- Important: Reminder, CX502 loggers cannot be restarted once logging begins. Do not continue with these steps until you are ready to use these loggers.
- Deploy the logger to the location where you will be monitoring the temperature.
- Press the button on the logger when you want logging to begin (or if you chose a custom profile, logging will begin based on the settings in the profile).
If the logger was configured with alarm settings, an alarm will trip when the temperature reading is outside the range specified in the logger profile. 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 if you are using
the InTemp 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 InTemp app, which will display an invalid
passkey message. Administrators or users with the required privileges can also
view the passkey from the device configuration page in InTempConnect and share
them if needed. See
www.intempconnect.com/help for more
details. Note: This does not apply to InTempVerify. if the logger was
configured with a logger profile in which InTempVerify was enabled, then
anyone can download the logger with the InTempVerify app.
InTemp App Only Users
If you are using the InTemp app only (not logging in as an InTempConnect
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:
- Tap the Devices icon and connect to the logger.
- Tap Set Logger Passkey.
- Type a passkey up to 10 characters.
- Tap Save.
- 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.
Downloading the Logger
You can download the logger to a phone or tablet and generate reports that include logged data and alarm information. Reports can be shared immediately upon download or accessed later in the InTemp app. InTempConnect users: Privileges are required to download, preview, and share reports in the InTemp app. Report data is automatically uploaded to InTempConnect when you download the logger. Log in to InTempConnect to build custom reports (requires privileges). In addition, InTempConnect users can also download CX loggers automatically on a regular basis using the CX5000 Gateway. Or, if the logger was configured with a logger profile in which InTempVerify was enabled, then anyone can download the logger with the InTempVerify app. For details on the gateway and InTempVerify, see www.intempconnect.com/help. To download the logger with the InTemp app:
- Tap the Devices icon and connect to the logger.
- Tap Download.
- Choose a download option:
Important: CX502 loggers cannot be restarted. If you want a CX502 logger to continue logging after the download is complete, select Download & Continue.
- Download & Continue. The logger will continue logging once the download is complete.
- Download & Restart (CX503 models only). The logger will start a new data set using the same profile once the download is complete. Note that if the logger was originally configured with a push-button start, you must push the start button for logging to restart.
- Download & Stop. The logger will stop logging once the download is complete.
A report of the download is generated and is also uploaded to InTempConnect if you are logged in to the InTemp app with your InTempConnect user credentials. In the app, tap Settings to change the default report type (Secure PDF or XLSX) and report sharing options. The report is also available in both formats for sharing at a later time. Tap the Reports icon to access previously downloaded reports. See www.intempconnect.com/help for details on working with reports in both the InTemp app and InTempConnect.
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 InTemp app.
- Started: The logger started logging.
- Stopped: The logger stopped logging.
- 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 InTemp 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.
Protecting the Logger
Note: Static electricity may cause the logger to stop logging. The logger has
been tested to 8 VK, 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 for
the CX502 is not guaranteed past the 1-year logger shelf life. Battery life
for the CX503 model is 1 year, typical with a logging interval of 1 minute.
Expected battery life for the CX503 varies 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 the
operating environment.
