POSSIBLE CAUSE

1.Battery problem

2.Bad Power Supply or Not Plugged In

3.Electrical Outlet not functioning

The batteries are low

1.External object interfering with the scale

2.The display did not show “0.0” before weighing

3.Scale is not placed on a level surface

4.Scale is out of calibration

Overload. The load on the scale exceeds scale capacity (500 lbs / 220 kg)

Negative weight, indicating a tare was present. Load on the scale is below initial zero point

CORRECTIVE ACTION

1.Check / Replace the batteries

2.Check / Replace Power Supply Adapter

3.Use a different outlet

Replace batteries according to instructions

1.Remove interfering object from the scale

2.Ask the patient to step off the scale. Zero the scale and begin weighing process again.

3.Place scale on level surface

4.Check weight with know weight value Remove weight, turn scale off, turn scale on again and try again

CALIBRATION

This scale has been factory calibrated and does not require calibration prior to use.

The calibration procedure may be performed using a known weight in either pounds or kilograms. Simply set the scale for the desired unit of measure using the lb/kg key and start the calibration procedure. The calibration is performed using lb or kg, according to the unit of measure used upon entering into the calibration path, meaning the scale will default to either lb or kg, if that was the setting left on the scale for weighing. Note: Calibration weight must be no less than 100 lb (40 kg) and no more than 500 lb (200 kg).

ACTION

Press and hold the LB/KG and ZERO buttons at the same time, then press the ON/OFF button to turn on the scale. “CAL” followed by a number indicates you can calibrate.

Press the ZERO button. “C-100” (for lb mode) or “C-40” (for kg mode) will flash on the display and then the display will return to “0”.

Place 100 lbs or 40 kg on the scale and when calibration number stabilizes, press the ZERO button. “C-200” (for lb mode) or “C-80” (for kg mode) will flash on the display and then the display will return to “0”.

Place 200 lbs or 80 kg on the scale and when calibration number stabilizes, press the ZERO button. “C-300” or “C-120” will appear on the display and then the display will return to “0”.

Place 300 lbs or 120 kg on the scale and when calibration number stabilizes, press the ZERO button. “C-500” or “C-200” will appear on the display and then the display will return to “0”.

Place 500 lbs or 200 kg on the scale and when calibration number stabilizes, press the ZERO button. “ END ” will appear on the display and then the scale will automatically turn off.

DISPLAY SHOWS
