1. Congratulations! English

By purchasing the seca 675 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 675 platform scale is used primarily in hospitals, doctors’ surgeries and in-patient nursing facilities. The scales are a Class I medical product, and have been calibrated in accordance with the precision class III.

The seca 675 has two weighing ranges which can be selected. Weighing range 1 has a reduced maximum capacity but greater display resolution, whilst weighing range 2 allows you to use the maximum load capacity of the scale. Weight is determined within a few seconds. Using the Pre-Tare function, you can store the weight of a wheelchair. 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 675 can be moved on castors.

Checking that the contents of the calibration counter are correct This seca scale is calibrated. Calibration may be performed only by authorised centres. To ensure this, the scale is fitted with a calibration counter which records any change to data relevant to calibration. If you want to check whether the scale is properly calibrated, proceed as follows: – If necessary, switch off the scale. – Keep any key depressed and start the scale. The current contents of the calibration counter are shown on the display for a few seconds. – Compare the output contents of the calibration counter with the number shown on the calibration counter sticker. For valid calibration, both numbers must match. If sticker and calibration counter do not match, then re-calibration is reBoth numbers must match. quired. Contact your service agent or seca Customer Service. If a supplementary calibration is necessary, then the supplementary calibration mark illustrated opposite is used to record the calibration counter position instead of the seca calibration mark shown above. This mark is secured with an additional seal by the person authorised to perform the supplementary calibration. The supplementary calibration mark is available from seca Customer Service under the number 14-05-01-886.

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. – Switch weighing range if necessary (see page 25). – 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.

24

– If a load greater than 200 kg or 300 kg is placed on the scale, St0P appears in the display. – To switch off the scale, press the Start key again.

Switching the weighing range The seca 665 has two weighing ranges which can be selected. Weighing range 1 has a reduced maximum capacity but greater display resolution, whilst weighing range 2 allows you to use the maximum load capacity of the scale. Depending on the application in question, you decide whether you would prefer to use the fine display resolution or the high load range. – Switch on the scale at the green Start key. The scale initially operates in the weighing range last selected. – To change the weighing range, press the key . – A triangle in the display indicates the weighing range active in each case. This remains active even when the scale is turned off.

Note: It is possible to switch from Range 1 with fine graduations to Range 2 with coarse graduations with a load on the scale unless the scale is switched to a special function (like preTare, for example). For technical reasons, it is only possible to switch from coarse Range 2 to fine Range 1 with no load on the scale. In this case too, no special function may be activated.

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.

Model 675

GB 25

– 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 weight of the additional load. 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 triangle with the exclamation mark indicates that this frozen display is an additional facility which is not subject to calibration. – 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 once 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 28. – To return to normal weighing mode, press the FUNC key. – To switch off the scale, press the Start key again.

Model 675

GB 27

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. – 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. 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.

28

– To switch off the scale, press the Start key again. Tip: Note weight 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.

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. … 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 batteries. If this measure is equally unsuccessful, inform the Service department. … the weighing range won’t switch? – Take the load off the scale if necessary. – Ensure that no special function is active.

9. Servicing/recalibration Have the scale recalibrated by authorised persons in accordance with national legal requirements. The year of initial calibration can be found behind the CE symbol on the rating plate above the number of the appointed office, 0109 (Hessen Weights & Measures Office). Recalibration is essential if one or more security marks are damaged or the calibration counter does not match the number on the applicable calibration counter mark (cf. page 24). We recommend having your scale serviced by your local service agent before having it recalibrated. seca Customer Service will be pleased to give you further assistance.
