Appendix 5 Binary File Size Calculation
(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 × 3 + no. of pulse channels × 3 + no.
of logic bits × 3 + no. of alarm channels × 3 + no. of waveform calcula-
tions × 3)
Binary header
size =
512 × (12 + no. of analog channels × 3 + no. of pulse channels × 3 + no.
of logic bits × 1 + no. of alarm channels × 20 + no. of waveform calcula-
tions × 3)
Data size = (no. of analog channels × 2 + no. of pulse channels × 4 + no. of logic
channels × 2 + no. of alarm channels × 58 + no. of waveform calcula-
tions × 8) × no. of data points
Notes
The no. of logic channels can be either 0, or 1 when using logic.
The no. of logic bits can be 0 to 8.
The no. of alarm channels can be either 0, or 1 when using alarms.
You can check an estimate of the remaining time available on the attached CF card/ USB
flash drive on the [Setting] screen.
