5. Data Processing
Certain adjustment items require the microprocessor data to be read out or the displayed data (hexadecimal numbers) on jigs or adjusting
remote commander to be calculated to get adjustment data. In such a case, convert hexadecimal numbers into decimal numbers once, then
make calculation, and convert its result into hexadecimal number as adjustment data. Table 1 shows hexadecimal – decimal number
