IntervalAllows the logging interval to be adjusted from 1 to
120 minutes.
Clear Used to erase any data saved within the internal memory.
A statistical summary of the logger’s operating condition is shown at
the bottom of the screen. It is used to identify the number of
records saved in the memory, the remaining logging time available
(days, hours, minutes) before oldest data will be overwritten and also
the percentage of occupied memory space.
Once the memory becomes full of data, the logger will automatically
overwrite the oldest data records with new ones. This ensures the
most recent conditions are always being recorded.
