INTRODUCTION
The Detecto 450 Series Mechanical Baby Scale is ideal for use in health clinics and medical
practices for height and weight measurement of pediatric patients. The scale is durable, having
a sturdy enameled steel scale base, a built-in measuring tape (up to 21 in / 53 cm) to allow the
healthcare professional to measure both weight and height simultaneously, and an easy-to-
clean polystyrene tray that cradles babies securely.
This manual is provided to guide you through the assembly and operation of your scale.
Please read it thoroughly before attempting to assemble or operate your scale and keep it
available for future reference.
This manual is for use with the following Mechanical Baby Scale models:

Wrench (included)
1. Set the scale base on a table or other assembly area free from traffic and obstructions.
2. Remove the cable tie that secures the draft rod during transit (shown in Figure 1).
Figure 1. - Remove cable tie securing draft rod in column
3. Insert the column onto the scale base (shown in Figure 2), ensuring that the DETECTO
logo on the weight beam faces the scale base.

4. Using a Phillips screwdriver, install the eight screws and washers to secure the column to
the scale base as shown in Figure 3.

5. Lay the scale on a table. Remove and discard the shipping tie-wrap wires on the underside
of the scale base as shown in Figure 4.

6. Insert the wrench (included) into the small hole in front of the draft rod and pull the draft rod
hook with the wrench to connect it to the long lever as shown in Figure 5. The draft rod is
located inside the scale column. Once the column is attached to the scale base, the draft
rod must be attached to the long lever.
Figure 5. - Connect draft rod hook to the long lever
7. Push the long lever forward and hook the draft rod’s hook onto the long lever pivot.
IMPORTANT! During shipping, a plug is installed to ensure that the shelf lever
assembly stays aligned. However, the linkage may still come out of alignment.
Remove the plug and then visually ensure that the shelf lever assembly linkage is
centered and properly aligned. The linkage must be free-floating for the scale to
weigh properly. If the scale is slightly tipped to one side, the linkage can be seen by
looking up underneath the weigh beam headpiece.

BALANCING THE SCALE
After assembly, the scale must be balanced before using it.
1. Ensure the scale is sitting on a level surface, and slide both the small and large poise to
zero (far-left position on the weigh beam).
2. Gently hold the beam pointer with your finger so it is centered within the trig loop area.
Release the beam pointer and let it rise freely up or down.
3. If the beam pointer doesn’t remain centered, turn the balance screw (shown in Figure 8) to
the right or left using a flathead screwdriver until the beam pointer remains centered within
the trig loop.

OPERATING THE SCALE
The following steps will guide you through the operation of your 450 Series, Weigh Beam
Neonatal Scale. Refer to Figure 9 below when performing the steps.
1. Move both poise to the Zero position. Be sure the Beam Pointer is in the center of the
opening in the Trig Loop.
2. Slide the Large Poise to the approximate weight. For example, if the patient weighs
approximately 20 pounds, slide the Large Poise to 10 pounds.
3. Place the patient on the scale, and then slide the Small Poise to 5 pounds.
4. Continue sliding the Small Poise until the Beam Pointer is centered in the Trig Loop
opening.
5. Read the Small Poise at the pointer and add to the 10 pounds from the Large Poise. For
example, if the pointer is at 8 pounds, the patient weighs 18 pounds.
Figure 9 - View showing the procedure for weighing operation.
CAUTION!
Do not leave the baby unattended in the baby tray.
Failure to maintain continual control of the baby can
result in serious injuries should the baby fall from the
baby tray.
