Three new icons will appear inside the left toolbar:
Settings, Instruments

Log

10.2. Settings
To control basic logger functionality, click on the Settings icon:
One of the most important settings is the
Scan Rate
. This defines how often the logger
scans (samples) its inputs. Faster scan rates make it more likely the data logger will capture
accurate minimum and maximum but will shorten the battery life.
The scan rate also influences averaging. If you want to log average data every 15 minutes,
then a 5 second scan rate implies 15min × 60sec ÷ 5 = 180 samples. If you don’t need that
many samples, you could increase the scan rate to maximise battery life.
Another limit the scan rate imposes is on the maximum logging interval. The maximum log
interval is 65535 times the scan rate. For example, if you set the scan rate to 1 second, the
maximum logging interval is 65535 seconds, or 18 hours 12 minutes 15 seconds. If you
want a log interval of 1 day, you will need a scan rate of at least 2 seconds.
The
Scheme Description
should be set to something that will assist you in remembering
what the scheme is for.
Apart from the
Scan Rate
, the
Communication
settings are the next most critical. If they’re
wrong, you won’t be able to program or unload your logger! The COM port can be checked
in the Windows Device Manager Settings.
