.
If the weighing device is unstable, the sensitivity adjustment will not be executed and the weighing state will automatically shift to the weighing state (0x00000000).
※
3
.
If the value of the weighed sensitivity adjustment weight is not appropriate, a sensitivity adjustment error (0x0006) will occur. After that, it automatically shifts to the weighing
state (0x00000000).
