Internal Event Name
Definition
Chan <#> Alarm
Cleared
A sensor alarm has cleared; # is the channel
or sensor number as shown in the Launch
Logger window in HOBOware. This event also
contains the value that was furthest out of
range for the sensor before the alarm
cleared.
New Interval
The logger has entered or exited burst
logging mode.
Safe Shutdown
The battery level dropped below 2.5 V; the
logger performs a safe shutdown.
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.
Replacing the RH Sensor
The internal RH sensor may require replacement if it is
damaged mechanically or by exposure to condensation or
chemicals. The replacement sensor is available from Onset
(HUM-UPS-500). To replace the sensor:
1.
Use a screwdriver to pop out the louvered door in the
logger case.
2.
Use needle-nose pliers to remove the RH sensor from the
board inside the logger case and discard it.
3.
Insert the new sensor so that the pins are in the two holes
on the board (shown here enlarged and without the logger
case for illustrative purposes).
4.
Snap the louvered door back into place in the logger.
5.
Check logger status in HOBOware to verify the RH reading.
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.
