11.1 Saving Measured and Computed Data
Procedure for Saving Data
When saving measured/computed data on a floppy disk, save them first on the DR recorder's
built-in RAM disk and then copy them to the floppy disk. You can save the data on the built-in
RAM disk in three ways, as summarized in the following table:
Menu Item
Method for Starting Saving
Number of Files Saved
DIRECT
Immediately starts saving when the setting is complete.
One
TRIGGER
Starts saving when an event occurs as set using the
One
event/action functions.
REPEAT
Starts saving when an event occurs as set using the
More than one*
event/action functions.
* The DR recorder continues to save an array of files of the specified size until the built-in RAM disk
becomes full.

The following paragraphs show the flow operation for a case where a measured data file is saved
using the occurrence of an alarm as a trigger.
