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 UNIT/HOLD
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 UNIT/HOLD 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 repeat the procedure from
step3.
