10.3 Saving Setup Parameters, Waveform Display Data, and Numeric Data
File Names and Comments
• You must enter a file name. You do not need to enter a comment.
• You cannot enter a file name if there is another file in the same directory with that
name (no overwriting).
Usable Characters and Maximum String Lengths
Setting Max. Length
File name 1 to 8 characters
Comment 0 to 25 characters
Auto Naming Feature
If you set Auto Naming to ON, the WT500 will automatically assign a four digit number to
the files that it saves, from 0000 to 0999. You can set a common file name to put before
the number (by specifying it in File Name; the name can have up to eight characters).
Selecting Which Files to Display in the File List Dialog Box
You can select which types of files to display in the File List dialog box.
• Item
The only files in the selected directory that appear are those of the type set for the
File Item option in the File menu. If File Item is set to Setup, only files with the .set
extension appear. If File Item is set to Wave or Numeric, only files with the .csv
extension appear.
• All
All of the files in the selected directory appear.
Properties
See "Properties" under "Explanation" in section 10.6.
Note
• For the meanings of the displayed measurement function symbols, see section 2.2,
"Measurement Functions and Measurement Periods"; section 2.5, "Computation"; section 2.6,
"Integration"; and appendix 1, "Symbols and Determination of Measurement Functions."
• You can only select wiring unit Σ when it has been selected according to the procedure
described in section 4.2, "Selecting a Wiring System."
• The maximum harmonic order that can be saved is determined by the maximum harmonic
order set in the harmonic measurement (option) menu.
• File paths can be displayed using up to 41 characters. If a path exceeds 41 characters, an
ellipsis appears at the end of the character string.
• File names are not case-sensitive. Comments are case-sensitive. The following file names
cannot be used due to MS-DOS limitations:
AUX, CON, PRN, NUL, CLOCK, COM1 to COM9, and LPT1 to LPT9
• A directory can contain up to 1000 files. To save more than 1000 files, either start saving to
a different directory, or move already saved files to a different directory.
• If there are a large number of files on a single directory, the amount of time that it takes to
write to and read files becomes longer. If this happens, start saving files to a directory with
less files, or move the files in the save destination to a different directory.
• Because the header files saved by the WT500 use a format that is common to YOKOGAWA
measurement devices, they contain some data that is not used by the WT500.
• The WT500 cannot load setup parameters that have been saved by a product with an
incompatible firmware version.
