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.
This manual can be viewed and downloaded from the Rice Lake Weighing Systems
web site at www.ricelake.com/health. Technical information on these products and
other medical products are available on the Rice Lake Weighing Systems web site.

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.
Note

Wheelchair Scale Technical and Operating Instructions - Scale Assembly 3
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.

3.0 Scale Operation
The display has various front panel keys. They are shown below and their function is described in 3-1.
Figure 3-1. Front Panel Display Keys
The keys on the front panel display are very sensitive so only a gentle pushing motion is required to
obtain results.
The scale has the capability of performing different operations beyond just calculating weight. The various
operating instructions are described below.
3.1 Weighing a Patient
Use the following steps to weigh a person.
1. Press the On-Off/Zero key to turn on the scale and 0.0 will appear on the display.
2. Wheel the patient onto the scale. The display shows WEIGH, then the patient’s weight, and beeps to
indicate the end of the weighing process.
3. To ensure an accurate weighing, press the REWEIGH key.
4. To change the display from Kg to Lb and vice-versa, press the Kg-Lb key.
5. The scale is set to lock in the weight when the weighing process is complete. The weight will remain on
the display even after the patient exits off the scale. To clear the weight, press the On-Off/Zero key.
6. To turn off the scale, press and hold the On-Off/Zero key until OFF appears on the display.
Key Name Function
ON-OFF/ZERO ON-OFF - Switches the scale on or off.

Wheelchair Scale Technical and Operating Instructions - Scale Operation 9
3.2 Using the Body Mass Index (BMI) Function
Body mass index (BMI) is the relationship between weight and height associated with body fat and health risk. It
is a reliable indicator of body fatness for people and even though BMI does not measure body fat directly,
research has shown the BMI correlates to direct measures of body fat. BMI is an inexpensive and
easy-to-perform method of screening for weight categories that may lead to health problems for adults.
Calculating BMI is one of the best methods for population assessment of overweight and obesity. Because
calculation requires only height and weight, it is inexpensive and easy to use for clinicians and for the general
public. The calculation is based on the following formulas:
Calculate BMI by dividing weight in pounds (lbs) by height in inches (in) squared and multiplying by a
conversion factor of 703.
Example: weight = 150 lbs, height = 5’5 (65")
Calculation: [150 ÷(65)2] x 703 = 24.96
The standard weight status categories associated with BMI ranges for adults are shown in the following table.
The following examples show weight ranges, the corresponding BMI ranges and the weight status categories for
a sample height.
Use the following steps in determining the BMI.
1. To use the BMI function, weigh the patient as described under Weighing and then press the BMI key. If
weighing in Lbs, the default height of (5 feet) appears on the display. Use the up or down arrows to
increase the feet height by one foot increments). Press the BMI key again to display inches (default is 7.0
inches) Again, use the up or down arrows to increase or decrease the inches height by 0.5" increments.
Press the BMI key again to accept the inches value. The final height value will be displayed ie: 5-07.5 =
5’ 7.5".
2. If you are weighing in Kgs, the default will be 170.0 cm. Use the up or down arrows to increase or
decrease by 0.5 cm increments.
3. To see the patient’s calculated BMI, press the BMI key again. The BMI appears.
4. To cancel the BMI display, press the BMI key.
BMI Weight Status
Below 18.5 Underweight
18.5 - 24.9 Normal
25.0 - 29.9 Overweight
30.0 and Above Obese
Table 3-2. Standard Weight Status
Height Weight Range BMI Weight Status

125 lbs to 168 lbs 18.5 to 24.9 Normal
169 lbs to 202 lbs 25.0 to 29.9 Overweight
203 lbs or more 30 or higher Obese
Table 3-3. BMI Ranges and Weight Status Example

10 Wheelchair Scale Technical and Operating Instructions
3.3 Using the Tare Function
You can use the tare function for deducting an extra weight (such as a wheelchair, or medical equipment attached
to the patient) in a weighing operation.
To get the most accurate reading, always use the same equipment for pre-weighing (getting the tare
weight) which includes things like the wheelchair footrests, blankets, etc.
Determining a Tare
Use the following steps to use the tare function.
1. With the scale set to 0.0, place the extra load (wheelchair) on the scale. The display shows WEIGH and
then the weight of the wheelchair.
2. Press and hold the TARE key until TARE appears on the display. The display returns to 0.0 and TARE
appears on the left side of the display.
3. Remove the wheelchair from the scale. The weight of the wheelchair appears with a negative symbol to
the left of it.
4. Wheel the patient onto the scale. The display then shows the patient’s weight without the weight of the
wheelchair.
5. The weight of the wheelchair remains stored in memory, so you can continue to weigh patients who are
carrying the same tare weight. For example, when using the same wheelchair for weighing more than
one patient.
6. To cancel the tare weight, press and hold the TARE key until TARE disappears from the display and the
display returns back to 0.0. The tare weight is also cancelled when the scale is turned off.
Entering a Known Tare Manually
Use the following steps to enter a tare without placing that item on the scale. An example of this would be if
you’ve got a patient in a wheelchair and the wheelchair has a known weight (has been tagged) you can enter that
weight manually.
1. With the scale set to 0.0 Lbs (there must be no weight on the scale), press the TARE key. The display will
alternate between a value and the word TARE.
2. To change the value, press and hold the Kg/Lb key until the right most digit is equal to the first digit of the
value you want. Example: If you want 103.5, hold the key until the display is 0.1.
3. To advance to the next digit, press the Kg/Lb key twice quickly. The digit you changed will move left and
the right most digit will again be 0. Again, hold the Kg/Lb key until the right most digit is equal to the
next digit in the numbers you want.
4. Continue as in Step 3 until you are displaying the value you want, then press the TARE key.
5. You can now accurately weigh the patient.
6. To cancel the tare weight, press and hold the TARE key until TARE disappears from the display and the
display returns back to 0.0. The tare weight is also cancelled when the scale is turned off.
