1.0 Introduction and System Overview
Dual Ramp
Model (RL-350-2)
Single Ramp Model with
Wheel Stop (RL-350-1)
The Rice Lake Bariatric Wheelchair Scale is a heavy-duty scale that easily accommodates wheelchairs with its
large platform size and easy-access ramp in either a single ramp (RL-350-1) or dual ramp model (RL-350-2). It
provides exceptional performance in applications where typical wheelchair scales are not large enough to meet
the needs of the patient.
The Rice Lake Bariatric Wheelchair Scale is a fully electronic, l
(.86 m x .86 m), and has a capacity up to 1000 lbs (500 kg). The Rice Lake Bariatric Wheelchair uses four
corner-mounted, alloy steel shear beam load cells, with the cells recessed into the frame channels for protection.
The Rice Lake Bariatric Wheelchair Scale offers two integral handles and wheels for ease of portability.
Load cell cables are run through the main channels, and held down with replaceable cable ties near eac
eliminating the possibility of cable damage in portable applications.
The Rice Lake Bariatric Wheelchair Scale comes equipped with a anti-slip rubber surface on the scale platform
and a large 1" LCD indicator display and a 120 VAC or 230 VAC adaptor to use when power is readily available.
It is also capable of operating on the internal sealed lead-acid rechargeable battery when no power source is
available.

Figure 2-4. Unwrap the Cable from the Underside of the Scale
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.
NOTE: By not having clearance around the scale base will create inaccurate weighments.
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.
NOTE: An un-level base will produce innacurate weight readings.
2.5 Cable Connections
Ten feet of 4-wire cable to connect the scale to the weight indicator is supplied with each scale.
NOTE:The cable is pre-installed from the factory.
The cable must be routed to the indicator in a manner that will protect the cable from damage. Cabling should
exit the underside of the scale on the portable wheel side of the scale and not the ramp side(s). When planning
cable routing, leave a loose coil of excess cable under the scale to facilitate future lifting of the scale for servicing
or cleaning.

4.2 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 populatio
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 fac
tor of 703.
Example: weight = 150 lbs, height = 5’5 (65")
Calculation: [150
÷ (65)
] x 703 = 24.96

4.3 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.
NOTE: 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 on the scale. The display shows WEIGH and then the weight
of the load.
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 load from the scale. The weight of the load appears with a negative symbol to the left of it.
4. Ask the patient to step onto the scale with the load. The display then shows the patient’s weight without
the weight of the load.
5. The weight of the load 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. 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 TAR E key. The display will
alternate between a value and the word
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 TAR E 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. The tare
weight is also cancelled when the scale is turned off.

7.0 RS-232 Communications
The scale comes with an RS-232 port which 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
System.
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:
7.1 Pushbutton Keypad Print
With a stable, in-range weight, press and hold the Kg-Lb/Print key for at least three seconds, or until the scale
emits two quick beeps. 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.
xxxxxxxxx<SP>uu<SP>mmmmm<SP><CR><LF>
Where:
Examples:
Figure 3-4 on page 6 shows where the RS-232 connection is.
• Pushbutton keypad print
• Standard remote protocol
• Escape protocol
• If displaying weight and not BMI, the scale will send out the following 21 character string:
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)
-10 Lb net = <SP><SP><SP><SP>-10.0<SP>lb<SP><SP>Net<SP><SP><SP><CR><LF>
10 Lb gross = <SP><SP><SP><SP><SP>-10.0<SP>lb<SP>Gross<SP><CR><LF>
• In BMI mode (displaying the BMI value), the scale will send out the following data:
GROSS WEIGHT 215.0 LB
TARE WEIGHT 0.0 LB
NET WEIGHT 215.0 LB
PATIENT HEIGHT 6-01.0 FT
PATIENT BMI 28.4
7.2 Standard Remote Protocol (configuration option #9 set to 1)
When connected to a computer, there are five commands that can be used in the standard remote protocol to
communicate with the scale. They are:
• t - tare the scale. If in gross mode, will tare and go to net mode. If in net mode, will remove tare and
return to gross mode.
• w - the scale sends the actual weight to the computer.
• i - the scale sends the software ID of the scale.
• z - the scale will be set to zero (0.0) if possible.
• p - the scale sends the same data as a pushbutton keypad print.
The format of the returned data will be the same as noted under the pushbutton keypad print. Note that the w and
p commands will not return a value if the scale is in motion, or displaying an invalid weight.
18 Bariatric Wheelchair Technical and Operating Manual
Page 23
7.3 ESC Protocol (configuration option #9 set to 0)
The ESC Protocol differs from the standard protocol and enables weight and unit of measure data to be
transmitted for full integration into electronic medical records or for diagnostic testing of the battery life, load
cells, etc. The scale will only transmit data upon receiving the proper command set.
You can test the command set and review the scales’ response using either PROCOMM Plus or the Dietary/
Fitness files foun
set up "hot" keys for the commands. Refer to Table 7-1 for a listing of those commands.
An Escape Protocol is where the escape <ESC> is used to indicate
data.
Table 7-1 lists a complete list of ESC commands that are
d on our web site, www.ricelake.com/health. If using PROCOMM Plus, we recommend you
that there is a command following and not just
used with the scale.

Rice Lake Bariatric Wheelchair Scale Limited Warranty
Rice Lake Weighing Systems (RLWS) warrants that all RLWS equipment and systems properly installed by a
Distributor or Original Equipment Manufacturer (OEM) will operate per written specifications as confirmed by
the Distributor/OEM and accepted by RLWS. All systems and components are warranted against defects in
materials and workmanship for two years.
RLWS warrants that the equipment sold hereunder will conform to the current written specifications authorized
by RLWS. RLWS warrants the equipment against faulty workmanship and defective materials. If any equipment
fails to conform to these warranties, RLWS will, at its option, repair or replace such goods returned within the
warranty period subject to the following conditions:
• Upon discovery by Buyer of such nonconformity, RLWS will be given prompt written notice with a
detailed explanation of the alleged deficiencies.
• Individual electronic components returned to RLWS for warranty purposes must be packaged to
prevent electrostatic discharge (ESD) damage in shipment. Packaging requirements are listed in a
publication, Protecting Your Components From Static Damage in Shipment, available from RLWS
Equipment Return Department.
• Examination of such equipment by RLWS confirms that the nonconformity actually exists, and was
not caused by accident, misuse, neglect, alteration, improper installation, improper repair or
improper testing; RLWS shall be the sole judge of all alleged non-conformities.
• Such equipment has not been modified, altered, or changed by any person other than RLWS or its
duly authorized repair agents.
• RLWS will have a reasonable time to repair or replace the defective equipment. Buyer is responsible
for shipping charges both ways.
• In no event will RLWS be responsible for travel time or on-location repairs, including assembly or
disassembly of equipment, nor will RLWS be liable for the cost of any repairs made by others.
THESE WARRANTIES EXCLUDE ALL OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING WITHOUT
LIMITATION WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE. NEITHER
RLWS
NOR DISTRIBUTOR WILL, IN ANY EVENT, BE LIABLE FOR INCIDENTAL OR CONSEQUENTIAL DAMAGES.
RLWS AND BUYER AGREE THAT RLWS’S SOLE AND EXCLUSIVE LIABILITY HEREUNDER IS LIMITED TO
REPAIR OR REPLACEMENT OF SUCH GOODS. IN ACCEPTING THIS WARRANTY, THE BUYER WAIVES ANY AND
ALL OTHER CLAIMS TO WARRANTY.
SHOULD THE SELLER BE OTHER THAN RLWS, THE BUYER AGREES TO LOOK ONLY TO THE SELLER FOR
WARRANTY CLAIMS.
NO TERMS, CONDITIONS, UNDERSTANDING, OR AGREEMENTS PURPORTING TO MODIFY THE TERMS OF THIS
WARRANTY SHALL HAVE ANY LEGAL EFFECT UNLESS MADE IN WRITING AND SIGNED BY A CORPORATE
OFFICER OF RLWS AND THE BUYER.
