GENERAL
The control panel of the SCALE-TRONIX® model
4802 PEDIATRIC SCALE is designed for operator
convenience.
A brief outline of the controls and
features is provided below:
3.01
ON / (OFF) / ZERO
This front panel pushbutton serves to turn the scale
"on" from the "off" position by pressing it briefly. At
the same time, briefly pressing this pushbutton
causes the scale to obtain "zero" by subtracting out
the weight of the cradle and any miscellaneous items
(liners, blankets, etc.) placed on it.
pressing this pushbutton also serves to reset the
internal automatic shut-off time when the scale is
operating from its internal battery.
To turn the scale "off", whether operating from AC line
or internal battery, press and hold the "ON / (OFF) /
ZERO" pushbutton for several seconds until the
display and annunciators turn off.
3.02
KILOS / POUNDS
This pushbutton is used to display the weight in the
appropriate choice of units. Pressing this pushbutton
switches the display from kilograms to pound/ounces
and back again.
annunciator(s) will illuminate to show the selected
units. The scale's internal memory will store the
selected weight unit and automatically operate the
scale in this mode on power-up.
If the scale has been set-up to use some of the other
units, such as pounds or ounces (see section 2.40), it
will also display them in succession. If the scale has
been set-up to display in a single unit only (example:
kilograms only) the "KILOS/POUNDS" pushbutton
will be inoperative. Some hospitals have a specific
requirement to have their scales weigh in kilograms
ONLY (or pounds in some cases). In this case, the
switch will not be active and should be covered up.
3.03
REWEIGH
The "REWEIGH" pushbutton causes the scale to
update the weighing cycle and lock-in a new weight
reading. This allows the patient to be weighed again
without removal from the cradle. If you suspect the

weight reading might be in error (perhaps you were
touching the infant at the time of the weighing),
pressing "REWEIGH" will cause a new weighing
cycle to start.
3.04
RECALL PRIOR WEIGHT
This pushbutton displays the weight that has been
stored in the scale's memory from the last patient. It
is a useful feature that allows the operator to
immediately return the infant to the bassinet or
incubator, without having to pause to chart the
patient's weight.
The last patient's weight can be displayed by simply
pressing
pushbutton and observing the display. The "PRIOR
WEIGHT" annunciator on the front panel will flash
simultaneously. The weight reading will display as
long as the "RECALL PRIOR WEIGHT" pushbutton
is held. The weight reading can then be charted or
confirmed.
The patient's weight is stored into the scale's prior
weight memory when that patient is removed from the
scale's cradle, or if the scale is switched "off" with the
weight being displayed. Use of the "RECALL PRIOR
WEIGHT" feature allows comparisons to be made
between "old" and "new" weights. This data can then
be used to calculate infant feeding amounts.
3.10
BATTERY OPERATION
The scale's electronics have been improved over the
years and power consumption greatly reduced. This
has allowed us to eliminate the need of the
rechargeable batteries.
The scale is now equipped with six (6) size "D"
disposable alkaline cells (DURACELL brand). These
batteries provide several thousand weighings; often
more than a year of use. We recommend the use of
DURACELL brand alkaline batteries ONLY. Use of
any other brand will affect performance and will void
the warranty. See section 3.90 for details on how to
identify genuine DURACELL batteries. The scale will
automatically shut-off after 90 seconds of non-use.
The automatic shut-off time adjustable from 15
seconds to 3 minutes (see section 2.40). The scale
may also be shut-off manually by pressing and
holding the "ON / (OFF) / ZERO" pushbutton for
