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.
