The Rice Lake Mechanical Baby Scale provides precise weighing of babies and toddlers. The scale comes in two
configurations. Those configurations include:
• RL-MIS (Lb-oz & Kg) with measuring tape in inches and centimeters
• R
L-MIS-20 (Kg only) with measuring tape in centimeters
The scale is durable, having a sturdy enameled steel body and a wipe down, molded plastic weighing tray with
measuring ruler.

2.1 Pillar Installation
Prior to assembly, you’ll need the following tools to finish assembling the Rice Lake Mechanical Baby Scale.
• Phillips head screwdriver
• Multi-purpose tool (included)
The pillar comes separate from the scale base and must be attached prior to use. Use the following steps to attach
the
pillar to the scale base.
1. Set the scale base on a table or other convenient place with the
photo in Figure 2-1).
2. Remove twisty tie off of the scale base as shown on the left hand side
that holds the steelyard rod from shifting during transit (shown in right side of Figure 2-1).

The steelyard rod is located inside the scale pillar. Once the pillar is attached to the scale base, the steelyard rod
must be attached to the bottom of the scale.
1. Lay the scale pillar on a table so that the scale platform hangs over the edge of the table and allows you
to access
2. Insert the hook part of the multi-purpose tool (included and shown below) to the small hole in bottom
the steelyard rod, and pull the hook of the steelyard rod with the hook of the multi-purpose tool to
connect it to the scale base lever as shown in Figure 2-4 then push the scale base lever towards the pillar

The weighing platter comes separate from the scale base and must be attached for proper operation. To attach the
weigh platter to the scale base, use the following instructions.
1. Position the weigh platter on top of the scale platform with the inch/cm marks located next to
shown in Figure 3-2.
2. Line up the screw holes as shown in Figure 3-1.

4.0 Zero Adjustment

Poise weights
To ensure accurate weighments, a zero adjustment should be done to the scale upon arrival and setup. To perform
a zero adjustment, perform the following steps.
1. Ensure the scale is sitting upright on a level surface.
2. Make sure that the poise weights are pushed all the way to the left hand side (at zero) making sure that the
large poise is firmly seated in the notch and the small poise is firmly against the shoulder of the beam.
3. Check the eye loop area of the scale to ensure that the scale pointer is centered.
5.0 Weighing a Baby
To weigh a baby, place the baby on the weigh platter and slide the larger poise (on bottom) to the approximate
target weight. Next move the smaller poise on top until the weigh beam balances and the scale pointer is centered
within the eye loop area as shown in Figure 4-1.
Figure 4-1. Eye Loop Area and Zero Adjusting Screw Location (Lb and kg version shown)
4. If the scale is not balancing properly, then the small zero balance weight must be adjusted. Turn the zero
adjusting screw (shown in Figure 4-2) using the enclosed multi-purpose tool. Depending on the direction
the zero balance weight will move accordingly.

6.0 Troubleshooting
For the most accurate weight, always use the scale on a hard, level surface and weigh in the center of the platform
with the weight distributed as evenly as possible. If an error occurs or seems excessive, check the following:
Problem Possible Fix
Zero balance of beam The weigh beam must be balanced so the pointer comes to
center of the eye loop (shown in Figure 4-1) when both poise weights are set
at zero (see Figure 4-1 for poise weight location). Adjust the balance by
rning the zero adjusting screw at the left end of the weigh beam (see
tu
Figure 4-2).
Beam does not move freely Check if the beam pointer is touching the side of the ey
travel.
Visually ensure that the linkage is centered and pr
2-6). Occasionally during shipping, the alignment will become skewed. The
linkage must be free floating in order for the scale to weigh properly. The
linkage can be seen by looking up underneath the top weigh beam if the scale
is slightly tipped to one side.
Platform rocks excessively When you push down on any c
significant rocking. Ensure scale is setting on a level surface.
Beam does not move at all during a weighment This can be caused by the poise
person’s actual weight. Reset the weights to a lower weight. Also check to
see that the steelyard rod is properly connected and aligned.
