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).
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.
