Introduction

In this article, we will discuss the eight most common errors that users encounter when using the Freestyle Libre system, as well as provide solutions on how to fix them. The Freestyle Libre system is a popular and convenient way for individuals with diabetes to monitor their blood sugar levels. However, like any technology, there can be occasional errors and issues that arise during its usage. Understanding these errors and knowing how to troubleshoot them can help ensure a smooth and hassle-free experience with the Freestyle Libre system.

Scan Timeout

One of the common errors that users may encounter with the Freestyle Libre system is a scan timeout. This error occurs when the reading device is not held close enough to the sensor. The Freestyle Libre system uses NFC (Near Field Communication) technology to transfer data between the sensor and the reading device. It is important to hold the antenna of the reading device within four centimeters or one and a half inches of the sensor to ensure a successful scan. Different devices may have varying antenna placements, so it is crucial to be aware of the NFC antenna location on your specific device.

Check Sensor

The check sensor error is another error that users may come across while using the Freestyle Libre system. This error typically indicates that the sensor filament is not properly placed or inserted beneath the skin. The filament is responsible for gathering readings from the interstitial fluid. If you encounter the check sensor error after a few days of using the sensor, it likely means that the filament has been dislodged or ripped out. Unfortunately, this cannot be fixed, and a new sensor will need to be applied and activated. However, if you experience the check sensor error during the initial setup, you can try rescanning. If the error persists, it is likely due to an improper sensor application, and a new sensor must be used.

Scan Error

The scan error occurs when the reading device is unable to communicate with the sensor. This can be resolved by attempting to scan again after a brief pause. It is also important to note that sources of electromagnetic interference, such as televisions or radios, can disrupt communication between the reading device and the sensor. If you encounter a scan error, try moving away from these sources and attempt another scan.

Sensor Already In Use

If you encounter the sensor already in use error, it means that you are attempting to scan the sensor with a device other than the one it was initially activated with. Each sensor can only be used with one device, and that device is the one it was initially activated with. If you still have access to the device that was used for activation, use that device for scanning and obtaining readings.

Sensor Error

The sensor error, also known as "try scanning again in 10 minutes," is one of the most common and frustrating errors encountered by users. This error occurs when blood sugar levels fluctuate significantly, causing inconsistent readings. In these situations, it is recommended to wait at least 10 minutes before rescanning. This gives the system time to stabilize and provide accurate readings.

Replace Sensor

The replace sensor error indicates that the current sensor is no longer functioning and needs to be replaced. This error usually occurs before the 14-day wear time of the sensor has expired. If this happens, you are entitled to a free replacement as you were unable to use the sensor for its intended duration. To obtain a free replacement, ensure that you have the sensor's serial number on hand, which can be found on the side of each sensor or the bottom of the package. It is also helpful to gather any additional evidence, such as photos or videos, to support your claim.

New Sensor Found

The new sensor found message appears when you scan a new sensor before the expiry of your old sensor. The old sensor is still active, and by scanning a new one, you are indicating your intention to use it. It is important to note that your device can only be used with one sensor at a time. If you wish to start using the new sensor, confirm the device's prompt to switch sensors.

Sensor Ended

The sensor ended error simply informs you that the 14-day wear time of the sensor has elapsed, and it is time to replace it. To replace the sensor, peel off the old one and apply a new sensor following the activation process. For a step-by-step guide on applying and activating a new sensor, refer to the instructional video provided.

Conclusion

The Freestyle Libre system offers individuals with diabetes a convenient method of monitoring their blood sugar levels. However, errors may occur during usage, which can be frustrating. By understanding the common errors discussed in this article and following the recommended solutions, users can ensure a smooth and accurate experience with the Freestyle Libre system. Remember to consult your healthcare provider for any concerns or questions regarding the Freestyle Libre system.

Highlights

  • Understand common errors and their solutions when using the Freestyle Libre system
  • Scan Timeout: Ensure the reading device is held close enough to the sensor
  • Check Sensor: Apply and activate a new sensor if the filament is dislodged
  • Scan Error: Retry scanning in an area free from electromagnetic interference
  • Sensor Already In Use: Use the device that the sensor was activated with for scanning
  • Sensor Error: Wait for 10 minutes before rescanning in cases of erratic blood sugar levels
  • Replace Sensor: Claim a free replacement if the sensor malfunctions before the 14-day wear time
  • New Sensor Found: Confirm the device prompt if intending to use a new sensor
  • Sensor Ended: Replace the sensor after the 14-day wear time

FAQ

Q: Can I fix a check sensor error? A: Unfortunately, a check sensor error usually indicates that the filament has been dislodged, and a new sensor needs to be applied and activated.

Q: How can I troubleshoot a scan error? A: To troubleshoot a scan error, attempt to scan again after a short pause. Ensure that there are no sources of electromagnetic interference nearby, such as televisions or radios.

Q: Will I need evidence to claim a free replacement for a malfunctioning sensor? A: Yes, it is recommended to keep evidence, such as photos or videos, to support your claim for a free replacement when a sensor malfunctions before the 14-day wear time.

Q: Can I use multiple sensors simultaneously? A: No, each sensor can only be used with one device at a time. If you start using a new sensor, the old sensor will no longer be active.

Q: What should I do when encountering a sensor error? A: When encountering a sensor error, it is best to wait for at least 10 minutes before rescanning to allow the system to stabilize and provide accurate readings.

Q: Where can I find the sensor's serial number? A: The sensor's serial number can be found on the side of each sensor or at the bottom of the package.
