1.0 Introduction
The Rice Lake Mechanical Physician Scale is ideal for use in health clinics and doctors’ practices for height and
weight measurement. The scale comes in a variety of configurations. Those configurations include:
• RL-MPS: Lb/kg model with height rod and rear wheels
• RL-MPS-10: Lb only model with height rod and rear wheels
• RL-MPS-20: Lb/kg model
The scale is durable, having a sturdy enameled steel body, removable slip resistant plastic cover and some
models come with a retractable aluminum height rod and rear wheels. These installation and operating
instructions will guide the user through basic instructions on pillar assembly, wheel installation, pillar height rod
installation, and the zero adjustment of the scale.

2.0 Installation Instructions
You will receive your Mechanical Physician Scale partially assembled. Those items that need additional
assembly are:
• Pillar assembly
• Steelyard rod connection
• Height rod installation (for models having a height rod)
• Wheel installation (for models having wheels)
Remove all components from the shipping box (shown in Figure 2-1) and lay out in a convenient place.
Figure 2-1. Box Contents
2.1 Pillar Installation
Prior to assembly, you’ll need the following tools to finish assembling the Mechanical Physician Scale.
• Phillips head screwdriver
• Wrench (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.
2. Remove the twisty ties off the scale base as shown on the left hand side of Figure 2-2. Remove the cable
tie that holds the steelyard rod from shifting during transit (shown on right side of Figure 2-2).

3. Insert the pillar into the scale base assembly ensuring that the RLWS logo located on the weight beam
faces the scale base.

2.2 Steelyard Rod Connection
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 on a table as shown in Figure 2-5.
Figure 2-5. Lay Scale on Table to Access Bottom of Scale
2. There are tie wrap wires that prevent the underside of the scale carriage from shifting during shipping.
Remove and discard the wires on the levers as shown in Figure 2-5.
3. Insert the wrench (included) to the small hole in front of the steelyard rod, and pull the hook of the
steelyard rod with the hook of the wrench to connect it to the scale base as shown in Figure 2-6.

4. Push the long lever frontward, then hook the bearing of the steelyard rod on the pivot of the long lever.
NOTE: Visually ensure that the force lever assembly linkage is centered and properly aligned. Occasionally during
shipping, the alignment will become skewed however a plug is installed to ensure that the linkage stays aligned. The
linkage must be free floating in order for the scale to weigh properly. The linkage can be seen by looking up underneath

2. Use the enclosed wrench to tighten the two hex-head screws, but ensure not to over tighten.
3. To raise or lower the height rod, press the red button at the top of the height rod and raise up or down.
