Next to each button are descriptions of the file which will be exported to the drive if the corresponding button is pressed.
After pressing the button for the type of file to export the following occurs –
1.
You are prompted to enter the filename of the file to be exported (the extension is automatically provided).
2.
If the file specified already exists you are asked if it is OK to overwrite the file.
3.
For some types of files you are asked for which VPA to export the selected data.
4.
The selected data is then written to the selected file.
The right side of the screen shows the export progress and when completed you may press another button for a further USB
drive activity or press the RETURN button to return to the screen which was being viewed when the USB Drive Info area was
initially pressed.
If the POWER button is pressed while file activity is in progress then the power off is delayed until it is completed.
23.5.1
SCREEN
IMAGE
FILE
(.BMP
EXTENSION)
The image generated is that of the screen which was present when the USB Drive Info Area was first pressed. Many of the screen
images shown in this document were generated in this manner.
This is a standard 16bpp BMP format file (as defined by Microsoft and Adobe) with 800 x 480 pixel size. Most image processing and
viewing programs can open this file format, but it has been found that some photo image software (e.g. Google Picasa) cannot as the
16bbp format is not commonly used for photographs (but is commonly used for graphics images).
Gimp, Adobe Photoshop, Windows Photo Viewer, Paint, and Word are just a few examples of programs which can open these files
(these program names may be trademarks of their respective owners).
These files are quite large (751Kbytes) and are uncompressed images for maximum quality.
23.5.2
BINARY
(.CFG
EXTENSION)
FILES
These types of exported files have a proprietary binary format and are intended to be later imported into a XT2640.
You can have as many files of these types of files on the drive as you wish, so you can have many different configurations, custom
screens or sets of harmonics limits etc. available to the XT2640 in this manner. You can also share these between different users of
XT2640’s, or use them to maintain a record of a configuration used.
23.5.2.1
CONFIGURATION
FILE
The file contains:
All screen configurations.
The custom screen definition.
All measurement configurations.
Any voltage and current harmonics limits defined.
The measurement preference settings.
The file does not contain the power preference setting, the interface configuration or the time and date format configuration settings.
These files are approximately 17K bytes in length.
23.5.2.2
CUSTOM
DATA
SCREEN
DEFINITION
FILE
These files are approximately 12K bytes in length.
23.5.2.3
HARMONIC
LIMITS
FILE
This file contains both voltage and current harmonic limits.
These files are approximately 5K bytes in length.
23.5.3
COMMA
SEPARATED
VALUE
(.CSV
EXTENSION)
FILES
These types of exported files are in the CSV ASCII format and have the .CSV extension in the filename.
These are tabulated files of data suitable for directly importing into many spreadsheet (e.g. Excel™) programs or text editors.
