DATA PROCESS
In some adjustment items, the calculation of SEUS displayed data
(hexadecimal) is needed to check the specified data or to acquire
the adjustment data. In such a case, prepare a computer capable of
calculating hexadecimal numbers.
Also, the data at two addresses are read, which are treated as 2
bytes of upper 1 byte and lower 1 byte (4-digit hex. number), to
check the specified data.
