Connecting the Logger
The HOBO Pendant logger requires either of the following to
connect to the computer:
•
Pendant Optic USB Base Station & Coupler (BASE-U-1);
HOBOware 2.1 or later
OR
•
Optic USB Base Station (BASE-U-4) or HOBO Waterproof
Shuttle (U-DTW-1); coupler (COUPLER2-A); HOBOware 2.2
or later
If possible, avoid connecting at temperatures below 0°C (32°F)
or above 50°C (122°F).
1. Plug the USB connector on the base station into an available
USB port on your computer.
2. Insert the logger and the base station into the coupler, as
shown in the following diagrams.
For BASE-U-1, make sure that the logger is inserted in the
end of the coupler that has the magnet, and that the ridges
on the base station and logger are aligned with the grooves
in the coupler.
For BASE-U-4 or the HOBO Waterproof Shuttle, firmly insert
the optical end of the base station into the D-shaped end of
the coupler, and make sure that the ridge on the logger is
aligned with the groove in the coupler.
3. If you are using the HOBO Waterproof Shuttle, briefly press
the coupler lever to put the shuttle into base station mode.
4. If the logger has never been connected to the computer
before, it may take a few seconds for the new hardware to
be detected.
5. Use the logger software to set up the alarms, launch, and
read out the logger.
You can read out the logger or check its status while it
continues to log, stop it manually with the software, or let it
record data until the memory is full. Refer to the software
user’s guide for complete details on launching, reading out, and
viewing data from the logger.
Important:
Do not cover the optical communication window in
the logger (shown in diagram above) with a label or sticker as
that may interfere with the communications with the base
station or shuttle.
Triggered Start
This logger can be configured to start at your command, using
the magnet in the coupler to trigger a start.
1. Use HOBOware to launch the logger with Using Coupler
selected. Remove the logger from the coupler.
2. Bring the logger and an empty coupler or strong magnet to
the deployment location.
Important:
Any magnet can trigger a start. This can be helpful,
but it can also cause a premature start. Keep the logger away
from strong magnetic fields until you are ready to begin
logging.
3. When you are ready for the logger to start logging, insert
the logger into the empty coupler (or place it next to a
strong magnet) and remove it after three seconds.
Important:
The logger will not launch if the base station is in
the coupler.
4. Verify that the logger’s light is blinking at least every four
seconds.
Sample and Event Logging
The logger can record two types of data: samples and internal
logger events. Samples are the measurements recorded at each
logging interval (for example, temperature every minute). Events
are independent occurrences triggered by a logger activity, such
as Bad Battery or Host Connected. Events help you determine
what was happening while the logger was logging.
Operation
Lights (LEDs) on the front of the logger confirm logger
operation. The following table explains when the lights blink
during logger operation.
When: The
Lights:
The logger is logging
faster than four
seconds
Blink at the logging interval:
• Green LED if temperature is OK
• Red LED if high alarm has been triggered
• Blue LED if low alarm has been triggered
The logger is logging at
four seconds or slower
Blink every four seconds:
• Green LED if temperature is OK
• Red LED if high alarm has been triggered
• Blue LED if low alarm has been triggered
The logger is awaiting
a start because it was
configured to start
logging At Interval, On
Date/Time, or Using
Coupler
Green light blinks once every eight seconds
until launch begins
