5.2 Main Module Specifications
Recording of Measured/Computed Values
Measured and computed values can be saved by measurement group to the CF card.
Supported external media:
CF card Type I × 1 slot (Type I can be used)
Max. card size: 2 GB
Supported fi le systems: FAT12 and FAT16
Record start/stop: Starts and stops recording to CF card per the START and STOP
keys, Event/Action function, communication commands, or
monitor screen operation.
Recording stop action: Single, Full Stop, Rotate
Single: Creates a single fi le of a specifi ed size on the CF card
and stops the recording.
Fullstop: Creates fi les of a specifi ed size until the CF card is full
and stops the recording.
Rotate: Creates fi les of a specifi ed size until the CF card is full
and continues the recording by deleting the oldest fi le
in the folder.
The recording stop action can be specifi ed for each interval
group.
If free space cannot be secured or when securing of free space
takes extended time, an error is indicated on the 7-segment LED.
For details, see chapter 4.1, “Media Related Errors.”
Trigger ( recording start action):
OFF, Direct, and Trigger
Direct: Starts recording when recording start is executed.
Trigger: Enters the trigger wait mode when recording start is
executed. Recording starts when an event occurs.
The recording start action can be specifi ed for each interval
group.
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 fi le: 1 hour / 600 sec = 6
Pritrigger length = 6 × 30 / 100 = 1.8 about 2 fi les
Posttriger length = 6 - 2 = 4
Recording channels: You can specify, common to all measurement groups, whether
to record on each channel. However, the number of recording
channels is limited by the measurement interval as follows:
1500 ch/sec. or less
Ex.) Measurement group 1 Recording interval 10 ms, 10 ch
Measurement group 2 Recording interval 100 ms, 50 ch
(1s / 0.01s) × 10ch + (1s / 0.1s) × 50ch = 1500 ch/sec.
