2. Select if “Moon data” is to be computed and logged.
3. Select “Freshness” to identify Fresh/Stale results. This is useful when recording brightness from a moving platform,
specifically.
4. Select “Single .dat file” to prevent separate daily files being created each 24 hours.

6. Select “Raw frequency” when the rFx command is desired which send the linear raw light reading frequency.
(Firmaware 75 and above).

Threshold to record A threshold for recording readings can be set before starting recording. Any reading greater or
equal to this threshold value will be recorded in the log file.
Figure 7.27: Log Continuously Threshold
A threshold of 0 will allow all readings to be recorded.
The threshold indicator will turn green if the threshold of the triggered reading is met (recording) and red if the
triggered reading is below the threshold (no recording).
The threshold value is saved in the registry configuration file when it is changed. Changes can only be made while not
recording.
An override from the command line options (-LCTH,x) can be made. The override will only take effect for the current
session and will not alter the saved configuration.
Pre-reading audio alert In cases where you want to be alerted that a reading will be taken, for example, when manually
pointing the meter, the Pre-reading audio alert (Fig. 7.28) can be enabled to play an audio file two seconds before the
record is logged. The Test button plays this file for test purposes. The audio file is named
prereading.wav
and is located
in the Data Directory (which can be identified from the main page
