Reading/Writing Measurement Data
Data Transfer Format
IEEE 64-bit floating point format (Form 3)
With this format, each number is expressed with eight bytes. Therefore, data containing
201 measured values is 3,216 bytes long (2 pieces of data per measurement point).
Numbers are transferred in the format shown in
Figure 6-4.
Figure 6-4 IEEE 64-bit Floating Point Data Transfer Format
MS-DOS personal computer format (Form 5)
This format is identical to the IEEE 32-bit floating point format except that data bytes are
arranged in the reverse order. You do not need to reformat your data as you manipulate it
on a personal computer in the DOS environment.
