InTemp® CX400 Series Temperature Logger 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. Or, you can use InTempConnect® to configure and download CX series
loggers via the CX5000 Gateway. Use the built-in LCD screen on the logger to check the current
temperature, daily maximum or minimum temperatures, logging status, battery use, and more.
Once data is uploaded to InTempConnect, you can track logger deployments and automatically
upload logger data to build custom reports for further analysis. The CX402 model uses a 2- or 4­meter 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.”

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

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.

LCD Symbol Description

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)
within the current 24-hour period (midnight from
one day to midnight the next day) if the logger
was set to record logger checks (see Performing
Logger Checks). Otherwise the minimum and
maximum readings represent the entire logging
period and only reset when the logger is
downloaded and restarted or stopped and
reconfigured.

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)
within the current 24-hour period (midnight from
one day to midnight the next day) if the logger
was set to record logger checks (see Performing
Logger Checks). Otherwise the minimum and
maximum readings represent the entire logging
period and only reset when the logger is
downloaded and restarted or stopped and
reconfigured.

The external probe is not connected to the logger

and

(if applicable).

MUTE indicates an alarm is beeping. Turn off the

or

beeping alarm by pressing the Mute button. The
LCD then changes to MUTED.

The audible alarm has been muted.

The logger has been configured to start logging on
a delay. The display will count down in days,
hours, minutes, and seconds until logging begins.
In this example, 5 minutes and 38 seconds remain
until logging will begin.

The configuration settings are being loaded onto
the logger from the app.

An error occurred while loading the configuration
settings onto the logger from the app. Try
reconfiguring the logger.

The logger was paged from the app.

The logger has been downloaded and stopped
with the app or because the memory is full.

The logger is being updated with new firmware.

Note: If the logger has stopped logging because the memory is
full, the LCD screen will remain on with “STOP” displayed until
the logger is downloaded to your mobile device. Once the
logger has been downloaded, the LCD will turn off
automatically after 2 hours. The LCD will turn back on the next
time the logger connects with your device.

Getting Started

InTempConnect is web-based software where you can monitor
CX400 series logger deployments and view downloaded data
online. Using the InTemp app, you can configure the logger
with your phone or tablet and then download reports, which
are saved in the app and automatically uploaded to
InTempConnect. The CX5000 Gateway is also available to
automatically configure and download loggers and upload data
to InTempConnect (see www.intempconnect.com/help for
details). You also have the option to use the logger with the
InTemp app only.

Follow these steps to begin using the loggers with
InTempConnect and the InTemp app.

1. Administrators: Set up an InTempConnect account. Follow
all steps if you are a new administrator. If you already have
an account and roles assigned, follow steps c and d.

If you are using the logger with the InTemp app only, skip
to step 2.

a. Go to www.intempconnect.com and follow the prompts

to set up an administrator account. You’ll receive an
email to activate the account.

b. Log into www.intempconnect.com and add roles for the

users you will be adding to the account. Click Settings
and then Roles. Click Add Role, enter a description,
select the privileges for the role and click Save.

c. Click Settings and then Users to add users to your

account. Click Add User and enter the email address and
first and last name of the user. Select the roles for the
user and click Save.

d. New users will receive an email to activate their user

accounts.

2. Set up the logger. Insert two AAA batteries in the logger,

observing polarity. Insert the battery door in the back of the
logger making sure it is flush with the rest of the logger
case. Use the included screw and a Phillips-head
screwdriver to screw the battery door into place.

Insert the external temperature probe (if applicable).

3. Download the InTemp app and log in.

a. Download InTemp to a phone or tablet from the App

Store® or Google Play™.

b. Open the app and enable Bluetooth in the device settings

if prompted.

c. InTempConnect users: Log in with your InTempConnect

user credentials. (Your device must be able to connect to
the internet.)

App only users: If you will not be using InTempConnect,
create a local user account and log in when prompted.

4. Configure the logger.

InTempConnect users: Configuring the logger requires

privileges. The logger includes preset configurations.
Administrators or those with the required privileges can
also set up custom configurations (including setting up daily
logger checks) and trip information fields. This should be
done before configuring the logger.
