The Autolog function
You can set up the SunScan system to operate automatically in any of its modes, just
as if you were pushing the read, store and average buttons at regular intervals.
Note: don't confuse Autolog with logging the probe as a Linear Quantum sensor, or
with logging the Beam Fraction sensor as an independent sensor. These applications
are dealt with in the Appendices.
From
Menu, Utils, Autolog, Enter
you will arrive in the
Automatic Logging
setup
screen:
The
Start
time can be set to a time up to 24 hours
before
the current time! You might
do this for example if you wanted to set up averaging on the hour with sampling at
one minute intervals but the system time had just gone past the hour.
When you are satisfied with your choices, press
Enter
to accept the screen and
initiate the logging process. After a few minutes the Workabout will sleep and the
screen will go blank. You can safely press
Off
to blank the screen immediately (it
will not stop the Autolog process). From time to time when a reading is logged, the
screen will briefly show a
Logging in progress
message.
At any time, if you want to check the status of the Autolog, press
On/Esc
to access
the screen on the left.
The timing of the next reading (and the Plot and Sample number) will be indicated,
with the current system time. You can either select
Sleep, Enter
(to continue) or
Cancel, Enter
to cancel (stop) the logging session from this screen. If you select
Cancel
you must confirm that you want to stop logging by pressing
On/Esc
.
System time in the heading is
constantly updated
You will be prompted with a current
Start time, and 6 hours later Stop time
and date. Edit these appropriately.
Change the read interval to
whatever sampling interval you
want (hh:mm:ss).
If you leave the Average interval at 0
you will not get average summaries.
Any other setting (hh:mm:ss) will
insert average summaries into the data
file at the specified intervals.
Nighttime is defined as when the
sun is more than 6
°°°°
below the
horizon. SunScan computes this
for you automatically.
This is the Autolog setup screen.
