1. INTRODUCTION
General Information
Thank you for purchasing the scale. Please read all operating instructions carefully before
use and keep the following points in mind:
Avoid lengthy exposure to extreme heat or cold, your scale works best when operated
at normal room temperature. Always allow the scale to acclimate to a normal room
temperature before use
Allow sufficient warm up time. Turn the scale on and wait for a few minutes if possible,
to give the internal components a chance to stabilize before weighing.
These electronic scales are precision instruments. Do not operate near an in-use cell
phone, radio, computer or other electronic device. These devices emit RF and can
cause unstable scale readings. If your scale ever performs poorly, try moving the scale
to a different room or location.
Avoid using in condition of heavy vibration and airflow.
Read the weight reading in short time after loading. The output signature of load cell
and A/D may be little influenced after weighing for a long time.

4. OPERATIONS
4.1Correct 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

when no weight on the platform or being switched off.
4.4 Weighing with preset tare values
Press the ON/OFF/ZERO with no load on the scale.
Press and hold the TARE/PRESET key until the NET indicator flashes and “Pr.Tare”
shows in the display.
Input the tare weight using the arrow keys (already known the weight of the wheelchair).
After inputting the tare weight, press the TARE/PRESET key to confirm. The NET
indicator will be lit on the display.
Note: Tare weight must be greater than zero and less than the scale’s maximum capacity.
Put the patient and the additional weight (e.g. in the wheelchair) to be weighed onto the
scale platform. The net weight will be displayed.
To exit preset tare mode, remove all weight from the scale. The display will show a
negative weight. Press the TARE/PRESET key to return the display to zero, eliminating
the weight of the container.
Note: The indicator can only save one tare weight. Entering a new tare weight will
automatically replace the old one.
4.5 HOLD function
The Hold function is being used if you like to hold the results at the display after the
weight/load has been removed from the scale. Use this button to take care of the patient
first and then note the weight.
Press HOLD/SETUP key while scale is under load.
“HOLD” is being displayed at the screen.
The weight remains saved in the display after unloading the scale.
For deactivation of the Hold function press again the HOLD/SETUP key.
4.6 BMI function
The Body Mass Index is the ratio between height and weight squared. The BMI is accepted
world wide –also by WHO (World Health Organization) - helping to evaluate the state of
nutrition and with that value also the state of health of a person. The result is a tolerance
value.
Start the scale by entering the ON/OFF/ZERO Button. The scale is automatically being
set to zero.
Step on the scale or helping the patient to get into the wheelchair and on the platform.
Wait until the weight is being displayed in a stable condition and ´ ’ appears on
the screen.
