Introduction

The 250-10-4 barbaric handrail scale with fold down chair seat 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 fold down chair allows patients to sit down while being weighed. The scale is set up to use motion sensing 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 and has a 1,000 lb capacity.

Assembly

Unpacking

A minimum of two people should transport, unpack and assemble the scale for their own personal safety and to ensure the integrity of the scale. Use caution while removing packaging and unpacking the scale. After unpacking, visually inspect the 250- 10-4 barbaric handrail scale with seat 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

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.

IMPORTANT
Damage caused by improper packaging is not covered by the warranty.

Scale Setup

Use the following steps to set up the barbaric handrail scale with seat.

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 weightiness. 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.
   IMPORTANT Do not lift the scale out of the box by its handle as this can cause the hinges to break.

3. Gently set the scale platform down to the floor.

4. Loosen the handles using the Allen key and unfold and set upright (handles shown in Figure 2-1).

5. Tighten the two hinges on the scale by rotating the two handles. This will secure the handrail mounted indicator.
   Figure 2-1. Secure the Handrail by Tightening the Durable Hinges
   

6. Screw in all four legs.

7. Attached the wrap around rails.

8. Tighten the hex screw head using the enclosed 6 mm Allen key to stabilize the scale.

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.

Unfold Platform Seat
The 250-10-4 comes with a fold down seat for those patients who need to be weighed while seated. To unfold the seat, simply pull down on the seat bottom as shown in Figure 2-2.

Figure 2-2. Unfolding the Seat

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 2-3. 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.

Power Connection

An optional AC power adapter can be used when a power outlet is available.

IMPORTANT
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

Communication

The unit 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. That connection is shown in USB Connection section on the next page.

The RS-232 parameters are:

• 9600 baud (selectable in the programming mode)
• 8 data bits
• 1 stop bit
• no parity
• no handshaking

There are three methods of communication:

• Push-button keypad print
• Standard remote protocol
• Escape protocol

Push-button Keypad Print
With a stable, in-range weight, press and hold for at least three seconds, or until the scale emits two quick beeps. If the scale does not beep after five seconds, release 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: xxxxxxxxxuummmmm

Example: -10 Lb net = -10.0lbNet 10 Lb gross = 10.0lbGross

The scale will send out the following data while in BMI mode (displaying the BMI value)

USB Connection
The scale has the capability of connecting to a Windows® computer (PC) using a USB cable (not included) and a terminal emulation program. A terminal emulation program allows the transfer of data between the scale and  PCusing a serial port

Apple® and Macintosh® computers are unable to transfer the necessary data to the scale. Only use a PC for data transfer. Connecting software and downloads should always be addressed by the IT department for safety reasons and can vary depending on what type of computer platform is being used.
Consult the IT department if driver protections are preventing the use of the USB driver. Driver protections may need to be temporarily disabled on Windows 10 or later computers to allow for the installation of the USB driver.

1. Connect the scale’s indicator to a PC using a USB-Type B to USB-Type A cable (not included).

2. Turn the indicator on.
   In most cases, the PC should find the driver and automatically configure the driver when the scale is plugged into a USB port.

3. Open a terminal emulation program, such as Advanced Serial Port Terminal, pUtty or Hercules (used in this example).

4. Connect to the serial port assigned by the PC (COM5 in example). This can be found in Device Manager. Once selected, press Open.
   

5. With weight on the scale, press and hold the Print button on the indicator for three seconds. The patient’s weight is sent to the PC
