Special Features

Tanita Corporation’s electronic scales come standard with these special features:

1.Autozero: The scale will automatically display “0” when turned on. If a foreign object is placed on the platform before turning the scale on, it will automatically zero out that object’s weight.

2.English-Metric Readout: You may switch between metric (kilos) and English (pounds) readouts before or after a reading, and the scale will convert one reading to the other.

3.Recalculate Weight: If the first reading of a patient’s weight is suspect, a second reading can be taken without removing the patient from the scale. To reweigh the patient, simply depress the Zero switch.

4.Average Weight: In most cases, the scales display an actual weight based on a series of consistent stable measurements. However, if the wheelchair/patient keeps moving, the scale may not get the readings required to give a “stable weight.” In these instances an average weight can be determined by activating the Average Locking feature. Depress the Pounds (or Kilos) switch (dependent upon measurement mode). The indicator light should start flashing. A weight should appear in place of the moving dashes. Depress the Pounds or Kilos switch again to deactivate the feature.

5.Zero Ability: The operator can zero out the weight of a chair, etc., upon which a patient is to be weighed.

OPERATING INSTRUCTIONS

As a Wheelchair Scale

When using the 4500 Wheelchair Scale, the weight of the wheelchair must be taken into account. Weigh the wheelchair by itself to determine its weight and then subtract this weight from the combined weight of patient and wheelchair.

IMPORTANT: Adjust platform height so that ramp does not touch floor or carpet. An incorrect weight reading will result if the ramp touches the floor or carpet. (See Section “Leveling the Platform” on page 3.)

Weighing the Wheelchair

1.Turn scale on by depressing the On/Off switch. Wait for the display to show “0.”

2.Roll the empty wheelchair onto the scale. Wait for the moving dashes to lock in and display the weight of the wheelchair.

3.Record the wheelchair weight.

4.Remove the wheelchair from the scale platform and turn scale off.
