9. Cal.p1 will be displayed. This is the second calibration point. The default
standard weight is 50% of full scale. Load weight from 12.5% to 100% of full
scale.
10. Use the [PRINT/HOLD] and [UNIT] keys to input the loaded weight.
10a. If the input data is larger than 199999 it will be shown by first four digits and
last four digits: Hxxx and Lxxx.
10b. If the triangular symbol on the left bottom of LCD window appears, it means
that the digit being changed is the displayed most significant bit which can only
be 0/blank or 1.
11. Press the [TARE] key to confirm your setting and the indicator will flash the
input standard weight. Wait till the scale comes steady and input A/D data as
per the standard weight.
12. Cal.p2 will be displayed. This is the third calibation point. When xxxxxx kg (or
lb) is displayed (100% FS is default), you can press [ON/OFF/ZERO] to exit
the calibration mode or place a standard weight (must be in the range of 25%-
100% FS, and equal or larger than that for the second calibration point; this is
also the range of your input number) on the scale.
13. Use the [PRINT/HOLD] and [UNIT] keys to input the loaded weight.
14. Use [TARE] key to confirm the standard weight and input number are correct.
14a. If the calibration weight for third point is same with that for second point and
the calibration weight is more than 25%FS, input the standard calibration
weight same as second point calibration and press [TARE] key to confirm the
setting. The indicator will flash the input weight. If the indicator get reasonable
data (the input weight is correct, and the calibration weight of third calibration
is more than equal to the calibration weight of second calibration), it will go to
next step.
15. Cal.p0 will be displayed again. Press [TARE]. The display will blink. If the
calibration is good the data will be saved. The display will perform an auto
reset and return to the working mode.
15a. If an error occurs during calibration, cal.er will be displayed. Start from step
1 and recalibrate.
5.2 Display ADC Code or Working Voltage Value
In this mode, you can examine the stability of weighing system and increment the ADC
output code corresponding to the loaded weight.
Note:
l
The increment of ADC code for full scale weight must be larger or equal to 2
times of selected display division. Otherwise, the calibration cannot be
properly completed.
m
e.g. The display division is 0.1kg. Load 100kg standard weight on the
platform, the increment of ADC code should be at least more than
2x100kg/0.1kg= 2x1000=2000. In this case, the scale can be calibrated.
Otherwise, smaller division needs to be chosen.
l
The data should be stable. Otherwise, the calibration cannot be properly
completed.
