"ON" switch to momentarily reset the readout's internal
timer. To turn the scale "off" before the automatic timer
does, press and hold the scale's "ON" pushbutton for a
few seconds.
In the case of the model 5102 physician's office scale,
the readout is left powered-on
at all times, and will
display "0.0" when the scale is empty. The model 6102
runs continuously on AC power, but because it employs
an internal back-up battery for power outages, will time
out after two (2) minutes during power outages.

ZEROING
It is a good technique to always turn the scale
on "empty" to verify the proper zero value of the scale.
The scale will then automatically establish a new "zero"
value,
in the case of the model 5002 stand-on scale,
and the model 6502 chair scale, it is possible to stand
or sit on the scale first and then tum İt on.
In this
instance the scale knows that it cannot establish "zero"
because
a patient is already
present,
so
it simply
displays the weight using the previous "Zero" value.
This cannot be done with the models 6002 and 6702
wheelchair scales or model 6202 ramp scale since the
ramps
could
be either in the up or down
position.
These scales must be set to "zero" first by turning it on
empty and allowing the automatic zeroing feature to
operate.
This can be done with ramps up or down.
If
the patient gets on the scale before turning it on, the
patient will receive the prompt "OFF
SCALE
PLEASE
=". Simply remove the patient from the scale, and wait
for it to automatically go to zero (scale displays "0.0"
and beeps twice); or press the "ZERO" pushbutton, wait
for the two beeps, and continue weighing.
Operating tip:
By use of the "ZERO" pushbutton it is
possible to weigh babies and small children who would
not otherwise be able to stand on the weighing deck,
Have the nurse or mother stand
on the scale
and
remain
stationary
while
the
"ZERO"
pushbutton
is
pressed. Immediately after the scale obtains "zero" (two
beeps
and displays "0.0"), have the same
nurse or
mother hold the baby or small child while on the scale.
The weight of the nurse or mother will automatically be
subtracted from the total and the true weight of the baby
will be displayed.
While not as accurate as using a
pediatric
scale,
a
reasonably
close
weight
will
be
obtained.
A
minimum
weight
of five (5)
pounds
is
required
on
early versions
of these
scales;
newer
models will weigh a minimum of one (1) pound.
The same type of zeroing technique can be used when
placing
a
chair
on
the
deck
of
the
models
6002/6102/6702 wheelchair scales.
Place the chair on
the deck and press the "ZERO" pushbutton.
The scale
will beep two (2) times, then display "0.0".
The weight
of the chair is now automatically subtracted from the
total, and a patient sitting in the chair will be weighed
correctly.
To continue with normal
patient weighing
after
employing
either
technique,
simply
press
the
"ZERO" pushbutton with the weighing deck empty.
3.30
OBTAINING WEIGHT
Once
the patient stands
on the scale
it will
display a series of dashes indicating it is computing the
weight.
During this time the patient should remain
motionless.
If the scale is equipped with a handrail the
patient may grasp it to help in remaining stationary. The
black steering handle on the top of the readout should
not be touched during the weighing process.
Once the weight is obtained the scale will beep three
times and display the patients weight.
3.31
WEIGHT UNITS
The weight may be displayed in either pounds
{LB) or kilograms (KG) by selecting the appropriate front
panel pushbutton.
An annunciator on the front panel of
the readout will illuminate fo show the currently selected
units.
The weight units may be selected at any time
during the weighing process.
The scale will remember the selected units when it is
turned off.
Upon
powering it up it will automatically
default to this previously selected unit.
By use of the set-up feature (see section 3.70) the scale
can be programmed to display in either pounds only or
kilograms only. It can also be programmed to display in
resolutions other than
0.1
kilogram/pound
{again see
section 3.70).
3.32
REWEIGH
The
"RE
WEIGH"
pushbutton
provides
a
convenient method of re-obtaining the patient weight if
