SETUP / BATTERIES
Preparing the 500KL Scale for Use
Replacing / Inserting Batteries
1. Remove the protective plastic film covering the display (the film says “FACTORY
CALIBRATED”).
2. Unplug the optional AC adapter, if connected to a power source.
3. With a Phillips head screwdriver remove the screw from the battery compartment cover and
remove the battery cover on the back of the display assembly by pressing the locking tab (see
Figure 12).
4. Replace or install the batteries with new units. Health o meter®Professional recommends
using an alkaline or lithium battery, rated for 130°F (54°C) operation. Do not use zinc-carbon
batteries.
5. Re-attach the battery cover to the display assembly.
6. Ensure all objects are removed from the scale’s assembly, and then press the ON/OFF
button to turn the scale on. The display will show “Start”, then “0.0” LB or “0.0” KG. Press the
LB/KG button to select the weight mode (LB or KG).
Note: This scale will always default to the settings and units last used (LB or KG).
Note: If the set up procedure failed, refer to the troubleshooting instructions. If the problem is
not corrected, refer to qualified service personnel.
Warning: If the scale will not be used for some time, remove the batteries to avoid a
safety hazard. Disposal of batteries must be performed in accordance with the prevailing
national, regional or local regulations which apply to you.
Optional AC Adapter
1. Connect the AC adapter (not included) into the adaptor jack on the scale platform C(see
Figure 7).
Warning: To avoid a safety hazard, use AC adapter model ADPT30WA (International, plug
kit) or ADPT31 (Domestic, USA).
2. Plug the scale’s AC adapter into the power source.
3. When the AC adapter is disconnected from the scale, the scale will switch to battery power if
batteries are installed.

QUICK START / OPERATING INSTRUCTIONS (CONT)
Weighing a Patient
Note: When this scale is turned on, it will always default to the settings and units last used (LB
or KG).
1. Make sure there is no object on the scale platform.
2. Press the ON/OFF button to turn the display assembly on.
3. Wait until the “0.0” LB or “0.0” KG appears on the display.
4. Ask the patient to step on the scale. The scale will 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.
Caution: To prevent patient injury, the patient must be attended throughout the entire
weighing event.
5. The weight may be held on the display by pressing the HOLD/RELEASE button. To release,
press the HOLD/RELEASE button again.
6. After the weight measurement has been taken and is recorded, have the patient step off the
scale.
7. Press the ON/OFF button to turn the scale off.
BMI Function
Body Mass Index is another name for Quetelet Index, a formula that is a convenient indicator of
BMI with various exemptions, such as athletes, children, the elderly, and the infirm.
Note: The scale will not calculate BMI for a patient that is 24 pounds (12 kg) or less. If a height
is not entered for the patient within 30 seconds of pressing the BMI button, the scale will return
to the normal weighing mode.
1. Make sure there is no object on the weighing platform.
2. Press the ON/OFF button to turn the scale on.
3. Wait until the “0.0” LB or “0.0” KG appears on the display.
4. Ask the patient to step on the scale. The scale will 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.
5. After obtaining the patient’s weight on the scale, press the BMI button while the scale is on.
6. The scale will prompt you to enter the patient’s height. Use the keypad ▲and ▼buttons to
enter the patient’s height.
Note: When weighing in pounds, the height is displayed in inches. When weighing in kilograms,
the height is displayed in centimeters.
7. Once height is keyed in, press the ENTER button.
8. The display will show the patient’s BMI.
9. Press the CLEAR button to return to the normal weighing mode of the scale.

QUICK START / OPERATING INSTRUCTIONS (CONT)
Zero Function
When using this scale, the weight of an object, can be zeroed out allowing additional weight to
