1. INTRODUCTION

General Information

• The 244293 scale is a Digital Handrail Scale with Body Mass Index (BMI) readout.

• It is designed two handles and two wheels, offering the flexibility to move around.

• It is an accurate electronic device with advanced design and stable performance. Do

not operate near cell phones, radios, computers or other electronic devices that emit
radio frequencies that may cause unstable readings.

• It is designed to measure the weight of a person and compute the BMI index once the
known height of a person is entered via the Indicator

lead wire (the lead wire is pre strung inside the column). Insert the column into the socket
on platform and attach using provides screws.(P4)

5. Insert the handrail connector onto the handrails, insert the handrails into the socket on
platform. Have the three poles vertical with each other, then attach the handrails
connector by using provided screws.(P5)

6. Carefully place the scale on its side, and firmly attach the handrails to the base using 2
large cap screws.(P6)

4. OPERATIONS

4.1 Weighing

 Press the start key ON/OFF/ZERO to enter the normal operating mode of the scale

without any weight 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.

 A person can now mount the scale. Ensure that he/she is not moving.

 After the weight is displayed and the symbol ` ´ appears the utmost weight has

been achieved.

 To turn off the scale press ON/OFF/ZERO for minimum 3 seconds.

4.2 How to change the unit of measure

 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 without any weight 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 weight on the platform, enter the TARE/PRESET button again to exit tare

mode.

 The tare value is likewise erased by the scale until pressing the TARE/PRESET button

when there is no weight on the platform or unit is switched off.

4.4 Weighing with preset tare values

 Press the ON/OFF/ZERO without any weight on the scale.

 Press and hold the TARE/PRESET key until the NET indicator flashes and “

Pr.Tare

” is

displayed.

 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 the HOLD/SETUP key again.

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 help the patient to get into the wheelchair and on the platform.
 Wait until the weight is be displayed in a stable condition and appears on the

screen.

 Press the BMI key shortly.
 The scale starts automatically with the last input. Use the arrow buttons

244293

. 9.

to enter the height of the patient, and confirm the height with the enter button

 The BMI will then be displayed on the indicator.
 To correct the given height press the BMI button once again and the display will return to

the height mode.

 To get back into normal weighing mode and leave the BMI mode, press the TARE

button.

4.7 Connecting additional devices

Connection of printer, PC or remote-display will be done with serial ports or USB port. For

connection of additional devices contact Global Industrial for further instructions.

4.8 Print out a record

The scales must be at standstill. The standstill status symbol must appear at the

screen.

Press the PRINT key to send the data to the serial interface.

Note: Printing is not possible if the net weight is 0. The print function only produces one
print-out. A repeated weighing process is required to print out another copy.
