Operations after SD memory card replacement
If the SD memory card was replaced while data logging was running based on the data logging setting file contained in the SD
memory card, the data logging setting file contained in the new SD memory card is used when data logging is started by one
of the following operations. If the new SD memory card does not contain the data logging setting file, data logging is not
started.
• STOP to RUN state
• Power-on to RUN state
• RESET to RUN state
• Data logging start
Stack file remaining in the replaced SD memory card
Replacing an SD memory card that contains a stack file may result in the storage file remaining in the replaced SD memory
card along with storage files. If the stack file is remaining in the replaced SD memory card, recover the latest data contained in
the stack file by doing the following:
• Retrieve the data from the stack file and combine the data with a storage file.
• Save the stack file as a storage file.
