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 
HOBOware with a push button start or stop, and with “Resume 
logging on next button push” 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

) or to 

turn the LCD screen on if the option to turn off the LCD has 
been enabled (see 

Setting up the Logger

). 

Battery Tray:

 Remove the battery tray on the top of the logger 

to access the logger battery (see 

Battery Information

). 

Alarm/Stats Button

: Use this button to clear a tripped alarm 

(see 

Setting up Alarms

) or to switch between statistics, alarm 

readings, and the current sensor readings. 

Mounting Loops:

 Use the two mounting loops to mount the 

logger with the hook-and-loop strap (see 

Mounting the Logger

). 

External Temp/RH Sensor:

 The external temperature and RH 

sensors are at the end of the sensor cable, which is attached to 
logger. 

USB Port:

 Use this port to connect the logger to the computer 

or the HOBO U-Shuttle via USB cable (see 

Setting up the Logger 

and 

Reading Out the Logger

). 

LCD Screen:

 This logger is equipped with an LCD screen that 

displays details about the current status. This example shows all 

symbols illuminated on the LCD screen followed by definitions 
of each symbol in the table below. 

 

LCD Symbol 

Description 

 

The logger is waiting to be launched. Press and 
hold the Start/Stop button for 3 seconds to launch 
the logger. 

 

The logger has been launched with a push button 
stop enabled; press and hold the Start/Stop 
button for 3 seconds to stop the logger. 

Note

: If 

you also launched the logger with a push button 
start, this symbol will not appear on the display for 
30 seconds. 

 

The battery indicator shows the approximate 
battery power remaining. 

 

The logger has been configured to stop logging 
when memory fills. The memory bar indicates the 
approximate space remaining in the logger to 
record data. When first launched, all five segments 
in the bar will be empty. In this example, the 
logger memory is almost full (only one segment in 
the memory bar is empty). 

 

The logger has been configured to never stop 
logging (wrapping). The logger will continue 
recording data indefinitely, with newest data 
overwriting the oldest data. When first launched, 
all five segments in the memory bar will be empty. 
In this example, the memory is full (all five 
segments are filled in) and new data is now 
overwriting the oldest data. This will continue until 
the logger is stopped or the battery runs out. 

The logger is currently logging. 

 

A sensor reading is above or below the high or low 
alarm that you configured. Press and release the 
Alarm/Stats button until the “alm” symbol 
(described below) is displayed on the screen. This
