logger will take a temperature sample every 30 seconds and
temporarily store it in memory. The logger will then calculate
the maximum, minimum, average, and standard deviation using
the samples gathered over the previous 5-minute period and
log the resulting value(s). When reading out the logger, this
would result in 5 data series: one temperature series (with data
logged every 5 minutes) plus four maximum, minimum,
average, and standard deviation series (with values calculated
and logged every 5 minutes based on the 30-second sampling).
Note: Statistics are available on the thermocouple channel
only; they are not available on the internal 10K thermistor
(temperature) channel.
To set up statistics:
1. Select Statistics for Logging Mode in the Launch Logger
window. If Statistics has already been configured for this
logger, click the Edit button in the Launch Logger window.
2. Click the Maximum, Minimum, Average, and Standard
Deviation checkboxes for each of the statistics you want to
calculate during logging. Note that Average is automatically
enabled when selecting Standard Deviation. In addition, the
more statistics you record, the shorter the logger duration
and the more memory is required.
3. Set the sampling interval, which must be less than and a
factor of the logging interval. Choose either a preset
sampling interval or select Custom and enter your own
sampling interval. Keep in mind that the more frequent the
sampling rate, the greater the impact on battery life.
4. Click OK when done. This will return you to the Launch
Logger window. Click the Edit button next to Logging Mode
in the Launch Logger window to make additional changes.
Once logging begins, click the Alarm button on the logger to
cycle through the current maximum, minimum, average, and
standard deviation data on the LCD screen. You can plot the
statistics series once you read out the logger.
Reading Out the Logger
There are two options for reading out the logger: connect it to
the computer with a USB cable and read out it with HOBOware,
or connect it to a HOBO U-Shuttle (U-DT-1, firmware version
1.18m030 or higher) and then offload the data files from the
U-Shuttle to HOBOware. Refer to the HOBOware Help for details.

Recording Internal Logger Events
The logger records the following internal events to track logger
operation and status. You can plot these events in HOBOware
after reading out the logger and opening the data file.
Internal Event Name
Definition
Host Connected
The logger was connected to the computer.
Started
The Start/Stop button was pressed to begin
logging.
Stopped
The logger received a command to stop
recording data (from HOBOware or by
pushing the Start/Stop button).
Button Up/Button
The Start/Stop button was pressed for
Down
1 second.
Chan 1 Alarm
A temperature alarm has tripped.
Tripped
Chan 1 Alarm
A temperature alarm has cleared. This event
Cleared
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" in the FAQ section on
onsetcomp.com.
