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 displays 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 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 WEIGHT and TOTAL PRICE window remain the same. Place a
standard weight between 25%-100% FS on the center of the scale, press ENTER 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“0.000”, 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 to confirm.
8. After calibration finishes, 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, and please try to return back to the last step to disposal.
10. Once the calibration switch is changed to OFF, the scale will exit the calibration mode.
Note: Once the ON/OFF EXIT key is pressed, the scale will exit the calibration mode. After the calibration completes, the
scale will re-initialize to be ready for normal weighing.
18. LCD test mode
1. Long press the ON/OFF EXIT+PRINT key, until all segments of LCD are displayed.
2. (a) Press 0 key--- all segments are shown;
(b) Press 1 key --- different segments will be shown;
(c) Press 2 key --- segments on different COMs will be shown;
(d) Press ENTER key ---segments will be shown in turn of above a-b-c steps
3. Press EXIT key --- exit this mode
