Schedule Sampling
allows you to select a logarithmic style sampling schedule adapted to the needs of each
application.
Schedule Sampling is set by using the plus and minus buttons to add or subtract line items in the Schedule
window. The maximum number of line items in a schedule is 30, each with its own sampling Interval of
seconds, minutes or hours and duration of seconds, minutes, hours, days or weeks. A Pause interval can also
be selected, which stops the Levelogger from recording for the specified Duration.
Running totals of the number of readings still available, and the run time to date are shown. If the number of
readings selected exceeds the Levelogger’s memory capacity, an error message appears.
By checking Repeat, the Levelogger will continue to run through the schedule until its memory is full, or it
is stopped.

5.6 Datalogger Memory Mode
Datalogger Memory Mode selection will only appear when
Linear
sampling mode is selected. When in
Linear Mode, there is a choice of
Continuous
Logging (wrap around)
or
Slate
Logging
.
Event Based and Schedule sampling modes can only use the Slate Mode option.
In Continuous Logging, the new log is started at the end of any previous log and continues logging, eventually
recording over the first logged data. As one of the download options is to ‘Append Data’, Continuous
Logging can be a preferred choice when logging long-term (see Section 7.1.2).
In Slate Logging, the new log is also started at the end of any previous log, but will stop recording after the
dataloggers memory is full (e.g. 150,000 sets of readings), so that the beginning of the current log will not
be written over.
