Saving Data Using the Soft Key Menu That Appears by Pressing the [FUNC] Key
If you press the [FUNC] key when [Save] under [Memory] is set to [Auto] and the
acquisition of the display data to the internal memory is started, [Save Display] appears
in the soft key menu. If you press the [FUNC] key when the acquisition of event data to
the internal memory is started in the free mode, [Save Event] appears in the soft key
menu. Press these soft keys at any time to store the display data or event data to the
external storage medium. For the operation of the [FUNC] key, see page 3-6.
Collectively Saving Data When Data Acquisition to the Internal Memory Is Stopped
MENU key (switch to setting mode(control)) > MENU key (switch to Set mode) #5 soft
key (select [Save/Load,Clear data]) > #3 soft key (select [Save data])
Note
• If the memory is full or the number of files exceeds 16, the newest data overwrites the
oldest data file.
• If a power failure occurs, the file is closed. After the power recovers, a new file is created
and data is written there.
• The start/stop operation of the acquisition to the internal memory also starts/stops the
report function (on models with the computation function option /M1).
• If the computation is stopped, you can start the computation by starting the acquisition to
the internal memory.
• When you stop the acquisition to the internal memory, data is saved to the external
storage medium. If the external storage medium is not inserted at this point, an error
message “Media has not been inserted” appears.
• You cannot perform the operation of “collectively saving data when data acquisition to the
internal memory is stopped” if computation is in progress.
• The procedure for saving all data collectively can only be performed when data acquisition
to internal memory is stopped.
Setup Items
Setting the Memory (Acquisition to the Internal Memory and Storage to the
External Storage Medium)
• Save
Select the mode used to save the data in the internal memory to the external storage
medium from [Auto] and [Manual].
• Manual
When you insert an external storage medium into the drive and close the operation
cover, a message “Do you want to save measured data?” appears. Select [Yes]
and press the
[DISP/ENTER] key to save the data.
In manual save mode, set how the data is to be saved, [Unsave] (save only the
data that has not been saved) or [All] (save all the data) at [Trend/Save
interval,Message,File,User key,DST] setting display > [Save data] (see page 9-6).
• Auto
By having the external storage medium inserted in the drive at all times, data save
operation is automatically carried out at specified intervals.
• Data
Select the type of data to be acquired to the internal memory from [Display] (display
data only), [E+D] (display data and event data), and [Event] (event data only).
• Event (only when [Data] is set to [E+D] or [Event])
• Sample rate
Select the interval used to save the event data from the following.
1s, 2s, 5s, 10s, 30s, 60s, 120s, 300s, and 600s
• Mode
Select the mode from [Free], [Trigger], and [Rotate]. [Free] appears as a choice
only when [Data] is set to [Event]. When set to [Free], the following parameters
[Block], [Data length], [Pre-trigger], and [Trigger] are not available.
