Saving and Loading Data
13
Property
Displays the following information about the selected file: filename.extension, the file
size, the date/time the file was saved, the attribute, the comment, the presence of voice
memo, the module configuration when the file was saved, the conditions for saving, etc.
Note
• An error occurs, if a key other than the Abort key is pressed while saving or loading a file.
• Saving and Loading is not possible while data acquisition is in progress.
If waveform data is loaded, the accumulate setting is always turned OFF.
• If you change the extension of the saved data such as on a PC, the file can no longer be
loaded.
• Up to 36 characters can be displayed in “Path.”
• File names are not case-sensitive. Comments are case-sensitive. In addition, the
following five file names cannot be used due to limitations of MS-DOS.
AUX, CON, PRN, NUL, CLOCK, COM1 to COM9, and LPT1 to LPT9
• The waveform data loaded from a file overwrites the data in the acquisition memory.
Once the memory is overwritten, the old data cannot be recovered. It is recommended
that the current waveform data be saved before loading data from a file.
• If the total number of files and directories exceed 5000 in a single directory, the file list is
no longer displayed.
• This function cannot be used when using the FTP server function, network printer function,
or the Web server function.
• Waveform (.wvf) and header (.hdr) files are saved as file pairs. If you specify “*.*” for the
files to be displayed (Filter) on the File List and manipulate individual files (Delete,
Rename, or Copy), the file can no longer be loaded.
• Files that do not have an archive attribute are not displayed in the File List window. Do not
remove the archive attribute of the files saved by the DL750/DL750P using your PC.
Data Format When Storing Multiple Records
When multiple records are stored (history memory, for example), the following data
format is used.
ASCII Format: CR+LF is inserted between records.
<Header>
Measured data 1-1 of CH1, Measured data 1-1 of CH2, Measured data 1-1 of CH3, ... , [ CR+LF]
Measured data 1-2 of CH1, Measured data 1-2 of CH2, Measured data 1-2 of CH3, ... , [ CR+LF]
Measured data 1-m of CH1, Measured data 1-m of CH2, Measured data 1-m of CH3, ... , [ CR+LF]
[ CR+LF]
Measured data 2-1 of CH1, Measured data 2-1 of CH2, Measured data 2-1 of CH3, ... , [ CR+LF]
Measured data 2-2 of CH1, Measured data 2-2 of CH2, Measured data 2-2 of CH3, ... , [ CR+LF]
Measured data 2-n of CH1, Measured data 2-n of CH2, Measured data 2-n of CH3, [ CR+LF]
[ CR+LF]
Record 1
Record 2
Float Format: Stored in blocks of channels.
Measured data of record 1 of CH1
Measured data of record 2 of CH1
Measured data of record N of CH1
Measured data of record 1 of CH2
Measured data of record 2 of CH2
Measured data of record N of CH2
