6 OWL Data Loggers
How long do I need to record data?
How much time will elapse between when I retrieve the logger(s) and download the data to my
computer (i.e. the trip back to the office)?
How often do readings need to be taken?
Making External Connections
If you are using your OWL Data Logger to monitor external modules, sensors, or circuitry, make sure
the connections are secure.
Clear Memory
Before sending your logger out into the field to collect data, empty the logger memory. This will help to
keep the collected files smaller as well as decrease the time needed to backup the logger later. Note
that clearing your OWL's memory is automatic if you make setup changes (i.e. assign different
equations, change filename, etc.)
Test
You can directly read the values that your OWL Data Logger is sensing by Examining the logger. To do
this, double click on the com port icon, and point the LIC-101 wand at the logger's optical port. The
current reading will be displayed. To retrieve updated readings, choose Close, then repeat the previous
steps. You must examine the logger at intervals longer than the sample rate to retrieve a valid reading.
(See Fig. 2.)
Label
OWLs can be setup with a description that can be put into the logger's memory. It is recommended
that you use this feature in order to know what each graph refers to.
