• n/16
The maximum number of display data files that can be written to the internal
memory is 16. “16” represents this value.
The value n is the number of display data files in the internal memory.
Note
In the following cases, the display data is overwritten from the oldest file. Use caution
because the overwritten data is lost forever.
• When there is no more remaining time of the display data acquisition area in the internal
memory
At this point, the status display section shows [Overwrite].
• When the number of display data files in the internal memory has exceeded 16
6. Memory usage of the event data acquisition area in the internal memory
Displayed when acquisition of event data is enabled.
• When the acquisition mode is [Free]
• Bar graph
Indicates the amount of event data acquisition area that is being used.
• Time display
Remaining time of the event data acquisition area. When the remaining time
becomes short, the time is displayed in units of minutes.
Remaining time Unit
100 days or more % (Percentage of the remaining area in the event data acquisition area)
100 hours or more to Days (time unit less then one day is truncated)
less than 100 days
60 minutes or more to Hours (time unit less then one hour is truncated)
less than 100 hours
Less than 60 minutes Minutes (time unit less then one minute is truncated)
• n/16
The maximum number of event data files that can be written to the internal
memory is 16. “16” represents this value.
The value n is the number of event data files in the internal memory.
Note
In the following cases, the event data is overwritten from the oldest file. Use caution because
the overwritten data is lost forever.
• When there is no more remaining time of the event data acquisition area in the internal
memory
The status display section shows [Overwrite].
• When the number of event data files in the internal memory has exceeded 16
• When the mode is [Trigger] or [Rotate]
• Bar graph
Displays the acquisition time (amount of memory used with respect to the
data length) of the specified event data.
When pretrigger is specified and START is pressed causing the CX2000 to
enter the trigger wait state, data of size equal to the pretrigger amount is
acquired to the internal memory. At this point the bar is displayed in orange.
After acquiring the data of size equal to the pretrigger, the length of the bar
stays fixed. However, the relevant data is updated until the trigger condition
is met. When the trigger condition is met, the bar turns green. Data is
acquired to the internal memory after the pretrigger data.
If data acquisition to all blocks is finished in [Trigger] mode, [Full] is displayed
in the bar. When [Full] is displayed, event data is not acquired to the internal
memory even if the trigger condition is met.
