OPERATING INSTRUCTIONS
IMPORTANT: To prevent falls or injury, place the scale securely far from the edge of the
counter, table or other flat surface used to hold the scale. Do not let the scale touch the
wall or any other object near or around the scale while it is in use.

begin to display weight information and will lock on the patient’s weight when the stable
weight of the patient is determined. Depending on the movement of the patient on the scale,
it may take several seconds for the scale to lock onto the weight.
4. When a stable weight is calculated, a small ring along with the word “HOLD” will appear on
the display and the weight of the baby will lock.
4. Note: If the display shows “OVER” you have exceeded the capacity of the scale.

6. To return the scale to 0.0, press the RELEASE button and the scale will be ready to weigh
again.
Note: If “Lo” appears on the display, it indicates that the battery power is low. It does NOT
indicate a problem with the weight measurement.
Note: If Auto Off is enabled the scale will not power off if a weight is held on the display.
Press the RELEASE button to release the weight and allow the scale to power off
automatically.
Zero/Clear (TARE) Function
The tare function allows you to place other items on the scale while weighing the baby, without
affecting the baby’s weight reading.

2. Press and release the ZERO/CLEAR button. The word “TARE” will appear on the display
and the display will return to 0.0.
3. Place the baby on the scale with the tared item and weigh normally. The scale will only
display the baby’s weight.

MAINTENANCE
Maintenance
The following pages provide instructions for maintenance, cleaning, calibrating, and
troubleshooting of your 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.
3. Do not store the scale on its side.
4. This scale contains electronic parts. Use it carefully. Do not drop, kick or jump on it.
5. Do not store near chemicals, heaters or radiators.
Note: This scale is an extremely sensitive weighing device. If the auto-off function is disabled,
battery power will be consumed. Items such as clothing or towels place or dropped on the scale
may cause it to activate. To prevent run down of the batteries, 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.
