Pretrigger function: The pretrigger when the recording start action is set to Trigger can
be set for each interval group from 0 to 100% in 10% intervals.
Pretrigger length: When there are fewer than ten data, the
pretrigger length is rounded up.
When there are ten or more data, the
pretrigger length is rounded down.
Ex.) Recording interval 600 second, data length 1 hour,
pritrigger 30 %
Number of data in a file: 1 hour / 600 s = 6
Pritrigger length = 6 × 30 / 100 = 1.8 about 2 files
Posttriger length = 6 - 2 = 4
Recording channels: You can select to record or not record for each channel. However,
the number of recording channels is limited as follows:
No. of recording channels per unit of time:
1500 ch/s (when not using the report or manual sample function)
1200 ch/s (when using the report or manual sample function)
Ex.) Measurement group 1 Recording interval 10 ms, 10 ch
Measurement group 2 Recording interval 100 ms, 50 ch
(1 s / 0.01 s) × 10 ch + (1 s / 0.1 s) × 50 ch = 1500 ch/s.
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.
File name: Automatically generated using the date and serial number
mddinnnn.MXD
m: Month file created (local time), 1 to 9, X (October),
Y (November), Z (December)
dd: Date when file created (local time), 1 to 31
i: Files for measurement groups 1 to 3 are 1 to 3
Computed data files are M
Thinned data files are T
nnnn: Serial number (0000 to 9999)
MXD: File extension (uppercase)
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.
