Saving and Loading the Data
12
• For harmonic measurement mode
• The data in the range from Total or dc (0th order) up to 500th order of the
selected elements and measurement functions are saved.
• Select the element from [Element1], [Element2], [Element3], and [Element4].
• Select the measurement function from U, I, P, S, Q,
λ
,
φ
,
φ
U,
φ
I, Z, Rs, Xs,
Rp, Xp, Torque
*
, and
Σ
List (all
Σ
functions).
*
This is applicable to products (PZ4000) with firmware version 2.01 or later when the
motor module is installed in the element number 4 slot.
• The numerical data of the measurement functions, fU (or fI), Uthd, Ithd, Pthd,
Uthf, Ithf, Utif, Itif, hvf, and hcf, are saved regardless of the selection made in the
previous section.
Selecting the medium and directory
See the explanation given in “Selecting the medium and directory” in section 12.5.
File name and comment
See the explanation given in “File name and comment” in section 12.5.
Auto naming function

Specifying the file to be displayed in the File List dialog box
You can specify the type of files to display.
• Item
Displays only the numerical data files.
• All
Displays all the files on the medium.
Properties
See the explanation given in “Properties” in section 12.5.
Note
•
You cannot save or load while the data acquisition is in progress (START/STOP indicator is
ON).
•
For the meanings of the measurement function symbols, see section 1.2, “Measurement
Modes and Measurement/Computation Periods,” 1.7 “Numerical Computation,” appendix 2
“Symbols and Determination of Measurement Functions,” and appendix 3 “Determination of
Delta Functions.”
•
For details regarding the wiring methods, A and B, see section 5.2, “Selecting the Wiring
Method.”
•
In the places where a measurement function is not selected or where there is no numerical
data, the following data are saved:
•
For ASCII files: A character string “NAN.”
•
For Float files: 0x7FC00000
•
If you change the file extension on a PC, for an example, you will not be able to load that file.
•
A maximum of 36 characters can be displayed in [Path].
•
For file names, upper and lower case letters are not distinguished. For comments, they are
distinguished. In addition, the following file names cannot be used due to limitations of MS-
DOS.
AUX, CON, PRN, NUL, CLOCK
•
When using the GP-IB or serial interface commands to enter a file name, the following
symbols that do not exist on the keyboard of this instrument can be used.
