4. OPERATIONS
4.1 Correct Weighing
Press the start key
ON/OFF/ZERO
to enter the normal operating mode of the scale with
no load on the platform. An automatic function test will be performed as well as the zero
setting of the scale. When `0.0´ appears, it means you are in the weighing mode.
Additionally the display shows the symbol `
´ to confirm stability of the zero setting.
The scale is now ready to be used.
Place the patient on the scale and ensure that he is not moving.
After the weight is being displayed and the symbol `
´ appears the utmost
accuracy has been achieved.
To turn off the scale press
ON/OFF/ZERO
for a period of minimum 3 seconds.
4.2 How to change the unit
The scale offers the possibility to select between the weighing mode kg and lb.
To change into another mode, press the
UNIT
key. Please check weighing mode after
switching on to get proper result.
4.3 Tare function
The tare function allows ignoring a fixed weight (e.g. wheelchair) that will be deducted after
each weighing procedure.
Proceed as follows:
Press the
ON/OFF/ZERO
with no load on the scale.
Place the additional weight of the object(s), which needs to be ignored, on the scale and
store the result by pressing the
TARE/PRESET
key.
The display is being reset to zero. The scale is now in NET weighing mode which is also
indicated on the display.
Remove the objects from the platform. The ignored weight is being displayed with a
minus.
Place the Patient and the additional weight (e.g. in the wheelchair) on the scale.
The scale determines the weight of the patient without the additional weight. You may
now use the scale for as many weighing procedures and the stored value will always be
deducted as long as the scale is not turned off.
When there is no any weight on the platform, enter the
TARE/PRESET
button again to
get of the tare mode.
The tare value is likewise erased by the scale until pressing the
TARE/PRESET
button
