CALIBRATION

This scale has been factory calibrated and does not require calibration prior to use.
For maintenance, the calibration procedure may be performed using a known weight in kilograms.

press the ON/OFF button to start the scale. When "CAL" appears in the display, release the
Kg/LB and ZERO/CLEAR buttons.
Press the ZERO/CLEAR button. "C-5" will flash on the display and then the display will return
to "0".
Place 5 kg on the scale and when calibration number displayed stabilizes, press the
ZERO/CLEAR button. "C-10" will flash on the display and then the display will return to "0".
Place 10 kg on the scale and when calibration number displayed stabilizes, press the
ZERO/CLEAR button. "C-15" will flash on the display and then the display will return to "0".
Place 15 kg on the scale and when calibration number displayed stabilizes, press the
ZERO/CLEAR button. "C-20" will flash on the display and then the display will return to "0".
