the estimated height of the patient. Then
raise the headpiece into its horizontal
position. Note: For patients under 48.5” /
123 cm, slide the headpiece down the pillar.

2. Position the patient facing the display head.

Ensure that the patient’s posture is upright,
and that the patient’s head is straight and

level. Slide the headpiece down until it rests
on the patient’s head.

3. Determine the patient’s height by reading
the value on the measuring strip nearest to
the line on the red indicator, as shown
below. For heights greater than 48.5” /
123 cm, the height measurement is read at
the red line on the pillar. For heights less
than 48.5” / 123 cm, the height
measurement is read at the red line on the
headpiece.

For heights less than 48.5” / 123 cm

For heights greater than 48.5” / 123 cm

CAUTION: Use caution when sliding height rod up and down. The rod should move
smoothly; do not move the rod in a jerking motion. Fold headpiece down when not in
use.

Maintenance

The following pages provide instructions for maintenance, cleaning, calibrating, and
troubleshooting of the scale. Maintenance operations other than those described in this manual
should be performed by qualified service personnel.

Caution: Before first use, or after long periods of non-use, check the scale for proper
operation and function. If the scale does not operate correctly, refer to qualified service
personnel.

1. Check overall appearance of the total scale for any obvious damage, wear, and tear.

2. Inspect the AC adapter cord for cracking or fraying, or for broken/bent prongs.
Note: This scale is an extremely sensitive weighing device. Items such as clothing or towels
placed or dropped on the scale may cause a scale to activate. In order to prevent battery
depletion, do not store or leave anything on the scale.

Cleaning and Disinfecting

Proper care and cleaning is essential to ensure a long life of accurate and effective weighing.

1. Health o meter® Professional recommends using one of the following solutions on a soft
cloth or disposable wipe:

● mild soap and water solution

● 70% isopropyl alcohol

● solution with 1-5% hydrogen peroxide concentration

After cleaning/disinfecting, wipe with a cloth dampened with water and then with a clean dry
cloth. To avoid residue build-up or damp surfaces, ensure all scale parts are completely dry
after cleaning.

2. Never use rough or abrasive materials to clean the scale, as these will damage the scale’s
finish.

3. Do not submerge the scale in water or any other liquid.

4. Do not pour or spray fluids directly on the scale.

This scale has been factory calibrated, and does not require calibration prior to use.
If required, the scale can be calibrated. Calibration of your scale is performed using kilograms
(KG) or pounds (LB), according to the units of measure used upon entering into the calibration
path. When calibrating in pounds, a total of 500 lbs is required (or 300 lbs for newer models),
applied in increments of 100 lb, 200 lb, 300 lb and 500 lb. If calibrating in kilograms, a total of
200 kg is required (or 120 kg for new models), applied in increments of 40 kg, 80 kg, 120 kg and
200 kg. THE 500KG CAN ONLY BE CALIBRATED IN KILOGRAMS.

Note: Only weights certified and traceable to national standards are to be used for
calibration procedures.

*For scales with date codes higher than 1515, only 300 lb (120kg) of weights are required
for calibration. Refer to the white label on the back of the display head to determine your
scale’s date code. Example: Date Code 4215, calibration procedure is complete after 300
lb (120 kg).
