OPERATING INSTRUCTIONS (CONTINUED)
BMI Function
Body Mass Index (BMI) is a ratio between a person's weight and height and interpreted as a BMI
score. This BMI score is then used as a tool to categorize a patient as underweight, normal,
overweight, obese or morbidly obese.
Note: The scale will not calculate BMI for a patient that is 24 pounds (12 kg) or less.
Note: If a height is not entered for the patient within 30 seconds of pressing the BMI button and
no weight is on the platform, the scale will return to the normal weighing mode.
1. With all weight off the scale, press the ON/OFF button to turn on the scale.
2. "StArt" will briefly appear on the display, followed by "0.0" LB or "0.0" KG.
3. Assist the patient onto the scale. The scale will begin to display weight information. When a
stable weight is determined, "LOCK" will appear along with the patient's weight. Depending
on the movement of the patient on the scale, it may take several seconds for the scale to
lock onto the weight.
4. After obtaining the patient's weight and with the patient remaining on the scale, press the
BMI button.
5. The display will show 65.0" (in LB mode) or 150.0 cm (in KG mode). Use the keypad ▲ and
▼ buttons to enter the patient's height in inches if weighing in LB or centimeters if weighing
in KG. To determine the patient's height, follow the height measuring instructions on page
18.
6. Once height is keyed in, press the ENTER button.
7. The display will show the patient's BMI.
8. Press the CLEAR button to return to the weighing mode.
