Transmit the present load data reading out
command from the host.
 As for the load value read by the load data
reading out command, the decimal point

Transmit the display value to want to display
now by span fine adjustment command.
According to the return data, proceed to the
following steps.
・When the return data is as same as command.
As the termination is in normal, proceed to the
next step.
・When the return data is “SP−L”
The span fine adjustment range is less than 0.2
mV/V. Set the span fine adjustment range from
0.2 mV/V to 3.1 mV/V.
・When the return data is “SP−H”
The span fine adjustment range exceeds over
3.1 mV/V. Set the span fine adjustment range
from 0.2 mV/V to 3.1 mV/V.
