Getting Started: Using HOBOware with HOBO Data Loggers 15
Testing the Logger and Sensors
To verify that your logger and sensors are working and recording data
properly, perform the following tests. When you plot the data later,
you should see the results of these tests in the graph.
Change Sensor Reading:
1. Force a change in the condition you are measuring. For example,
if you are measuring temperature, change the temperature
reading by holding the logger or sensor in your hands for a minute
or two.
2. Watch the Current Readings in the Status window change as the
conditions fluctuate.
Change Current State:
1. If you are using a U-Series logger that has a button, hold the
button down for several seconds.
2. Watch the Current State
field in the Status window change to
“Button Down.”
3. Release the button. The Current State field changes back to
“Button Up.”
Click OK to close the Status window when the tests are complete.

Reading Out the Logger
To retrieve data recorded by a logger, you must read out the logger.
Reading out the logger copies data from the logger to your computer,
allowing you to save the data in a datafile and view the plot.
During readout, the logger continues to record data unless you have
stopped the logger or the logger is full.
To read out the logger:
1. Click the Readout icon
on the toolbar.
2. A warning message appears indicating the logger is currently
logging. Click Don’t Stop to continue logging or Stop
to end
logging before reading out.
3. After reading out the logger, you are prompted to save the datafile.
Type a name and select a location for the file and click Save.
The Plot Setup window appears, which is described in the next section.
