Appendix 4 Binary File Size Calculation

Appendix
(Byte units)
File size = Header size + Data size
Header size = Text header size + Binary header size
Text header size = 512 × (4 + no. of analog channels × 2 + no. of pulse channels × 2
+ no. of alarm channels × 28)
Binary header size = 512 × (5 + no. of analog channels + no. of pulse channels
+ no. of alarm channels)
Data size = no. of analog channels × 2 + no. of pulse channels × 4
+ no. of alarm channels × 2
You can check an estimate of the remaining time available on the attached CF card/ USB
flash drive on the [Setting] screen.
(About 90% of the time calculated using the above formulas is displayed as the [Avail-
able save time] on the [Setting] screen, reflecting the fact that file and other informa-
tion apart from actual data is also stored on the media.)
