Logger Components and Operation
Start Button:
Press this button for 1 second to start the logger
when it is configured to start “on button push.”
Mute or Next Button:
Press this button for 1 second to mute a
beeping alarm (see
Logger Alarms
). For CX402 loggers, press
this button for 1 second to switch between the external probe
and ambient internal sensor temperature readings.
Magnets:
There are four magnets on the back of the logger (not
shown in diagram) for mounting.
Temperature Sensor:
This internal sensor measures ambient
temperature.
External Temperature Probe:
This is the probe that is plugged
into the logger for measuring temperature (CX402 models
only).
Audible Alarm Speaker:
This is the speaker for the audible
alarm that beeps when an alarm is tripped or the external
probe is removed (if applicable).
Alarm LED:
This LED blinks every 5 seconds when an alarm is
tripped or the external probe is removed (if applicable). See
Logger Alarms
.
LCD
: This screen shows the latest temperature reading and
other status information. The LCD screen refreshes at the same
rate as the logging interval. The example shows all symbols
illuminated on the LCD screen followed by a table with
descriptions of each symbol.
LCD Symbol
Description
An alarm has tripped because the temperature
reading is outside the specified range
The logger has been configured to perform daily or
twice daily checks (twice daily is shown in this
example), but no checks have been performed yet.
The once daily or twice daily logger check (twice in
this example) has been performed.
This indicates how much memory has been used
for the current deployment. In this example,
approximately 40 percent of the memory has been
used.
This shows the approximate battery power
remaining.
