1. Congratulations! English
In the seca 644 scale with standing aid, 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 644 scale with standing aid 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. In addition to the conventional determination of weight, the seca 644 also has a
function for determining body mass index. For this purpose, height is entered on the keypad and the body mass index associated with the weight value is output. You can use the pre-Tare function to record the weights of, e.g. three types of chair. This weight is automatically deducted in the weighing operation. The large, secure standing aid also enables persons who are unsteady on their feet to stand safely on the scale. 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 644 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 rechargeable batteries. 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 – 2,000 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 batteries are 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 batteries are 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. – Undo the locknuts using the four foot screws (1).

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 26). – Ask the patient to mount the scale. Once on the scale, the patient should stand still. – Read the weighing result off the digital display. – If a load greater than 300 kg or 660 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 (TARA) The Tare function is very useful if an additional weight, e.g. that of a chair, 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 chair) 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 place the patient on the scale. The patient may remain seated. 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 is stored until the scale 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 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. Three body sizes 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 BMI function FU 1. Activate the function by pressing the FUNC key once again. – An arrow on the left-hand side of the display 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 change the value in 1 cm increments using the arrow keys. – 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 29. – Press an arrow key if you would like to see the weight briefly. – 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 can be useful, for example, when the patient and the carer mount the scale together, and the weight of the carer is not meant to be shown. Three different tare weights (carer 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. An arrow on the left-hand side of the display 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 alter the weight of the patient using the arrow keys in display steps. – Once the correct value is set, press the FUNC key again. The pre-Tare function is now activated. – Mount the scale together with the patient. Read the weighing result off the digital display. – Press an arrow key if you would like to see the current weight value briefly. – To return to normal weighing mode, press the FUNC key. – To switch off the scale, press the Start key again.
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. Moving the scale For mobile deployment in a ward, the scale can be tipped backwards and moved about on the rollers. Important! The alignment of the base of the scale must be checked and corrected if necessary every time the location of the scale is changed.
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 for connecting the display to the scale correctly connected? – Switch the scale off for a few seconds. This can be done by opening the plug connected to the rechargeable battery block and unplugging the mains supply from the scale. … 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. Charge the rechargeable batteries in the next few days.

… batt appears in the display? – The rechargeable battery is so severely discharged that weighing is no longer possible. Recharge the battery. … 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 shows ? – 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.
