OPERATION OF SCALES
3.00
GENERAL
The
SCALE-TRONIX®
second
generation
scales described in this manual all operate in a similar
fashion.
The
scales
readout
utilizes
computer
controlled digital systems to provide such features as
pushbutton
zero,
motion
detection,
units conversion,
memory
for recalling
previous
weights,
printer
and
computer data output options, etc.
The portable scales are truly cordless.
Power cords
have
been
eliminated
where
possible
with
no
compromise
on
battery life - typically
in excess
of
10,000 weighings for most units.
The typical operating procedure is very simple:
1.
With scale empty, turn it on by pressing the
"ON" pushbutton - (ONE BEEP)
2.
Wait for automatic zero
- (TWO
BEEPS).
3.
Place patient on scale and wait for the true
weight fo be displayed
- (THREE BEEPS).
That is all there is to it - simple as 1,2,3!
The scale will
even shut itself off after 45 seconds of inactivity to
conserve batteries, but will allow successive weighing
of several patients.
The time delay before shutting off
is selectable
by
the
operator
through
the
"set-up"
programming
feature (see section 3.70) and can be
changed if desired.
The weight
can
be displayed
in either pounds
or
kilograms by pressing the appropriate pushbutton.
The
scale will "remember" the selected weight units and turn
on in these units.
By use of the "set-up" feature the
operator can program the scale to display only in a
particular unit,
If, after the weight
is displayed
(three
beeps),
you
suspect
that the weight
might
be erroneous
due
to
someone touching the scale or patient, simply press
"RE WEIGH"
and the scale will calculate the weight
again,
beep
three times,
and
re-display.
The
scale
indicates motion by a series of dashes during the time
that the computer is determining the weight.
It's no problem If the patient exits the scale and you
forgot the
weight!
Simply
press
the
"RE
CALL"
pushbutton.
The
scale will display
the
last weight
measured,
snd
indicate so by blinking the "PRIOR
WEIGHT" light for a few seconds.
Note:
Ifthe patient will be operating the scale to obtain
self-weights, be sure to instruct them not to continue
to press on the readouťs
pushbuttons while the
weighing
process
is taking place!
Press the "ON"
pushbutton once, remove fingers from the control panel,
and stand clear to wait for the accurate weight.
(On a
scale as sensitive as these, the force of continuing to
press on the contro! panel while being weighed will be
reflected as an error in the weight reading!)
On scales equipped with a handrail, the patient may
hold on to the handrail to provide additional support.
It
is not permissible, however, to hold or touch other parts
ofthe scale such as the readout, black steering handle,
etc.
(That is like leaning on the bathroom sink when
weighing
yourself
at home;
good
for the
ego,
but
clinically not acceptable! )
Get in the habit of using the audible beeps to assist you
in the simple and proper operation of the scales.
The
beeper can easily be disabled by means of the set-up
programming feature in those instances where its use
isn't desirable.

POWER ON
Press the "ON" pushbutton located in the upper
right-hand corner of the control panel to switch the scale
on. The scale will beep once and then show "888888"
with
all annunciators
lit as
a test of the
readout's
display,
then
display
the
scale's
model
number
(example: "50029.
During this time a number of self-
tests are performed by the readout's internal electronics.
if
no
other
actions
are
performed
the
scale
will
automatically
shut
off after about
45
seconds.
if
additional operating time is required, simply press the
5002, 5102, 5602, 6002, 6102, 6202, 6502, 6702
