Manually Converting to CSV Format (Convert WTS to CSV)
You can convert the stored data selected in the file list to ASCII format (.csv). This menu item appears when you
press File List to display the file list.
A CSV file is saved in the same folder as the storage data file you are converting.
• Data storage may fail under the following circumstances. When this happens, an asterisk appears in the
storage state indication. The storage count includes the missing stored data.
• When you perform consecutive operations in the setup menu.
• When this instrument receives consecutive communication commands.
• When you operate this instrument over FTP.
• If a new numeric data storage operation begins before the previous operation is finished, some of the
numeric data may be lost. When this happens, an asterisk appears in the storage state indication. The
storage count includes the missing stored data. You can avoid the loss of numeric data during storage by:
• Setting a longer data update interval.
• Reducing the number of stored data types.
• Using a faster USB memory device.
• When it takes a long time for data to be written to the USB memory device, storage may be stopped
forcefully, and some data may not be saved. When this happens, the storage state indication is “Error.”
• Conversion to ASCII format (.csv) uses a pair of files that consists of a stored numeric data file (.wts) and a
header file (.hds) with the same name. Do not change the names of stored numeric data (.wts) and header
(.hds) files for different sets of data to the same name. If you do so, this instrument may malfunction and
the USB memory may be damaged when you convert the data to ASCII format (.csv).
• If you remove the USB memory during storage and the storage state indication is “Error,” the storage data
file may be incomplete or corrupted. If this is the case, you will not be able to convert the data to ASCII
format (.csv). Be sure to remove the USB memory after storage has been reset or has completed (CMPL).
• Please be aware that the number of times that you can write to USB memory is limited.
