Setting Auto Zero Option
When a scale is set to zero, it creates a reference point for weights that are placed on it. There are
two approaches to how this can take place. This option allows the user to select whether the scale
will re-set itself to ZERO each time it is powered up or whether it will use the zero reading from the
last time it was zeroed.
“Enable” means the scale will zero itself when it is powered on and this may take a few seconds.
After each use, the scale will clear the weight of the patient and set itself back to the initial ZERO
level it found on start-up. Health o meter® Professional recommends keeping this setting as
Enable. Note: Hitting a key to wake the scale from sleep mode will not prompt the scale to zero.
“Disable” means the scale does not attempt to find a zero when powered on, rather it will use the
last zero setting it had from its most recent use. There will be no delay in using the scale if the
Auto Zero is disabled. Health o meter® Professional recommends that if the Disable option is
selected, users should manually zero the scale before each weight measurement by
pressing . Users will see dashes appear on the screen as the scale is finding zero.

Help
This scale has been factory calibrated, and does not require calibration prior to use.
There are no requirements for calibration in the field; users should adhere to their
institution’s calibration policies.
Calibration of your scale can be performed using calibrated kilogram (kg) or pound (lb)
weight standards. Minimum calibration is 200 lb / 100 kg. Maximum calibration weight is
1000 lb / 454 kg. The required calibration standard will be the Unit of Measure (UOM)
for which the scale is configured. KG models can only be calibrated in kilograms. If
Everlock® is engaged the scale can only be calibrated in the locked unit of measure.
Note: Only weights certified and traceable to national standards should be used for
calibration.
Warning: Always ensure that the scale is returned to the correct UOM after scale
calibration.
