Measurement can also be stopped with a trigger.
See “Stop triggers” (p. 84).
If you select [Specified time] , the maximum time and data count will be displayed. The maximum amount of
time that you can record varies with the number of channels in use and the recording interval.
If you select [Continuous] , measurement will continue while deleting past data from the internal buffer
memory if the maximum capacity of the internal buffer memory is exceeded. It is recommended to use auto
saving since deleted data cannot be restored.
See “Auto save (real-time save)” (p. 106 ).

Under [Alarm source] , choose whether to record the alarm source channel during alarms.
Set to
[ON]
when you’re using an alarm and you wish to save data for the alarm source channel.
Set as necessary as the amount of data will increase.

When the recording time is set to [Specified time] and repeat recording is set to

Internal processing will take some time (downtime) between the time that recording stops after the
specified amount of time has elapsed and the start of the next recording operation. Recording is not
performed during this time.
Recording
Downtime
You can record without any downtime by setting the recording time to [Continuous] and enabling
auto saving and file segmentation. Saved data files can be segmented using the desired time
segment.
