DATA LOGGING
Data logging is an optional extra. A standard unit can be upgraded to include data
logging by returning it to the manufacturer. If data logging is not fitted then the
relevant menu items are not displayed.
If data logging is fitted “Data logging” is one of the options when the Set button is
pushed.
Wrap Data
If Wrap is set (press Set\Data logging\Wrap) then logging continues when the logger
memory is full overwriting the oldest data.
If No wrap is selected (press Set\Data logging\No wrap) logging stops when the
memory is full.
Show Status
To see how much data has been saved, when logging was started etc select
Set\Data logging\Show status and the information is shown on the screen for 20
seconds. Press the X button to clear the screen sooner.
Start Logging
To start logging press Set\Data logging\Start and then select the log period and press
Set again.
If logging is started then any previously logged data is lost, so be sure that saved data
has been transferred before starting again.
The Log Period is how often readings are taken, if the log period is short then it will
be less time until memory space runs out. The storage capacity is 10,900 readings of
all 4 parameters (UV, Visible light, temperature and humidity). The other values
(e.g. dewpoint and µW/Lumen) are calculated from the 4 saved parameters.
Logging commences at a time so that measurements are taken at the start of each
minute, 10 minutes, hour etc.
Log Period Max Log time (Days, Hours:Mins) Logging Commences
10 seconds 1, 6:16 Start of next minute

Logging will continue until the memory is full or a low battery condition is detected.
