● If ring capture is On, the backup function is not available.
● It takes a time for writing after capturing was stopped when many channels are captured, when interval
sampling is fast, when backup interval is long, because the backup data size becomes large.
● Sometimes the backup will be failed when the backup data is saved to the FTP server via the wireless LAN
by condition of Wifi communication.
● When the sampling interval is faster than the 100 ms the backup of CSV format is not able to perform.
● When the capture in CSV format and backup function are enabled, SD CARD replacement for capturing
and Relay capturing cannot be performed.
● When the external sampling function is ON the backup function is not able to perform.
● The media cannot be replaced when saving to an FTP server.
● When using trigger repeat, the repeat interval may become long because the next capturing is started
after the backup writing is completed.
