Execution conditions for these
commands

12-1-12. Read Decimal Point Position for Display

Write UUID E812 handle (Hex) with the following command(s):
Calibration Command (Hex)
99
After the above 'Read' command set is successfully written to the UUID E812 handle, there will be
return values (Hex data) after reading the UUID E812 handle, such as the following:
99 02 06 GG
GG: 1-byte decimal point position for display; please refer to 12-1-11 Write Decimal Point Position for
Display.
If the 'Write' operation has failed, reading UUID E812 handle will instead return 99 02 7F .... (please
refer to 12-1-39 Return Read & Write Status)

12-1-13. Write Linearity Calibration

This 47(Hex) sub-command set can be written only when Calibration Mode is enabled.
Write UUID E812 handle (Hex) with the following command(s):
Calibration Length Sub-Command
Command (Hex) (Hex)
(Hex)
99 0B 47
Read UUID E812 handle, which will return 99 02 7F .... (please refer to 12-1-39 Return Read & Write
Status).
Example : We want to calibrate empty load, 1/2 full capacity load, and full capacity load. Therefore
TT = 3, NN = 1,2,3; "NN = 1" denotes empty load; and so on...
Suppose empty load Read 's AD value after filtering = 2000 (regarding acquisition of AD value after
filtering, please refer to 12-1-1. Temporarily Switch E813 Notify Output Formats):
1/2 of full capacity load Read 's AD value after filtering = 102000
Full capacity load Read 's AD value after filtering = 202000
