Logger Components and Operation
Mounting Holes:
Use the holes at the top and bottom of the
logger to mount it (see
Deploying and Mounting the Logger
).
Alarm LED:
This LED blinks red every 4 seconds when an alarm
is tripped (unless Show LED is disabled as described in
Configuring the Logger
). Both this LED and the status LED will
blink once when you press the start button to wake up the
logger before configuring it. If you select Page Logger LED in the
HOBOmobile app, both LEDs will be illuminated for 4 seconds.
Status LED:
This LED blinks blue every 4 seconds when the
logger is logging (unless Show LED is disabled as described in
Configuring the Logger
). If the logger is waiting to start logging
because it was configured to start “On Button Push” or with a
delayed start, it will blink green every 8 seconds.
Start Button:
Press this button for 1 second to wake up the
logger; both the alarm and status LEDs will blink. Once the
logger is awake, press this button for 1 second to move it to the
top of the loggers list in HOBOmobile. Press this button for 4
seconds to start or stop the logger when it is configured to start
or stop “On button push” (see
Configuring the Logger
). Both
LEDs will blink four times when you press the button to start or
stop logging. Press this button for 10 seconds to reset a
password (see
Setting a Password
).
External Sensor:
This is the external probe attached to the
bottom of the logger that measures temperature or
temperature/RH. The MX2302 logger has one external sensor
that measures both temperature and RH. The MX2303 logger
(shown at left) has two external temperature sensors while the
MX2304 logger has one external temperature sensor.
Vent:
This vent is on the front of the models with internal
sensors (MX2301 and MX2305). In the MX2301 model, the RH
sensor is located behind the vent.
