Mounting the Logger
There are several ways to mount the logger using the materials
included:
•
Use the four built-in magnets on the back of the logger to
mount it to a magnetic surface.
•
Attach the Command strip to the back of the logger to
mount it a wall or other flat surface.
•
Use the double-sided tape to affix the logger to a surface.
•
Insert the hook-and-loop strap through the mounting
loops on both sides of the logger to mount it to a curved
surface, such as a pipe or tubing.
Protecting the Logger
The logger is designed for indoor use and can be permanently
damaged by corrosion if it gets wet. Protect it from
condensation. If the message FAIL CLK appears on the LCD
screen, there was a failure with the internal logger clock
possibly due to condensation. Remove the battery immediately
and dry the circuit board.
Note: Static electricity may cause the logger to stop logging.
The logger has been tested to 8 KV, but avoid electrostatic
discharge by grounding yourself to protect the logger. For more
information, search for “static discharge” on
www.onsetcomp.com.
Battery Information
The logger contains a 3V CR2032 battery (HRB-TEMP). Expected
battery life varies based on the ambient temperature where
the logger is deployed, the logging or sampling interval,
frequency of offloading to the computer, number of channels
that are active, if burst or statistics logging modes are active,
and battery performance. A new battery typically lasts 1 year
with logging intervals greater than 1 minute. Deployments in
extremely cold or hot temperatures, a logging interval faster
than 1 minute, or a sampling interval faster than 15 seconds
can impact battery life. Estimates are not guaranteed due to
uncertainties in initial battery conditions and operating
environment.
The logger can also be powered by the USB cable when the
remaining battery voltage is too low for it to continue logging.
Connect the logger to the computer, click the Readout button
on the toolbar, and save the data as prompted. Replace the
battery before launching the logger again.
To replace the battery:
1. Holding the logger with the LCD screen facing up, pull the
battery tray out of the logger housing.
2. Remove the old battery from the tray.
3. Place the new battery in the tray with the positive side
facing down.
4. With the LCD screen still facing up, slide the tray back into
the logger. The LCD should display “HOBO” briefly after
correctly installing the battery.
WARNING: Do not cut open, incinerate, heat above 85°C
(185°F), or recharge the lithium battery. The battery may
explode if the logger is exposed to extreme heat or conditions
that could damage or destroy the battery case. Do not dispose
of the logger or battery in fire. Do not expose the contents of
the battery to water. Dispose of the battery according to local
regulations for lithium batteries.
HOBOware provides the option of recording the current battery
voltage at each logging interval, which is disabled by default.
Recording battery life at each logging interval takes up memory
and therefore reduces logging duration. It is recommended you
only record battery voltage for diagnostic purposes.
