How do I start a new sensor?

You must end the Dexcom G7 sensor session or grace period before you start a new sensor. You can end it in one of two ways:

• Automatically, when the grace period ends (you’ll get an alert letting you know)
• Manually, before the grace period ends

Automatically: End sensor when grace period ends

At the end of the grace period, you’ll get the Start New Sensor alert:

Manually: End sensor before grace period ends

This applies to both Dexcom G7 and Dexcom G7 15 Day CGM Systems.
