1. When the calibration switch is ON, turn on the scale, or make the calibration switch ON when the scale
is under the weighing mode, the scale will enter the calibration mode automatically.
2. After entering into the calibration mode, the WEIGHT window will display CAL.ON, which means the
calibration switch is on. The UNIT PRICE window displays “Unit.0” or “Unit.1”, which means the chosen
calibration weighing unit is kg(Unit.0) or lb(Unit.1), the TOTAL PRICE window displays empty.
3. Use Unit key to choose the calibration weighing unit kg or lb (the corresponding unit indicator will be
lightened on), use ENTER key to confirm the unit and go to the next step.
4. The WEIGHT window still displays CAL.ON, UNIT PRICE window displays “unLoAd” (this means that the
scale is ready to calibrate the zero point position, please remove any weight on the scale), the TOTAL
PRICE window display the output inner code of A/D. When the scale is stable and the unit indicator
stops flashing, press ENTER key to confirm the zero point calibration. After the scale is stable and gets
the zero point, the scale will go to the next step automatically.
5. The display of the WEIGHT window remains the same, the UNIT PRICE window displays “LoAd”, which
means the scale is ready to calibrate the standard weight. The display of the TOTAL PRICE and WEIGHT
window remain the same. Place a standard weight between 25%-100% FS on the center of the scale,
press ENTER key to confirm the standard weight calibration after the scale is stable and the unit
indicator stops flashing. When the scale gets the stable data, it will go to the next step automatically.
6. The display of the WEIGHT window remains the same, the UNIT PRICE window displays “InP.Ld”（Input
Load Weight, the TOTAL PRICE window displays 0, use 0-9 numerical key or CLEAR to input loaded
standard weight, then press ENTER key for confirmation, the input data will be shown on the total
quantity window, and then please remove any weight on the scale.
7. When the WEIGHT window displays “unLoAd” again, the scale is ready to re-confirm the zero point,
remove any weight on the scale, after the scale is ready and unit indicator stops flashing, press Enter key
to confirm.
8. After the calibration completes, the UNIT PRICE window displays “CAL.END” and TOTAL PRICE window
displays current weight.
9. If there’s an error occurred in calibration, the scale will display CAL.ERR, It usually means incorrect data
input or loading weight.
10. Once the calibration switch is changed to OFF; the scale will exit the calibration mode.
The calibration switch is located underneath the
scale base. When the switch is set towards the
USB or RS232 interface, it means CAL switch is
on. When the switch is set towards the power
switch, it means the CAL switch is off.
