1.0 Introduction
The 250-10-2 bariatric 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 weight is displayed on the indicator and
can be displayed in pounds or kilograms.
Manuals, resources and warranties are available from Rice Lake Weighing Systems website at
www.ricelake.com/health

Assembly

2.0 Assembly
2.1 Unpacking Scale
A minimum of two people should transport, unpack and assemble the scale for their own personal safety and ensure the
integrity of the scale. Place the unopened box in an open area that has ample room for unpacking the scale. Use caution while
removing packaging and unpacking the scale. After unpacking, visually inspect the 250-10-2 bariatric handrail scale to ensure
all components are included and undamaged. If parts were damaged in shipment, notify Rice Lake Weighing Systems and the
shipper immediately.
Parts contained in the shipping box include:
• The scale
• This manual
• 6 mm Allen key
• Six AA non-rechargeable batteries
2.1.1 Repackaging
Retain the packaging for use in the event that the scale must be returned or moved. The product must be properly packed with
sufficient packing materials. Whenever possible, use the original carton and packing materials when shipping the scale back.
Damage caused by improper packaging is not covered by the warranty.
2.2 Scale Setup
Use the following steps to set up the bariatric handrail scale.
1. Move the box 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.
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.
Do not lift the scale out of the box by its handle as this can cause the hinges to break.
3. Gently place the scale platform down to the floor.
4. Loosen the handles using the supplied Allen key, unfold handles and set upright.

2.2.1 Adjusting Scale Feet
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.
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. By not having clearance around the scale base will cause inaccurate
weighments.
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.
2.2.2 Insert Batteries
The six AA batteries supplied with the scale provide an average of 25 hours of continuous use.
To install the batteries:
1. Turn thumbscrew counterclockwise then remove battery cover.
2. Insert batteries into the battery chamber as illustrated.
Figure 2-2. Battery Chamber
3. Put the cover in place and turn the thumbscrew clockwise to secure.
Remove the batteries prior to storing if the product is not going to be used for an extended period of time.
If the LO BAT indicator activates, for accurate weighing, replace the batteries or connect the scale to an AC power
source as soon as possible.
2.2.3 Power Connection
An optional AC power adapter can be used when a power outlet is available.
Only use power adapters supplied by or purchased from Rice Lake Weighing Systems. The use of a power
adapter not from Rice Lake Weighing Systems voids the warranty.

The battery annunciator on the display turns off when using an AC power connection.

3.0 Operation
This section describes the front panel and includes procedures for operation of the scale.
Figure 3-1. Front Panel Keypad
3.1 Key Descriptions
The display has 10 front panel keys. Key functions are described in the table below.
The front panel keys are very sensitive, so only a gentle press is required.
Key Name Function
On/Off Powers the scale on or off
Print
LB/KG
Sends data out from the RS-232 port; Allows to toggle between kilograms and pounds providing that it is enabled in
Configuration mode; Cannot toggle while in the BMI mode
Zero Only functions if the current weight is stable and less than 2% of the capacity of the scale. Anything over 2% requires
a recalibration
Hold Release Displays most current weight value on the display and holds that value when the patient is off the scale. A second
press releases the weight value. Not active while in BMI mode
BMI Pressing the BMI key enables access to the BMI (Body Mass Index) mode (defaults when scale is turned on). The
patient is gets on the scale, weight stabilizes and press the BMI key. The display then asks for the patient height to
calculate out the patient BMI.
TARE Used to remove the weight initially of anything on the scale that shouldn’t be included in the total weight of the
patient on the scale
CLEAR When using the BMI function, the display looks for a height entry. Pressing Clear changes this entry back to 190.0
cm (default) or 5 ft, 7.5 in.Once BMI is displayed, pressing the Clear key exits BMI
ENTER Used to accept height in BMI mode; accepts the value of the parameter last entered and moves to the next stage
Pressing and holding Enter during startup will display ID. This is the first setup on entering into configuration mode
Up Arrows Adjusts the value of the flashing digit/number
Adjusts height input (0.5 in/0.5 cm) while in BMI mode

2. Press once the patient’s weight stabilizes. The patient’s weight and the HOLD and LOCK annunciators remain
on the display when the patient is off the scale.
3. Press again to return the scale to zero.
Pressing will not work while using Hold/Release function.
Pressing prior to the patient getting on the scale will also hold the weight display.
3.4 Preset Tare
Use the following steps for the Preset Tare function prior to patient weighing if additional items are being used by the patient.
1. Press to turn on the scale. 0.0 appears on the display along with the ZERO annunciator.
2. Place additional item(s) on the scale.

is still active. The weight of the additional item(s) remains stored in memory for the duration of this weigh in.
6. To cancel the tare weight, remove patient from the scale and press until NET disappears from the display and
the display turns back to 0.0 and GROSS appears.
Tare weight is also canceled when the scale is turned off.
3.5 Toggle Tare
