Calibration
When precision weighing is needed, calibrate the scale as follows:
First take away the object from the platform, then press ON/TARE key to set the display to zero, press and hold
ON/TARE key until “
CAL
” is display, then release, the scale will display "
CAP
”. Press ON/TARE key to switch between
"
LINE
" or "
CAP
", and press ON/TARE key to confirm.
Note: "
LINE
” means to do the liner calibration, and “
CAP
” means to do the sensitivity calibration.
5.1 Liner calibration
When in the state of “
LINE
”, press “ON/TARE key to confirm. “0.000” will show, press ON/TARE key again, a few
seconds later half of full capacity weight value will show, put the corresponding calibrating weight on the center of the
platform, then press ON/TARE key, then the full capacity weight value will show, put the corresponding calibrating weight
on the center of the platform, then press ON/TARE key again, meanwhile the full capacity weight value will display,
indicating that calibrating is over and normal weighing can be done.
5.2 Sensitivity calibration
When in state of "
CAP
", press “ON/TARE key to confirm. “0.000” will show, press ON/TARE key again, a few seconds
later the scale displays six digits and the highest digit flashes. Press OFF/MODE key to switch calibration weight and
confirm by ON/TARE key (It is recommended to use over 50% full capacity weight to calibrate) .When the all 6 digits stop
flashing, it means the calibration weight is confirmed. Place the calibration weight on the scale, press ON/TARE key, the
scale displays the calibrated weight, then the calibration completes.
