The scale is set up to use motion sensing technology, to determine actual weight of a moving patient. The weight can be displayed in pounds or kilograms and you can enter a tare weight. Section 3.0 on page 6 of this manual explains the scale operation and how to obtain a tare weight.

The wheelchair scale has a unique folding feature that enables easy transportation and simplifies assembly, avoiding the need for field wiring and recalibration. All that is required is to open the packaging and unfold the scale.

Assembly

IMPORTANT

CAUTION

IMPORTANT

2.0 Assembly

2.1 Unpacking

Place the unopened box in an open area that has ample room for unpacking the scale. Recommended tools needed to set up your scale include:

• Scissors or a box cutter

Using scissors or a box cutter, cut the strapping bands that secure the box together. Immediately after opening the box, visually inspect the scale and components to ensure all parts are included and undamaged.

Parts contained in the shipping box include:

• Scale

• Box containing six AA batteries and four feet

2.2 Repacking

If the Rice Lake Digital Wheelchair Scale must be returned or moved, it must be properly packed with sufficient packing materials. When possible, use the original carton and packing material.

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

2.3 Setup

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 acceptable, but not recommended.

Rice Lake recommends using two people for lifting the scale and to use proper lifting techniques to prevent injury.

Do not lift the scale out of the box by its handle as this can cause the hinges to break or affect the scale operation.

1. Using two people, lift the scale out of the box by the base.

2. Stand the scale on edge to remove the packing material.

IMPORTANT

3. Screw the four feet clockwise into the scale base as far as possible.

4. Turn each foot counterclockwise two full rotations, to ensure there is adequate clearance between the scale and the floor.

5. Lower the scale base down to the floor carefully. There should be minimal clearance between the scale base and the floor. Figure 2-2 shows the width of a finger being slid between the scale base and the floor.

Not having clearance around the scale base creates inaccurate weighments.

Figure 2-2. Clearance Between Scale Base and Floor

6. Gently press down on all corners of the scale base to ensure there are no high spots or rocking of the scale base. The scale must be completely level.

An unleveled base produces inaccurate weight readings.

7. Turn the knobs to loosen the hinges and raise the handle.

8. Tighten the knobs to secures the handrail and the indicator mounted on it.
