10 • Next Sensor Session
Each sensor session lasts up to 10 days, plus a 12-hour grace period at the end. The
grace period gives you more time to replace your sensor so you can do it when it's
convenient for you. The time left in the grace period shows on your screen. During the
grace period, your sensor continues to work as it did during the sensor session.
You'll get alerts letting you know your sensor session or grace period will end soon.
You can choose to wear the sensor until the grace period ends or end the session
early.
To find out how much time you have left in your sensor session, go to Connections >
Sensor in the app, or in the receiver, go to Menu > Information > Sensor > Sensor
Info. When the sensor expires, the 12-hour grace period starts.
Sensor transition
You must end the sensor session or grace period before you start a new sensor. You
can end it two ways:
Automatically, when the grace period ends (you'll get an alert letting you know)
l
Manually, before the grace period ends
l
You only need to end your sensor session on one display device.
Automatically: End sensor when grace period ends
At the end of the grace period, you'll get the Start New Sensor alert:

Questions and answers
Dexcom G7 continues to show readings 50 or 60 points higher than when I stick my finger and use the supplied recorder. Why?
The Dexcom G7 may show readings 50 or 60 points higher than fingerstick measurements due to several reasons:
1. Sensor's First Day: Newly inserted sensors may show larger differences, which usually decrease over the first 24 hours.
2. Pressure on Sensor: If something is pressing on the sensor (e.g., lying on it), it can affect readings. Removing the pressure can help.
3. Rapid Glucose Changes: Blood glucose changes before interstitial fluid glucose, so fast changes can cause differences between meter and sensor readings.
4. Fingerstick Issues: Inaccurate fingerstick readings can occur if hands are not washed properly or test strips are expired or used incorrectly.
These factors can cause temporary differences between Dexcom G7 and fingerstick readings.
