InTemp™ CX Temperature Logger (CX40x) Manual

InTemp CX400 series loggers measure temperature in indoor monitoring applications. Designed to
meet World Health Organization (WHO) and Centers for Disease Control and Prevention (CDC)
guidelines, this logger is ideal for clinical applications, such as vaccine storage and pharmaceutical
manufacturing. This Bluetooth® Low Energy-enabled logger is designed for wireless
communication with a mobile device. Using the InTemp app, you can easily configure the logger
with one of four preset configurations designed for ambient storage, clinical refrigerator, freezer,
or refrigerator monitoring or you can set up a custom configuration for other applications. You
can also quickly perform daily logger checks, download reports, and monitor tripped alarms. Use
the built-in LCD screen to check the current temperature, daily maximum or minimum
temperatures, logging status, battery use, and more. The CX402 model uses a 2- or 4-meter probe
and is available with a 5, 15, or 30 mL glycol bottle (bottle holder included). It also contains an
internal sensor for ambient temperature monitoring. The CX403 model is available with an
internal sensor only.

Start Button: Press this button for 1 second to start the logger
when it is configured to start “on button push” (see Configuring
the Logger).

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.

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.

remaining.

The logger is currently logging.

The logger is currently connected to a phone or
tablet via BlueTooth. The more bars there are, the
stronger the signal.

The logger is waiting to be started. Press and hold
the Start button for 3 seconds to start the logger.

This is an example of a temperature reading from
an external probe.

This is an example of a temperature reading from
the internal sensor.

This is an example of a minimum temperature,
which is the lowest probe temperature reading
from the day (CX402 models) or the lowest
ambient temperature reading (CX403 model).

This is an example of a maximum temperature,
which is the highest probe temperature reading
from the day (CX402 models) or the lowest
ambient temperature reading (CX403 model).

The external probe is not connected to the logger
(if applicable).
