Recording interval: Set the recording interval for each measurement group as a
multiple of the measurement interval.
For a measurement interval of 50 ms, 500 ms, or 5 s, set a
multiple of 1, 2, 4, or 10.
For other measurement intervals, set a multiple of 1, 2, 5, or 10.
Otherwise, set a multiple of 1, 2, 5, or 10.

Data length: Measurement groups for which TRIGGER was selected can be
set individually.
For the measurement groups on which Direct mode was selected,
all groups have the same length.

File size: Within approximately 10 Mbyte per fi le
File size calculation: File size (bytes) = header size* + data size **
* Header size (bytes) = 904 + no. of recording channels × 232
** Measurement data size (bytes) = no. of recording measurement
channels × 4 × no. of samples
Math data size (bytes) = no. of recording math channels × 6 × no. of
samples
No. of samples = Data length (s)/recording interval (s)
Ex.) Recording interval: 100 ms; no. of measurement channels, 24; data
length, 10 min.:
Header size = 904 (bytes) + 24 × 232 (bytes) = 6472 (bytes)
Data size = 24 (bytes) × (600 (s)/0.1 (s)) = 576,000 (bytes)
File size = 6472 + 576000 = 582472
≈ 56.8 Kbyte
