1.0 Introduction
The Rice Lake Digital Wheelchair Scale 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 folding wheelchair scale
• Single ramp platform wheelchair scale
• Dual ramp folding 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 pounds or kilograms and you can enter a tare weigh t . Section 3.0 on page 6 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
d wiring and recalibration. All that is required is to open the packaging and unfold the scale.

2.0 Scale Assembly
2.1 Unpacking Your Scale
Place the unopened box in an open area that has ample room for unpa cking 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 the scale and components to ensure all parts are included an d undamaged.
Parts contained in the shipping box include:
•Scale
• Box containing six AA batteries and four feet
2.2 Repacking
If the Rice Lake Digital Wheelchair Scale must be returned or moved, it must be properly packed with sufficient packing
materials. When possible, use the original carton and packing material.
Damage caused by improper packaging is not covered by the warranty.
2.3 Setting Up Your Scale
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 acceptable, but not recommended.
Rice Lake recommends using two people for lifting the scale and to use proper lifting techniques to prevent
injury.
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.
1. Using two people, lift the scale out of the box by the base.
2. Stand the scale on edge to remove the packing material.

Batteries must be removed from the unit prior to long periods of disuse or long term storage.
If an external power supply or USB power supply is connected, the battery flag on the display is turned off.
When using battery or USB power supply, the back light power is deducted to 60%.
2.5 AC Power Connections
Use the optional 120 VAC or 230 VAC adapter when power is available. Rice Lake Weighing Systems offers optional AC
adapters that plug into the back of the indicator as shown in Figure 2-5.

3.0 Scale Operation
The Rice Lake Digital Wheelchair Scale display has various front panel keys as shown in Figure 3-1.
Figure 3-1. Front Panel Display Keys
Key Descriptions
Table 3-1 describes each of the key functions.
Item No Name Function
1 BMI Enables the user to access the BMI (Body Mass Index) function. This key only works if there is a locked weight shown on
the display and the BMI function is turned on in the configuration mode.
2 TARE Used to subtract the weight off the scale, example: oxygen tank, other equipment.
3 CLEAR Allows the user to return to normal weighing when the BMI value is being displayed.
While in BMI mode, the height display causes the value to return to the default of 190.0 cm, 5 ft, 7.5 in.
4 Print
LB/KG
5 Zero Clears the weight off the scale and returns it to zero after three seconds.
6 Hold
Release
7 On/Off Switches the scale on or off.
8 ENTER Used to accept height in BMI mode.
9 Up/Down Arrows Used to adjust height input (0.5''/0.5 cm) while in BMI mode.
The keys on the front panel display are very sensitive so only a gentle pushing motion is required to obtain
results.
The scales have the capability of performing different operations beyond just calculating weight. The various operating
instructions are described below.
Print — A long key press will send data out from the RS-232 port.
LB/KG — A short key press allows the user to toggle between kilograms and pounds providing that it’s enabled in config-
uration mode.
There is no toggling while in the BMI mode.
It works only if the current weight is stable and zero up to 2% of full weight.
Hold & Release — The first press holds the most current weight value shown on the display.
A second press releases the weight value shown.
This key is not active while in BMI mode.
Accepts the value of the parameter last entered and moves to the next stage.

RL350-10 Digital Wheelchair Scale
5.0 RS-232 Communication
The scale comes with an RS-232 port that enables weight data to be transmitted to other equipment, such as a computer or
printer. The RS-232 cable with DB-9 connector (PN 100719) is available from Rice Lake Weighing Systems.
page 17 shows where the RS-232 connection is.
The RS-232 parameters are 9600 baud (selectable in the programming mode), 8 data bits, 1 stop bit, no parity and no
handshaking.
There are three methods of communication:
• Pushbutton keypad print
• Escape protocol
• Maintenance protocol
5.1 Push-Button Keypad Print
With a stable, in-range weight, press and hold the LB/KG/Print key for at least three second s, or until the scale displays PRINT.
Note that if the scale does not beep after five seconds, then release the button as the weight was either in motion, or out of
range.
If displaying weight and not BMI, the scale will send out the following 21 character string:
xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>
Where:
xxxxxxxxx is the weight with decimal point and " - " sign, if negative uu is the unit (lb or kg).
mmmmm is the mode (gross or net)
Example:
60.1 KG= <PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>
Figure 5-3 on
In BMI mode (displaying the BMI value), the scale will send out the following data:
PATIENT WEIGHT 60.1 KG
PATIENT HEIGHT 170.0 CM
PATIENT BMI 20.8
Example in KG:
<PATIENT><SP><WEIGHT><SP>-60.1<SP>KG<SP><CR><LF>
<PATIENT><SP><HEIGHT><SP>-170.0<SP>CM<SP><CR><LF>
<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.8<SP><SP><SP><SP><CR><LF>
Example in LB:
<PATIENT><SP><WEIGHT><SP>132.4<SP>LB<SP><CR><LF>
<PATIENT><SP><HEIGHT><SP>-5-07.5<SP>FT<SP><CR><LF>
<PATIENT><SP><B><SP><M><SP><I><SP><SP><SP><20.4<SP><SP><SP><SP><CR><LF>
In case of under weight or over weight, the word Under or Over will be sent correspondingly.

RS-232 Communication
5.2 Communication Protocols
The Rice Lake Digital Wheelchair Scale has two communication protocols, escape and maintenance protocol.
5.2.1 Escape Protocol
An escape protocol is where the escape (0X1B or ASCII 27) is used to indicate that there is a command following. On the PC
side there must be a listener created by the vendor that will interpret this protocol. This listener must also take care of all the
issues regarding data integrity to make sure that the data that was sent and received is valid.
Two examples include:
• Scale initiated communication
• PC initiated communication
Table 5-1 is what can be sent across communications lines.

6.0 Troubleshooting and Maintenance
6.1 Maintenance
The following section provides instructions for maintaining and cleaning the Rice Lake line of scales.
Do not immerse the scale in cleaning or other liquid solutions.
Do not use Isopropyl alcohol or other solutions to clean the indicator display surface.
6.1.1 Basic Maintenance
Before using the scale and after periods of non-use, check the scale for proper operation and function. If the scale does not
operate correctly, contact a qualified service personnel.
Basic maintenance includes:
• Check the overall appearance of the entire scale for any obvious signs of damage.
• Inspect the condition of the AC adapter cord for cracking, fraying or broken/bent prongs.
• Using an adapter that has been used elsewhere may cause issues with the scale.
• Change batteries on a regular interval. Leaving in for lo
6.1.2 Cleaning
Proper care and cleaning is essential to ensure a long life of accurate and effective operation. Before beginning the cleaning
process, disconnect the scale from the AC power source.
• Clean all external surfaces with a clean, damp cloth or tissue.
• Mild soap and water solution may be used.
• Standing platform may be cleaned with Isopropyl alcohol
• Dry with a clean soft cloth.
