The SCALE-TRONIX® model 4802 PEDIATRIC
SCALE is usually shipped with the scale and cradle in
a single carton. If the oversized cradle option was
ordered, this cradle will be shipped in a separate
carton.
Please save the carton(s) and shipping
materials for possible future use if the scale is ever to
be returned to the factory for service or upgrades.
Carefully inspect the carton(s) for shipping damage
before unpacking. Contact the shipping company
and SCALE-TRONIX® immediately if shipping
damage is found. All claims must immediately be
made directly with SCALE-TRONIX®.

ASSEMBLY INSTRUCTIONS

(Refer to illustration 1)
The SCALE-TRONIX® model 4802 PEDIATRIC
SCALE is fully assembled at the factory and tested.
The scale is shipped with the weighing cradle
removed.
This insures protection of the delicate
weighing transducers.
Carefully remove the acrylic weighing cradle from the
shipping carton. Remove the scale from the carton
and place it on a counter top or stable cart. Position
the cradle over the scale so the four metal mounting
posts line up with the holes in the top of the scale.
Note the length gauge and rotate the cradle if
necessary so the length gauge is "right reading".
Apply a gentle downward pressure to "plug-in" all four
posts so the cradle rests firmly on the scale.

CHECK-OUT

1.
Turn the scale on by briefly pressing the
"ON / (OFF) / ZERO" pushbutton on the
front panel. A single "beep" will be heard.
The scale should display "888888" and
illuminate
the
"OUNCES", "PRIOR WEIGHT" and "LOW
BATTERY" annunciators as a test of their
operation.
Observe these digits and
annunciators to insure they light. The scale
will then briefly display its model number,
"4802".
During this short time period the
scale also performs some internal checks of
its operation.
2. After a short period of settling, the scale will
then automatically establish its "zero" value,

removing the weight of the cradle and any
miscellaneous items left in the cradle. The
display will show "0.000 KILOS" or "0

previous mode. A series of two beeps will be
heard signaling the setting of zero.
3. Place an object to be weighed on the cradle.
A one or two liter bag of IV solution will do. A
series of moving dashes ("-----") will be noted
on the display indicating motion of the cradle.

be functional.
5. Place an additional small object on the
cradle. Press the 'REWEIGH" pushbutton

"DIAPER WEIGHING CAPABILITY perform
steps 6, 7, and 8; otherwise skip to step 9.
Obtain a stack of about 25 standard sized (2"
x 3-1/2") business cards to use as test
weights. Insure that the scale is properly
placed on a steady surface and that they are
not any fans or overhead vents blowing on
the cradle (with measurements as sensitive
as these, small breezes can affect the weight
readings!) Remove all items from the cradle
and press the "ON / (OFF) / ZERO"
pushbutton on the front panel to obtain a zero
reading. If necessary, set the weight mode to
