Error Message: Sensor Error

This message means the app is not yet ready to scan your sensor. This may be because your device needs additional time for the warm-up.

Tap on the sensor error message. If it says "Scan again in -- Hours", please wait until the amount of time displayed and then check for a reading. If "Check again in 10 Minutes" has been showing for less than 2 hours, please wait until 2 hours have elapsed, then check for a reading.

If you are still seeing the error after following these steps, the sensor will need to be replaced.
