a)
Stop: The default state, and when the memory is full any active logging will stop.
b)
Overwrite: Allows logging to continue after the memory is full by erasing the oldest sample and
replacing it with the latest.
Note: The three options below must be selected before the times and dates are entered in
Start Time
and Date and Stop Time and Date.
c)
Daily: Activates logging for part of each day as defined by the Start Time and Stop time. When
selected, and the logging is started via the
Set Auto start option, the flow value will be logged each
day between the times specified. The
Stop Time must be later than the Start Time. The data will be
accumulated into a single file.
d)
Weekly: This is similar to Daily in that the active logging period is defined by the Start Time and
Stop Time. The difference is that with Weekly the logging occurs every 7 days, with the start day being
defined by the selected
Start Date.
e)
Monthly: This is similar to Daily in that the active logging period is defined by the Start Time and
Stop Time. The difference is that with Monthly the data is logged on the day of the month specified in
the
Start Date. If this is set to 29, 30 or 31, and the current month does not have this number of days,
logging will occur on the last day of the month.
Note: if you select to clear all logs you will lose all the currently held log data.
