1. Congratulations! English
By purchasing the seca 684 multifunctional scales 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 684 multifunctional scales is used primarily in hospitals, doctors’ surgeries and in-patient nursing facilities. The folding seat integrated into the robust handrail makes the seca 684 suitable not only for weighing patients seated in a
wheelchair but also for weighing people who easily lose their balance. The seca 684 is designed to measure weight conventionally but can also determine body mass index. A membrane keyboard allows body size to be entered for obtaining the body mass index that corresponds with weight. 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 684 can be moved on castors.

Caution! Push the bolt beneath the seat so it does not extend out. Only load the seat with a weight up to the permissible highest level (150 kg). To raise the folding seat: 1. Lift the folding seat up. 2. Fasten the folding seat by turning the bolt counterclockwise. Make sure that the seat is correctly locked into place. Make sure that the seat is not accidentally unlocked.
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/SET key for about 2 seconds. Depending on the version of the scale, the year will appear immediately or additional menu items will appear. If additional menu items appear, use the arrow keys to select the TIME menu item and then press the FUNC/SET key to reach the settings menu. The year appears in the display. – Use the arrow keys to set the correct year. – Press the FUNC/SET 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/SET 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/SET 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/SET key. As soon as the set minute starts, press the FUNC/SET 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 30). – Stand on 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 pounds (lbs) 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.

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 flashes in the display until weight is detected to be stable. Only then is the Tare function fully activated. 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 is stored until the HOLD function switches off automatically. – The HOLD function can be switched off by pressing the HOLD/TARE 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.

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 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 33. To return to normal weighing mode, press the FUNC key. To switch off the scale, press the START key again.
Evaluating the 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 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. 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.
7. 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. … 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.
