BASIC SYSTEM OPERATION
SETTING SYSTEM ZERO
Make sure the scale is free and clear of any obstructions and press and hold the
ZERO /
WEIGH
button. The displayed message will indicate
“
HOLD TO ZERO
” and count
down to zero.
Make sure that nothing is in contact with the scale while zeroing the system.
In a few seconds, the display will read “
WT = 0.0 Lb
”
(or
Kg
)
. This action also resets
previously stored weight, height, and BMI values to zero.
WEIGHING
Position the patient on the scale. The care-giver must be standing on the scale when
moving the wheelchair on or off the scale. Lock the patient’s wheelchair to prevent
movement. Press the
ZERO/WEIGH
button. The weight stable indicator
“
” flashes
on the display. When the weight is stable, the weight stable indicator remains solid. The
display will indicate the patient’s weight in either pounds or kilograms; example: “
WT =
123.5 Lb
”. The stable weight is auto stored in memory.
NOTE:
If patient will be using a cane for support on the scale, place cane on scale while
zeroing the system. This will ensure that the patient’s NET weight will be displayed. It is
recommended that the system be zeroed prior to each new patient.
CALCULATING BMI
Press to calculate BMI.
When the
BMI
button is pressed, the default starting value is set either to 65 in or to 165
cm; example: “
HT = 65 in
”. Use the
UP
or
DOWN
arrows to adjust the default height to
the value of the patient’s height.
NOTE:
To calculate the BMI, a patient’s stable weight needs be stored as indicated in
“
WEIGHING
” above, if no stable weight has not been stored “
NO WEIGHT DATA
”
will be displayed and the display will then go back to the weigh screen “
WT = 0.0 Lb
”.
Press
ENTER
to save height data and display BMI calculation. The BMI will be
displayed; example: “
BMI = 20.5
”.
CARE-GIVER MUST ASSIST WHEELCHAIR-BOUND PATIENTS.
DO NOT LEAVE PATIENT UNATTENDED ON THE SCALE PLATFORM.
