Logger Components and Operation
Start/Stop Button: Press this button for 3 seconds to start or
stop logging data, or to resume logging on the next even
logging interval. This requires configuring the logger in
HOBOmobile with a push button start or stop, and with Allow
Button Restart selected (see Setting up the Logger). You can
also press this button for 1 second to record an internal event
(see Recording Internal Logger Events), to silence a beeping
alarm (see Setting up Alarms), or to turn the LCD screen on if
the option to turn off the LCD has been enabled (see Setting up
the Logger).
Press both the Start/Stop button and the Alarm/Stats button
simultaneously for 3 seconds to reset a logger password.
Alarm/Stats Button: Press this button for 1 second to switch
between statistics, alarm readings, and the current sensor
readings as applicable or to silence a beeping alarm. Press this
button for 3 seconds to clear a visual alarm if the logger was
configured in HOBOmobile to maintain the visual alarm until
the alarm button was pressed (see Setting up Alarms).
