InTemp® CX600 Dry Ice/CX700 Cryogenic Logger Manual 
22025-A 
InTemp CX600 Dry Ice and CX700 Cryogenic loggers are designed for cold shipment monitoring 
and have a built-in external probe that can measure temperatures as low as -95°C (-139°F) for 
the CX600 series or -200°C (-328°F) for the CX700 series. The loggers include a protective 
sheath to prevent cutting the cable during shipment and a clip for mounting the probe. 
Designed for wireless communication with a mobile device, these Bluetooth® Low Energy-
enabled loggers use the InTemp app, and InTempConnect® web-based software to form the 
InTemp temperature monitoring solution. Using the InTemp app on your phone or tablet, you 
can configure the loggers and then download them to share and view logger reports, which 
include logged data, excursions, and alarm information. When you are logged into the app as 
an InTempConnect user, downloaded logger data is also automatically uploaded to 
InTempConnect, where you can build custom reports and monitor trip information. Both the 
CX600 and CX700 series loggers are available in single-use 90-day models (CX602 and CX702) or 
multiple-use 365-day models (CX603 or CX703).

c. InTempConnect users: Log in with your InTempConnect 
user credentials. 
App only users: If you will not be using InTempConnect, 
create a local user account and log in when prompted. 
3. Configure the logger. Note that InTempConnect users 
require privileges for configuring the logger. 
Important: CX602 and CX702 loggers cannot be 
restarted once logging begins. Do not continue with 
these steps until you are ready to use these loggers. 
a. Press the button on the logger to wake it up. 
b. Tap the Devices icon in the app. Find the logger in the list and 
tap it to connect to it. If you are working with multiple 
loggers, press the button again to bring the logger to the top 
of the list. 
If you are having trouble connecting: 
• Make sure the logger is within range of your mobile 
device. The range for successful wireless communication 
is approximately 30.5 m (100 ft) with full line-of-sight. 
• If your device can connect to the logger intermittently or 
loses its connection, move closer to the logger, within 
sight if possible. 
• Change the orientation of your phone or tablet to ensure 
the antenna in your device is pointed toward the logger. 
Obstacles between the antenna in the device and the 
logger may result in intermittent connections. 
• If the logger appears in the list, but you cannot connect 
to it, close the app, power down the mobile device, and 
then turn it back on. This forces the previous Bluetooth 
connection to close. 
c. Once connected, tap Configure. Swipe left and right to 
select a logger configuration. Type a deployment name. 
Tap Start to load the selected configuration to the logger. 
InTempConnect users: If trip information fields were set 
up, you will be prompted to enter additional information. 
Tap Start in the upper right corner when done. 
4. Deploy and start the logger. 
Important: Reminder, CX601 and CX602 loggers cannot 
be restarted once logging begins. Do not continue with 
these steps until you are ready to use these loggers. 
a. Deploy the logger to the location where you will be 
monitoring the temperature. 
b. Press the button on the logger when you want logging to 
begin (or if you chose a custom configuration, logging will 
begin based on the settings in the configuration). 
If the logger was configured with alarm settings, an alarm will 
trip when the temperature reading is outside the range 
specified in the logger configuration. The logger alarm LED will 
blink every 4 seconds, an alarm icon appears in the app, and an 
Alarm Out of Range event is logged. You can review alarm 
information in the logger report (see Downloading the Logger). 
InTempConnect users can also receive notifications when an 
alarm is tripped. See www.intempconnect.com/help for more 
details on configuring the logger and monitoring alarms. 
Passkey Protection 
The logger is protected by an encrypted passkey automatically 
generated by the InTemp app for InTempConnect users and 
optionally available for local users who are using the app only. 
The passkey uses a proprietary encryption algorithm that 
changes with every connection. 
InTempConnect Users 
Only InTempConnect users belonging to the same 
InTempConnect account can connect to a logger once it is 
configured. When an InTempConnect user first configures a 
logger, it is locked with an encrypted passkey that is 
automatically generated by the InTemp app. After the logger is 
configured, only active users associated with that account will 
be able to connect to it. If a user belongs to a different account, 
that user will not be able to connect to the logger with the app, 
which will display an invalid passkey message. Administrators 
or users with the required privileges can also view the passkey 
from the device deployment page in InTempConnect and share 
them if needed. See www.intempconnect.com/help for more 
details. 
Local Users 
If you are not using InTempConnect and instead logging into 
the app as a local user, you can create an encrypted passkey for 
the logger that will be required if another phone or tablet 
attempts to connect to it. This is recommended to ensure that 
a deployed logger is not mistakenly stopped or purposely 
altered by others. 
To set a passkey: 
1. Press the button on the logger to wake it up. 
2. Tap the Devices icon and connect to the logger. 
3. Tap Set Logger Passkey. 
4. Type a passkey up to 10 characters. 
5. Tap Save. 
6. Tap Disconnect. 
Only the phone or tablet used to set the passkey can then 
connect to the logger without entering a passkey; all other 
mobile devices will be required to enter the passkey. For 
example, if you set the passkey for the logger with your tablet 
and then try to connect to the device later with your phone, 
you will be required to enter the passkey on the phone but not 
with your tablet. Similarly, if others attempt to connect to the 
logger with different devices, then they would also be required 
to enter the passkey. To reset a passkey, connect to the logger, 
tap Set Logger Passkey, and select Reset to Factory Default.

Logger Events 
The logger records the following events to track logger 
operation and status. These events are listed in reports 
downloaded from the logger. 
Event Name  Definition 
Configured  The logger was configured by a user. 
Connected  The logger was connected to the app 
during deployment. 
Started  The logger started logging. 
Stopped  The logger stopped logging. 
Event Name Definition 
Downloaded  The logger was downloaded. 
Alarm Out of 
Range/In Range 
An alarm has occurred because the reading 
was outside the alarm limits or back within 
range. Note: Although the reading may 
return to a normal range, the alarm 
indicator will not clear in the app and the 
alarm LED will continue to blink.  
Safe Shutdown  The battery level dropped below a safe 
operating voltage and performed a safe 
shutdown. 
Deploying the Logger 
Use the mounting loop on the logger to secure it to a shipment 
or other application you are monitoring. You can also remove 
the backing on the tape that is adhered to the top and bottom 
of the logger to mount it on a flat surface. 
Place the stainless steel probe in the plastic clip included with 
the logger and clip it to a box or other item. 
The external probe cable has a protective sheath. Move the 
sheath as needed to position it where the cable will be 
protected during shipments from inadvertent cuts. 
Protecting the Logger 
Note: Static electricity may cause the logger to stop logging. 
The logger has been tested to 8 KV, but avoid electrostatic 
discharge by grounding yourself to protect the logger. For more 
information, search for “static discharge” on onsetcomp.com. 
Battery Information 
The logger uses one CR2450 non-replaceable lithium battery. 
Battery life is not guaranteed past the 1-year logger shelf life. 
Battery life for the CX603 and CX703 models is 1 year, typical 
with a logging interval of 1 minute. Expected battery life for the 
CX603 and CX703 models vary based on the ambient 
temperature where the logger is deployed and the frequency of 
connections, downloads, and paging. Deployments in extremely 
cold or hot temperatures or a logging interval faster than 1 
minute can impact battery life. Estimates are not guaranteed 
due to uncertainties in initial battery conditions and operating 
environment. 
 WARNING: Do not cut open, incinerate, heat above 85°C 
(185°F), or recharge the lithium battery. The battery may 
explode if the logger is exposed to extreme heat or conditions 
that could damage or destroy the battery case. Do not dispose 
of the logger or battery in fire. Do not expose the contents of 
the battery to water. Dispose of the battery according to local 
regulations for lithium batteries.
