Event data are recordings of instantaneous values at each measurement interval.
Display data are recordings of the maximum and minimum values of the data sampled within the display update time.
 See "Display Data Files and Event Data Files." |
Display data
　Measured data: 4 bytes/data; computed data: 8 bytes/data
Event data
　Measured data: 2 bytes/data; computed data: 4 bytes/data |
This is because display data is indicated for the data format.
The maximum and minimum values of the multiple data measured in the measurement interval within the sampling interval are saved as display data.
See "Display Data Files and Event Data Files." |
With display data, the fastest (shortest) data save interval is 0.5 seconds (when the waveform update interval is set to 15 sec./div).
If you wish to save the 125 msec interval data, save it as event data.
See "Display Data Files and Event Data Files." |
To change the data save interval of display data, change the display update interval.
Note that the unit of the display update interval is "/div," and 30 data are saved per div.
Thus, when the display update interval is 30 min/div, the sampling interval becomes 30/30 = 1 min.
See "Display Data Files and Event Data Files." |
| Set the auto save interval to 1 day, then set the memory time up to the 0 hour under Day. |
| The items that can be set are assigned to soft keys based on the display update interval, number of data save channels, and other parameters.
To make a setting of 31 days available, you must enter setup mode and decrease the number of data save channels or lengthen the data update interval. |
| Data is recorded from the pressing of the START button to one day thereafter.
However, when used together with the memory time up function, the file can be divided, for example, at the 0 hour, and one day's worth of data can be recorded thereafter. In this case, a file is created every day at the 0 hour, resulting in recorded files of a determined time span. |
When recording only display data: up to 100,000.
When recording only event data: up to 120,000.
When creating both display and event data files at the same time: up to 75,000 display data, and up to 30,000 event data. |
Yes. You can use the Historical function.
You can perform a "Historical display" of display data in the internal memory or external medium. |
| Data acquired on the DX is in binary, and cannot be viewed as-is on the PC.
Dedicated software (DAQSTANDARD) is required to view the contents. |
Event data are the instantaneous values of each sampling interval.
Event data can be saved at shorter intervals than display data, making them useful for performing more detailed analyses. |
In E+D mode, the event recording function does not enable continuous triggered recording. The trigger settings are probably incorrect.
Please check the trigger settings entered in SETUP mode.
