. The two fold-away ramps allow the wheelchair-user to get on and off in comfort. The fold-away column allows the scale to be stored upright to save space. The scale is of a very sturdy construction and will give you long and loyal service. It is easy to operate and the large display is easy to read. The seca 664 can be moved on castors and its low power consumption combined with its rechargeable batteries mean it will provide long, mobile service.

Power supply The scale is powered by a mains unit and by a rechargeable batterie. The scale works independently of the mains, which is very handy for mobile use. The LC display and the evaluation electronics have a low power consumption – 2000 weighing operations can be performed with a fully charged battery. Once battery voltage is no longer adequate, the battery symbol first appears in the display to indicate that battery power is dropping. If the batterie is not charged, battery voltage will ultimately not be adequate for error-free measuring. In this case, bAtt appears in the display and weighing is no longer possible. The rechargeable batterie is charged by the mains unit supplied. For this purpose, the mains unit needs to be connected to the mains for at least 24 hours. Please use only the mains unit supplied or mains units from the seca range of accessories. Before plugging the unit into the socket, check whether the mains voltage marked on the mains unit matches local mains voltage.

4. Setting up and aligning the scale – Place the scale on a level surface. – Fold the column upwards. Secure the column by tightening up the knurled screw. – Undo the locknuts using the four foot screws. – Align the scale by undoing the foot screws. The air bubble in the spirit level must be right in the centre of the circle. – Then re-tighten the locknuts. – Fold down the ramps required. – Ensure that only the feet of the scale are in contact with the floor. The scale may not be in contact at any other point.

Correct weighing – Press the Start key with no load on the scale. se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. The scale is then automatically set to zero and ready to use. – If necessary, switch the weight display (see page 18). – Move your chair onto the scale and keep still. – Read the weighing result off the digital display. – If a load greater than 360 kg or 800 lbs is placed on the scale, St0P appears in the display. – To switch off the scale, press the Start key again.

Switching the weight display The weight display can be switched between kilogrammes (kg) and pounds (lbs) or between kilogrammes (kg) and stones (sts). – Switch on the scale using the green Start key. Weight is initially displayed in the last setting selected. – To switch the weight display between kilogrammes and pounds, press the kg/lbs/sts key. The kg or lbs display lights up.

– To switch weight display between pounds and stones, hold down the kg/lbs/sts key for approx. 2 seconds. – The lbs or sts display lights up.

Automatic switch-off/economy mode The scale automatically detects whether it is being operated on rechargeable batteries alone or whether it is connected to the mains. – With rechargeable battery operation: automatic shut-down after 5 minutes. – With mains operation: shut-down only via keypad.

Taring weight display (TARE) The Tare function is very useful if an additional weight, e.g. that of a wheelchair, is to be ignored for weighing purposes. Proceed as follows: – Press the Start key with no load on the scale. – First place the additional weight (e.g. the wheelchair) on the scale and activate the Tare function by pressing and holding the HOLD/TARE key. The display is reset to zero. 0.0 appears in the display. The note “NET” appears. – Now move the patient and the wheelchair previously weighed onto the scale. The scale determines the patient’s weight. You can now perform as many weighing operations as you like. – Hold the key down again to deactivate the Tare function; the scale is then back in normal weighing mode and the tare value has been erased. – The tare value is likewise erased by the scale being switched off.

Store weight value (HOLD) You can also continue displaying the weight determined once the load has been removed. This makes it possible to look after a patient first, before having to note the weight. – Press the HOLD/TARE key whilst the load is on the scale. “HOLD” appears in the digital display. The value remains saved in the display until the hold function is automatically switched off. – The HOLD function can be switched off by pressing the HOLD key again. 0.0 appears in the display if the scale has no load on it, otherwise the current weight. The “HOLD“ display vanishes.

Note: The HOLD and TARE functions can also be used simultaneously.

Body-Mass-Index (BMI) Body Mass Index puts height and weight in relationship to one another, providing more accurate information than ideal Broca weight, for example. A tolerance range is given which is considered ideal for health. – Press the Start key with no load on the scale. se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. The scale is then automatically set to zero and ready for operation. – Press the FUNC key. The last function used appears in the display. – Use the arrow keys to select the BMI function, FU 1. Activate the function by pressing the FUNC key again.

The last memory used appears in the display. An arrow on the left-hand side of the display also indicates which memory is set. Use the arrow keys to select the memory position under which you wish to record – or under which you have already recorded – the patient’s height. Press the FUNC key again. The patient’s recorded height will then appear on the display. You can use the arrow keys to adjust the value in increments according to the graduations displayed. Once the correct value is set, press the FUNC key again. The BMI function is now activated. Ask the patient to mount the scale. Once on the scale, the patient should stand still. Read off the BMI on the digital display and compare it with the categories on page 21. To return to normal weighing mode, press the FUNC key.

– To switch off the scale, press the Start key again.

Evaluating Body Mass Index for adults: Compare the value determined with the categories quoted below which correspond to those used by WHO, 2000. • BMI below 18.5: Warning, this patient weighs too little. There could be a tendency to anorexia. An increase in weight is recommended to improve well-being and performance. If in doubt, consult a specialist. • BMI between 18.5 and 24.9: The patient is of a normal weight. He can stay as he his. • BMI between 25 and 30 (pre-obese): The patient is slightly to moderately overweight. He should cut his weight if he is already ill (e.g. diabetes, hypertension, gout, fat metabolism disorders). • BMI over 30: Weight reduction is essential. Metabolism, cardiovascular system and bones are all under strain. A consistent diet, plenty of movement and behavioural training are all recommended. If in doubt, consult a specialist.

Weighing with pre-Tare If the pre-Tare function is activated, a stored weight value is deducted from the currently measured weight. This function is useful, for example, if the weight of a wheelchair is not to be displayed. Three different tare weights (wheelchair weights) can be stored. – Press the Start key with no load on the scale. se(a, 8.8.8.8.8. and 0.0 appear consecutively in the display. After that, the scale is automatically set to zero and ready for operation. – Press the FUNC key. The last function used appears in the display. – Use the arrow keys to select the preTare function FU 3. Activate the function by pressing the FUNC key once again. The last memory used appears in the display. An arrow on the left-hand side of the display also indicates which memory is set. – Use the arrow keys to select the desired memory for storing the additional weight or where a weight may already be stored. – Then press FUNC. In the display you will see the tare value from the memory.

– You can use the arrow keys to adjust the value in increments according to the graduations displayed. – Once the correct value is set, press the FUNC key again. The pre-Tare function is now activated. – Move onto the scale in the wheelchair associated with that memory. Read the weighing result off the digital display. – To return to normal weighing mode, press the FUNC key. – To switch off the scale, press the Start key again. Tip: note weight and the memory in which the weight is stored on your wheelchairs.

Setting damping Damping is useful for reducing weight determination malfunctions (due to patient movements, for example). The stronger the damping, the more slowly the weight display reacts. You can set damping to suit requirements. – Press the FUNC key and keep it depressed for 2 seconds. FIL and the current setting appear in the display: 0 = slight damping ➞ fast determination of weight 1 = average damping ➞ normal determination of weight 2 = strong damping ➞ slow determination of weight – Press an arrow key if you want to change the set value. – Press the FUNC key again to store the displayed value. The scale is then back in normal weighing mode. The settings are retained even once the scale is switched off.

6. Storing the scale The scale can be stored upright to save space. – Undo the knurled nut on the hinge of the column. – Pull out the knurled screw and fold over the column. – Re-engage the knurled screw. – You can now prop the scale up on the column. – The scale can now be moved. The scale can be placed on the bottom rail for short-term storage. Secure the scale so that it does not fall over when stored in the upright position.

7. Cleaning Clean the rubber surface and the housing as required using a domestic cleaning agent or commercially-available disinfectant. Follow the manufacturer’s instructions. Under no circumstances use abrasive or acid cleaners, white spirit, benzene or the like for cleaning. Such substances can damage the high-quality surfaces.

8. What do I do if… … no weight display comes on? – Is the scale switched on? – Check the mains connection and the connection of the battery pack – Is the plug contact on the scale correctly connected? – Is the plug contact for connecting the display to the scale correctly connected? … 0.0 does not appear before the weighing operation? – Press the Start key again – there must not be any load on the scale – and only its feet should be in contact with the floor. … one segment is illuminated constantly or not at all? – The relevant segment has a fault. Inform Servicing. … the display shows ? – Battery voltage is dropping.

… the display flashes? – If you have just activated the Hold or Tare function, please wait until the scale has detected a steady weight value. The display will then stop flashing. – If there has been no activation of a function beforehand, remove the load from the scale and wait until 0.0 is displayed, then weigh again. … the display appears? – The ambient temperature of the scale is too high or too low. Place the scale in an ambient temperature between +10 °C and +40 °C. Wait about 15 minutes for the scale to adapt to the ambient temperature and then weigh again. … the display E and a number appear? – Switch off the scale with the Start key and start the scale again. The scale will then work normally again. If this is not the case, interrupt the power supply by briefly removing the rechargeable battery. If this measure is equally unsuccessful, inform the Service department.

9. Maintenance Your seca scale leaves the factory with an accuracy greater than ± 0.15 %. To ensure that this degree of accuracy is maintained, the product must be carefully set up and regularly serviced. Depending on frequency of use, we recommend servicing at intervals of 3 to 5 years. Please note that a qualified servicing agent should be used for this. If you are in doubt, seca Customer Service will give you more information.
