4. Calibration

Note:

(1) Before calibrating the scale, you should prepare standard weights (more than 10% of FS weight) for

calibration.

(2) In the following steps, pressing ZERO/ON/OFF will exit calibration.

1. Move all weight from the scale. Under normal weighing mode, press and hold TARE and ZERO/ON/OFF keys for

more than 4s to enter calibration mode.

2. The indicator will show “CAL-?”, which means the scale is ready for calibration. Press the TARE key to confirm

and continue into calibration mode.

3. When “CAL.P0” is displayed, the scale will begin to calibrate the zero-point of the scale. Remove all weight from

the scale. Press the TARE key to confirm, or press the ZERO/ON/OFF to exit this mode. After receiving the

reasonable zero-point data, the next step will automatically occur.

4. When “CAL.P1” is displayed, the scale will be calibrated on second calibration point. xxxxxx kg (or lb) will be

displayed. The default standard weight is 50%FS. Load 5%-100%FS weight on the scale, and use the HOLD or

UNIT keys to input the loaded weight. Press the TARE key to confirm the input, and then the indicator will flash the

input standard weight. After the scale becomes stable and receives the ADC’s data corresponding to the standard

weights, and if the data is reasonable and acceptable, the indicator will automatically be directed to next step. If the

second point cannot be calibrated correctly, it will display “CAL.Er” and return back to step3 for re-calibration.

5. When “CAL.P2”is displayed, the scale will be calibrated on third calibration point. xxxxxx kg (or lb) will be

displayed. The default standard weight is 100% FS. Load 10%-100%FS (this must be equal or larger than the

weight from the second calibration point) weight on the scale. Use the HOLD or UNIT keys to input the standard

weight’s value. Press the TARE key to confirm. The indicator will flash the input weight. If the indicator receives

reasonable data, it will go to next step automatically. If an error occurred, the scale will display “CAL.Er” and

return back to step3 for re-calibration.

6. When “

CAL.P0” is shown again, the scale will calibrate the zero-point again. Remove any weight from the scale,

press the TARE key to confirm; the displayed data will flash. If the indicator receives reasonable data, it will

calculate and store all parameters into EEPROM. Then it will auto-reset, and be directed to weighing mode. If an

error occurred in calibration, the scale will display “

CAL.Er” and then it necessary to repeart the procedure from

step3.
