1.0 Introduction
The Rice Lake Digital Wheelchair Scale from Rice Lake is a user-friendly, quality scale, designed for safe
weighing of the handicapped and mobility challenged individuals. Movement compensation technology ensures
sound, accurate weighments. The scale has roll on ramp access and comes in four different configurations:
• Single ramp wheelchair scale
• Single ramp platform wheelchair scale • Dual ramp wheelchair scale • Dual ramp platform wheelchair scale
The scale has a non-skid rigid platform and two rear heavy duty wheels for easy maneuverability.
Figure 1-1. Digital Wheelchair Scale (single ramp and dual ramp models shown)
The scale is set up to use motion sensing technology, to determine actual weight of a moving patient. The weight
can be displayed in either pounds or kilograms and you can enter a tare weight. The scale operation section on
page 8 of this manual explains the scale operation and how to obtain a tare weight.
The wheelchair scale has a unique folding feature that enables easy transportation and simplifies assembly,
avoiding the need for field wiring and recalibration. All that is required is to open the packaging and unfold the
scale.
Place a known weight on each corner of the scale. The display should illuminate that known weight. If it does
not, trimming will be required. See “Trimming Procedure” on page 28.

2.0 Scale Assembly
2.1 Unpacking Your Scale
Place the unopened box in an open area that has ample room for unpacking the scale.
Recommended tools needed to set up your scale include:
• Scissors or a box cutter
Using scissors or a box cutter, cut the strapping bands that secure the box together. Immediately after opening the
box, visually inspect your scale to ensure all parts are included and undamaged.
Parts contained in the shipping box include:
• The scale
• This manual
• Small box containing AC adaptor, RS-232 cable, and scale feet
Figure 2-1. Box Contents Including the Scale Surrounded by Styrofoam Packing Material
2.2 Repacking
If the Digital Wheelchair Scale must be returned for modification, calibration or repair, it must be properly
packed with sufficient packing materials. Whenever possible, use the original carton when shipping the scale
back.
Damage caused by improper packaging is not covered by the warranty.

2.3 Setting Up Your Scale
Use the following steps to set up the Digital Wheelchair Scale.
1. Locate the users manual from inside the box and set aside as it will provide instructions on the proper
scale removal and set up.
2. Using two people, remove the scale out of the packaging material that it came in by lifting the scale out
of the box by the scale base as shown in Figure 2-2.
DO NOT lift the scale out of the box by its handle as this can cause the hinges to break or affect the scale
operation.
.
Figure 2-2. Lift the Scale From the Box
3. Move the scale into the area where the weighing process will occur. It’s recommended to place the scale
on a hard, level surface for the most accurate weighments. Thin carpeting is fine but not recommended.
4. Stand the scale on its side as shown in Figure 2-3, so that the plastic packaging material can be removed.

2.4 Attaching the Feet to the Scale
The Digital Wheelchair Scale comes with four feet that must be attached to the scale base for proper operation.
The four feet are located in the parts box in the original shipping box. Use the following steps to attach the feet to
the scale.
1. Screw the four round feet clockwise into the scale base as shown in Figure 2-4.
Figure 2-4. Screw Feet Into the Scale Platform
2. There must be adequate clearance between the scale base and the floor so screw each foot out
counterclockwise two full turns. This will ensure that there is enough clearance between the scale base
and the floor.
3. Gently set the scale base down to the floor. There should be minimal clearance between the scale base
and the floor without having the scale base actually touching the floor. Figure 2-5 shows the width of a
finger being slid under the scale base and the floor.
By not having clearance around the scale base will create inaccurate weighments
Figure 2-5. Have a Minimal Amount of Clearance Between the Scale Base and the Floor
4. It’s also important to make sure that the scale is completely level. Gently press down on all corners of the
scale base to ensure that there are no high spots or rocking of the scale base.
An un-level base will produce inaccurate weight readings.

5. Loosen the handles (shown in Figure 2-6) and set upright as shown in Figure 2-7.

Figure 2-7. Set Scale Handles Upright
6. Tighten the two hinges on the Digital Wheelchair Scale by rotating the two handles. This will secure the
handrail mounted indicator.

2.5 Hooking up the AC Power Connections
The Digital Wheelchair Scale has a 120 VAC adaptor or 230 VAC adaptor to use when power is readily available.
The AC power adaptor plugs into the back of the indicator as shown in Figure 2-8.
.
Figure 2-8. LED Light Location
The AC adaptor, when not in use, plugs into the back housing of the indicator for storage. Figure 2-8 shows that
location.
The Digital Wheelchair Scale is capable of running its internal sealed lead-acid rechargeable battery if no
additional power source is available. Battery life is approximately 75 hours. If the LO Bat indicator is showing on
the display, recharge the battery or connect the scale to an AC power source as soon as possible for accurate
weighing.
Battery Charging
When the AC adaptor is connected to a power source, the rechargeable battery goes into recharge mode.
To maintain battery longevity we recommend you charge it on a regular basis rather than waiting until it is
fully discharged.
The LED indicator light on the back of the scale housing will illuminate red during the charging period, and
change over to green when the battery becomes fully charged.
