Settings and Measurement
CHECKPOINT
Changing the sampling interval, capture destination, or number of capture
points will change the screen display of the time available for data capture,
capacity available for data capture, and possible number of times of repeating.
If you find that the measuring time exceeds the capacity available for data
capture, either change the sampling interval or capture destination (to large-
capacity USB memory).
Time available for data capture ................. Indicates how long data can be
captured.
Capacity available for data capture ........... Indicates the capacity available for data capture with the
memory size if the data capture destination is the internal
flash memory or USB memory. The figure shown in
brackets is the percentage of free memory space to the total
memory size.
Possible number of times of repeating ...... Indicates how many times data captured to the internal RAM
can be saved to the save destination device if Auto Save is
set to On. Beware of using this setting particularly when
Repeated Capturing is set to On for the trigger (For details,
see page 3-26 in the "TRIG Settings."
