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 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 hex wrench
• 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 bariatric handrail scale with seat.

1. Move the box into the area where the weighing process will occur.
2. NOTE: Place the scale on a hard, level surface for the most accurate weighments. Thin carpeting is acceptable, but not recommended.
3. With two people lifting the scale by its base, remove from packaging.
4. IMPORTANT: Do not lift the scale out of the box by its center rail as this can cause the hinges to break.
5. Gently place the scale platform down to the floor.

Use the supplied hex wrench to loosen the screw on both center rail hinges.

Raise the center rail to the upright position.

Tighten the screw.

Insert a screw through the center rail joint location.

Place the handrail connector over the screw.

IMPORTANT: The connector has a narrow and thick side. Ensure the narrow side is facing up when placing the connector over the screw so it lies flush with the center rail.

Tighten the screw into the handrail.

Place screw cap over the screw head.

Repeat Steps 7-10 on the other center rail joint locations.

Tip the scale back to access underneath the base.

Line up the handrail ends with the base screw holes.

Install handrail base screws through the base into the handrail.

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 bariatric handrail scale 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 2-4.

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.

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 Print for at least three seconds, or until the scale emits two quick beeps.

NOTE: If the scale does not beep after five seconds, release Print 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

[Table: Print Format Tokens with Token, Description: XXXXXXXXX (Weight with decimal point and “-” sign), (Space), uu (Unit - Ib or kg), mmmmm (Mode - gross or net), (Carriage return), (Line feed)]

Example:

60.1 KG= -60.1KG

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:

-60.1KG
