WCA230A & WCA280A User Manual
The number of frames ValidFrames (refer to page 3--254) is not known at the
time the program creates the file header, so the internal program temporarily
writes ValidFrames=0. If the value of ValidFrames of the file header is 0,
examine the file size and calculate the true value of ValidFrames. In this case, the
correction data block, the dummy header, and the extended correction data block
are always added.
The subsections below provide details on each block.
The following is an example of the file header. Although Type is always written
at the beginning, the order of the other items is not fixed and some new items
may be added.

not WCA280AIQT but WCA380IQT)

The first character “4” indicates that the number of bytes of the file header is
expressed with four characters after the second character.
In the preceding example:
Number of bytes of the file header = 1 + 4 + 0416 = 421
The number of bytes is therefore 421. Data starts from the 422
nd
byte.
