Automatic logging modes
Autolog mode:
SunScan can be logged automatically from the
PDA via the SunData Utilities, Auto log function.
With Autolog you can operate SunScan
automatically in any of its modes, just as if you
were pushing the read, store and average buttons
at regular intervals.
See also : Appendix A. Logging the probe as a
Linear Quantum Sensor on page 74.
Tap on a date field to
change it
Night time is defined as
when the sun is more than
6° below the horizon.
Sunscan computes this for
you automatically.
The Start time can be set to a time up to 24 hours before the current time!
You might do this, say, if you wanted to set up averaging on the hour with
sampling every minute but the system
time had just gone past the hour.
Start Logging
Selecting Start logging displays a
summary of the logging progress as
shown.
Selecting Sleep puts the PDA into a low
power state between readings.
