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.
