Saving Measured Data and Computed Data
Files can be created for every measurement group. An individual file is created for
computed data. For each measurement group, you can select whether or not to perform
the save operation.
The table below shows the approximate interval over which data can be saved to the CF
card when one measurement interval is used.
Save Channel Measurement Interval Capacity of the CF Card
128 MB 512 MB
10 ch 10 ms 8.8 hours 35.3 hours
100 ms 3.7 days 14.8 days
1 s 37 days 148 days
Saving Thinned Data
Data is saved at a specified thinning interval. Thinning time:
4, 5, 10, 20, or 30 seconds, or 1, 2, 3, 4, 5, 10, 20, or 30 minutes, or 1 hour.
Select a thinning time from the above choices.
Saving Data at Multi Intervals
The recording operation can be specified for each interval group. Multiple sets of data
can be saved simultaneously such as recording an interval around a sudden event while
continuously recording long-term changes in the data.

File Division
You can use the Event/Action function, communication commands, or operations in the
browser’s status information screen to divide the file containing measured, computed, or
thinned data at an arbitrary time. After dividing a file, the next file division is enabled 10
minutes later.
