seca 656 Instruction manual and guarantee March 2009

1. Congratulations! By purchasing the seca 656 electronic platform scale you have acquired a highly accurate and 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 656 electronic platform 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 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 656 can be moved on castors.

Displaying time After the scale has been switched on, time is displayed for about 2 seconds. If a printer is connected, the time and date of the weighing operation is printed out in addition to the weight itself. Depending on the country to which it is supplied, the display can be in either 24-hour clock format (e.g. 19:45) or in 12-hour format (e.g. P 7:45). If TIME appears in the display and 3 alarm signals are heard after the scale is switched on, this means that the scale has been without a power supply for a prolonged period, so the clock needs to be reset.

Setting the clock – To reach setting mode, press the FUNC key for about 2 seconds. Use the arrow keys to select the TIME menu item and then press the FUNC key to reach the settings menu. The year appears in the display. – Use the arrow keys to set the correct year. – Press the FUNC key to confirm the year information entered. This simultaneously switches you to the next value you can set. Change this value too using the arrow keys and confirm the entry using the FUNC key. Set all the values for the clock correctly in the same way. The sequence of values is year, month, day, hour, minute. On clocks with a 12-hour display, A appears on the left of the display for morning times and P for afternoon and evening times. – After you have confirmed the minutes using the FUNC key, you exit the settings menu automatically and the clock continues to run at the time set. If you also require seconds to be set accurately, then proceed as follows: – set a minute which is still to come, but do not confirm it using the FUNC key. As soon as the set minute starts, press the FUNC key. At that point, the clock will start running at 00 seconds and the set minute.

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 24). – Stand on the scale and keep still. Note The maximum load on each individual corner of the weighing platform is 200 kg. – 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.

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

Memory function (TARE) The new kind of memory function on this scale means that the Tare function can also be used to determine patient weight if the additional weight (such as a stretcher or wheelchair) cannot be weighed separately beforehand. If a patient is brought into A&E, for example, he is placed on the scale still on the stretcher and the memory function is activated. Once the patient has been looked after, the empty stretcher (together with all the other items which were used for emergency medical treatment) is put back on the scale to determine patient weight. Proceed as follows: – Press the Start key with no load on the scale. – Put the patient on the scale with the stretcher or the wheelchair and activate the Tare function by pressing and holding HOLD/TARE. The display is reset to zero, 0.0 flashes in the display until weight is detected to be stable. Only then is the Tare function fully activated. The note “NET” appears. – Now take the patient off the scale and look after him. The display now shows total weight (patient plus additional load) as a negative value. This value is stored until the Tare function is switched off. – Once you have looked after the patient, put the empty stretcher back on the scale (together with any equipment or blankets which were used for emergency medical treatment). The additional weight is now deducted from the stored total weight, giving you the patient’s weight (likewise displayed as a negative value). – 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. Note: You can of course also use the Tare function in the usual manner to tare an additional weight (e.g. a wheelchair) beforehand, so as to obtain patient weight directly when weighing the patient together with the additional weight.

Model 656

GB 25

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 is stored until the HOLD function switches off automatically. – 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 function can also be used if the TARE function has been executed beforehand.

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 27. – 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. 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 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. Press the FUNC key again. 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. Secure the scale so that it does not fall over when stored in the upright position. – Remove the mains unit plug from the mains socket. – Remove the mains unit plug from the connecting socket on the scale. – Press the locking mechanism on the Western plug and remove the plug from the socket on the electronics box. – Fold up the ramps.

GB 29

– Carefully pick up the scale by the handles and move it using the castors on the other side of the scale. When moving the scale, always hold it firmly in both hands. The scale is easy to steer by the centre castor.

7. Cleaning Clean the 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? – Is the plug contact of the mains unit properly connected to the scale? – Is the plug contact for connecting the display to the scale correctly connected? … 0.0 does not appear before weighing? – 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. … St0p appears in the display? – Maximum load has been exceeded. … 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.

30

… 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, disconnect the power supply by briefly removing the mains unit. If this measure is equally unsuccessful, inform the Service department.
