Download & Continue. The logger will continue logging 
once the download is complete. 

 

Download & Restart. The logger will start a new data set 
using the same profile once the download is complete. 

 

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 into the InTemp app with 
your InTempConnect user credentials. 

In the app, tap Settings to change the default report type and 
report sharing options. The report is also available in Secure 
PDF, XLSX, and VFC CSV (if enabled) 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. 

Performing Logger Checks 

If your monitoring application requires that you perform daily 
or twice daily checks of the logger, you can use the InTemp app 
to connect to the logger and perform a check. 

To enable the perform check feature in the InTemp app (if you 
are not using InTempConnect): 

1.

 

Tap the Settings icon. 

2.

 

Under Record CX400 Logger Checks, select either Once 
Daily or Twice Daily. If you choose Twice Daily, a Perform 
Morning Check action will be listed in the Connected screen 
from 12:01 AM until 12:00 PM and then a Perform 
Afternoon Check action will be listed from 12:01 PM to 
12:00 AM. If you choose Once Daily, an action will be listed 
in the Connected screen to Perform Daily Check. 

To enable the perform check feature if you are using 
InTempConnect, an administrator or user with the required 
privileges must create a new profile for a CX400 logger and set 
the Daily Checks to Once Daily or Twice Daily. For details on 
managing profiles, see www.intempconnect.com/help. 

Note: 

Changes to the Record CX400 Logger Checks setting will 

take effect the next time the logger is configured. Also, when 
this setting is enabled, the minimum and maximum values 
displayed on the logger LCD represent the minimum and 
maximum readings within the current 24-hour periods and will 
reset every 24 hours. Otherwise, if this setting is not enabled, 
the minimum and maximum values represent the entire logging 
period and only reset when the logger is downloaded and 
restarted or stopped and reconfigured (they will not reset if you 
download the logger and continue logging). 

To perform a check: 

1.

 

Tap the Devices icon and connect to the logger. 

2.

 

Tap Perform (Morning, Afternoon, or Daily) Check. 

Once a check is completed, it is recorded as a logged user 
action along with the user email and the location, and is 
available for view in reports. The action is also listed as 
performed in the Connected screen and a checkmark will 
illuminate on the logger LCD. 

You can also set up a notification to display on your phone or 
tablet to remind you to perform a check. Use the Reminders 
option under Settings in the InTemp app. 

Minimum and Maximum Values 

The logger LCD displays the minimum and maximum 
temperature readings. If the setting to perform logger checks is 
enabled (see 

Performing Logger Checks

), then these values 

represent the minimum and maximum readings within the 
current 24-hour period and will reset every 24 hours for the 
entire logging period. If the logger check setting has not been 
enabled, then these values represent the entire logging period 
and will automatically reset when the logger is downloaded and 
restarted or stopped and reconfigured. 

You can also clear these values as needed while the logger is 
logging by pressing the Mute/Next button for 3 seconds until 
HOLD disappears on the LCD. Dashes (--) will then appear on the 
LCD for the minimum and maximum values until the next logging 
interval. The values will then continue to be updated for the 
remaining logging period or until they are cleared again. 

Note:

 

This clears the data on the screen only. Actual logger and 
reporting data will not be cleared with this reset. 

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 

Started 

The logger started logging. 

Stopped 

The logger stopped logging. 

Downloaded 

The logger was downloaded. 

Probe Alarm 
Tripped/Cleared 

A probe temperature alarm has tripped or 
cleared because the reading was outside the 
alarm limits or back within range. 

Performed/Missed 
Check 

The user performed or missed the daily, 
morning, or afternoon logger check. 

Safe Shutdown 

The battery level dropped below 1.85 V; the 
logger performs a safe shutdown. 

Deploying the Logger 

Use the four magnets on the back of the logger case to mount it 
to a magnetic surface. 

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 

The logger is designed for indoor use and can be permanently 
damaged by corrosion if it gets wet. Protect it from 
condensation. If the logger gets wet, remove the battery 
immediately and dry the circuit board. 

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.
