CAUTIONS AND WARNINGS
• To prevent injury, never leave patient unattended while on the scale.
• For accurate weighing the scale must be placed on a flat, stable surface.
• For accurate weighing, verify proper operation according to the procedure described in this
manual before each use.
• Do not use in the presence of flammable materials.
• Do not transport the scale with any weight on the platform.
• Do not exceed recommended weight limit of 600 lb / 272 kg for this scale.
• Operating at other voltages and frequencies than specified could damage the equipment.
• If the “LO BAT” indicator activates, for accurate weighing, replace the batteries or connect
the scale to an AC power source.
• If the scale becomes damaged, it should not be operated until properly serviced. All repairs
should only be performed by authorized Health o meter® Professional service personnel.
• When replacing / inserting batteries, be sure to use all new batteries.
• To prevent patient injury, the patient must be attended throughout the entire weighing
event.
• Operate this scale exclusively with the AC adapter provided by Health o meter®
Professional. Use of an unspecified adapter will void the warranty, and can pose a serious
safety hazard.
• For use with AC adapter model ADPT31.
• Prior to using this scale, inspect the AC adapter cord for cracking / fraying, or for broken /
bent plug prongs.
• Prior to using this scale, ensure that the AC adapter is plugged into an outlet with the rated
voltage appropriate for operation.
• Ensure that the AC adapter and scale do not come in contact with liquids, excessive
temperature, or excessive humidity.
• Unplug the AC adapter, and carefully store both the adapter and adapter cord before
moving the scale.

Tare Function
When using this scale, the weight of an object, such as a blanket, can be subtracted
from the total weight in order to determine the weight of the patient alone. Ensure that
the edges of the object are on the scale and not touching the floor.

CALIBRATION
This scale has been factory calibrated, and does not require calibration prior to use. If
required, the scale can be calibrated. The following calibration assumes the scale is set to
pounds, and 200 lb is employed as the calibration standard.
Note: Only weights certified and traceable to national standards are to be used for
calibration procedures.
Scale Calibration
ACTION
DISPLAY SHOWS
Press and hold the REWEIGH and ZERO buttons at the same
time, while pressing the ON/OFF button to turn on the scale.
“LOAD” will briefly appear on the display, followed by “200.0
LB” indicates you can calibrate. Release all three buttons.
“LOAD” followed by
“200.0 LB”
Ensure there is no weight on the scale (except for the rubber
mat) and press the REWEIGH button. “Clear” will flash on the
display, followed by “--------”. At this time the scale is
calculating zero calibration. After zero calibration, the display
will flash “PUT” followed by “200.0 LB”.
“Clear” followed by
“-------”. Then “PUT”
followed by “200.0 LB”
Place 200 lb on the scale. Then press REWEIGH. “CAL” will
appear on the display, followed by “FAC” followed by 5 digits.
The calibration factor should be in the range between 8000
and 10000 If the number is out of that range, contact
Customer Service at 1-800-815-6615.
“CAL” followed by “FAC”
followed by “X.XXXX”.
If the calibration factor is within range, press the REWEIGH
button. “DONE” will appear on the display, followed by
“START”, followed by “0.0”. Remove the weight from the
scale.
“DONE” followed by
“START”, followed by
