ii Handrail Scale Technical and Operating Instructions
1.0 Introduction
The Rice Lake Digital Handrail Scale is designed for weighing bariatrics and ensures sound, accurate weighing
information. A non-skid platform paired with side rails assists persons who need extra support and safety. The
scale is set up to use motion sensing weighing technology, to determine the actual weight of a moving patient.
The weights is displayed on the indicator and can be displayed in pounds or kilograms.
This manual can be viewed and downloaded from the Rice Lake Weighing Systems web site at
www.ricelake.com/health. Rice Lake W
eighing Systems is an ISO 9001 registered company.

2.1 Unpacking Your Scale
Place the unopened box in an open area that has ample room for unpacking the scale.
Parts contained in the shipping box include:
• The scale
• This manual
• Small box containing AC adaptor and RS-232 cable
• 6 mm Allen Key
2.2 Repacking
If the Digital Handrail 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.
NOTE: 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 Handrail Scale.
1. Locate the operation manual from inside the box and set aside as i
proper set up.
2. Using two people, remove the scale out of the packaging material that
of the box by the scale base.
NOTE: DO NOT lift the scale out of the box by its handle as this can cause the hinges to break.
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. Gently set the scale platform down to the floor
5. Loosen the handles using the Allen key and unfold handles and set upright.

Retaining Screw
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 2-2.
Figure 2-2. LED Light Location
.
The AC adaptor, when not in use, plugs into the back housing of the indicator for storage. Figure 2-2 shows that
location.
The Digital Wheelchair Scale is capable of running its internal sealed lead-acid rechargeable battery if no
additional power source i
s 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.
NOTE: 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.
Connect the load cell into the load cell connection point. You will he
Put the back on the indicator and secure with the four back cover screws that were previously set aside.
2.4 Getting Ready to Weigh a Patient
Once the scale is properly unpacked and set up, and prior to weighing a patient, step on the scale to check the
scale that all functions are working correctly. The scale is calibrated from the factory so simply turn on the scale
and step on the scale to get a weight reading. Press the

Key Name Function
ON-OFF/ZERO ON-OFF - Switches the scale on or off
ZERO - Clears weight off the scale and returns it back to zero.
BMI/TARE BMI - Enables the user to access the BMI (Body Max Index) function.
TARE - Used to subtract a weight off the scale ie: wheelchair
REWEIGH Allows you to reweigh a patient without having them leave the scale.
Kg-Lb/PRINT Allows the user to toggle between kilograms and pounds.
Press this key to print a weight if connected to a printer.
Table 3-1. Key Functions
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.

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 assess
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.
Ex
ample: weight = 150 lbs, height = 5’5 (65")

Calculation: [150
÷ (65)
] x 703 = 24.96

203 lbs or more 30 or higher Obese
Table 3-3. BMI Ranges and Weight Status Example
Use the following steps in determining the BMI.
1. To use the BMI function, weigh the patient as described under Weighing (above)3.1 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

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
decrease by 0.5 cm increments.

6.0 RS-232 Communication
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. Figure 2-2on page 2 shows where the RS-232 connection is.
The RS-232 parameters are 9600 baud (selecta
and no handshaking.
There are three methods of communication:
• Pushbutton keypad print
• Standard remote protocol
• Escape protocol
6.1 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.
• If displaying weight and not BMI, the scale will send
xxxxxxxxx<SP>uu<SP>mmmm
Where:
xxxxxxxxx is the weight with decimal point and " - " si
mmmmm is the mode (gross or net)
Examples:
-10 Lb net = <SP><SP><SP><SP>-10.0<SP>lb<SP><SP>Net<SP><SP><SP><CR><LF>

ble in the programming mode), 8 data bits, 1 stop bit, no parity

gn, if negative uu is the unit (lb or kg).
• 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
6.2 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 ne
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 un

6.3 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 found on our web
