What Is Freestyle Libre 2 CGM System?

The Freestyle Libre 2 Continuous Glucose Monitoring (CGM) System is a medical device designed for individuals with diabetes to monitor their blood glucose levels continuously. 

It consists of a small sensor that is placed on the back of the upper arm, which measures glucose levels in the interstitial fluid. 

Users can scan the sensor with a handheld reader or a compatible smartphone to obtain real-time glucose readings, trend information, and historical data.

One of the key features of the Freestyle Libre 2 system is its ability to alert users when their glucose levels go too high or too low, providing added convenience and safety. 

This CGM system eliminates the need for routine fingerstick blood glucose testing, offering greater convenience and insights into glucose control. 

It empowers individuals with diabetes to make informed decisions about their diet, medication, and lifestyle adjustments to better manage their condition and improve their quality of life.

Error Codes in CGM Devices

Continuous Glucose Monitoring (CGM) devices may display error codes or messages to indicate various issues or problems with the device or sensor. 

These error codes are designed to help users troubleshoot and address problems. 

While specific error codes can vary depending on the manufacturer and model of the CGM device, here are some common types of error codes you may encounter:

Sensor Errors

• Sensor Error: This indicates an issue with the CGM sensor, such as improper insertion, sensor malfunction, or sensor dislodgment.
• Sensor Warm-up: This message may appear when you first start a new sensor, indicating that the sensor needs time to stabilize and provide accurate readings.

Receiver/Transmitter Error

This suggests a communication problem between the CGM sensor and the receiver or transmitter. It may require reconnection or troubleshooting.

Calibration Error

This error message appears when calibration is unsuccessful, often due to inaccurate or inconsistent blood glucose readings used for calibration.

Low Transmitter Battery

This indicates that the battery of the CGM transmitter is running low and needs to be replaced.

Insertion Site Problem

This may appear if there are issues with the location of the sensor on the body, such as bleeding, swelling, or irritation at the insertion site.

Data Error

Indicates that there may be an issue with the data transmission or recording process, potentially leading to gaps in glucose data.

High and Low Glucose Alerts

These are not errors but rather notifications of high or low glucose levels based on user-set thresholds.

It’s essential to consult the user manual provided by the manufacturer of your specific CGM device to understand the meaning of any error codes and how to address them.

What Is Freestyle Libre 2 Error Code ER3 373 P?

the specific error code “ER3 373 P” for the Freestyle Libre 2 Continuous Glucose Monitoring (CGM) System was not a documented or widely recognized error code. 

CGM device error codes can vary between manufacturers, and they may also have specific codes that are not publicly disclosed or widely documented.

If you are encountering this error code on your Freestyle Libre 2 CGM device, I recommend the following steps:

Consult the User Manual

Check the user manual or product documentation that came with your Freestyle Libre 2 device. The manual should contain a list of error codes and their explanations.

Contact Customer Support

If you cannot find information about the specific error code in the manual, the next step is to contact customer support or technical support provided by Abbott, the manufacturer of the Freestyle Libre system. 

They can provide guidance on how to resolve the issue or may request additional information to assist you further.

Replace the Sensor or Components

If the error persists and you are unable to resolve it with the help of customer support, you may need to consider replacing the sensor or other components of the CGM system that could be causing the error.

Troubleshooting Error Code ER3 373 P

The specific error code “ER3 373 P” for the Freestyle Libre 2 Continuous Glucose Monitoring (CGM) System was not a documented or widely recognized error code. 

However, if you encounter this error, you can try some general troubleshooting steps that can help resolve common issues with CGM systems:

Check Sensor Placement

Ensure that the sensor is correctly and securely attached to the back of your upper arm. If it’s loose or not properly adhered to, it can lead to errors. You may need to reattach the sensor.

Restart the Sensor

Some errors can be resolved by stopping and restarting the sensor. To do this, follow the instructions provided in your Freestyle Libre 2 user manual. 

This typically involves removing and reinserting the sensor or using the sensor insertion device.

Calibrate the Sensor

If your Freestyle Libre 2 system allows for calibration (not all CGM systems do), make sure you follow the calibration process accurately. Use a fingerstick glucose reading to calibrate if required.

Replace the Sensor

If the error persists and you’ve tried the above steps without success, it may be necessary to replace the sensor. 

Sensors have a limited lifespan, and if they become damaged or reach the end of their lifespan, they may not function properly.

Contact Customer Support

If the issue remains unresolved, it’s advisable to contact Abbott’s customer support or technical support for the Freestyle Libre 2 system. 

They can provide guidance on troubleshooting specific issues and may have information on any recent updates or known issues related to error codes.

Consult Your Healthcare Provider

If you continue to experience problems with your CGM system, it’s a good idea to consult your healthcare provider. 

They can offer guidance on managing your diabetes and CGM system effectively and may be able to provide further troubleshooting assistance.
