This guide explains how to set up xDrip to use G7 or One+.

A G7 device operates for 10.5 days. Dexcom refers to the additional 12 hours beyond the standard 10-day period as the grace period. You have several options for utilizing this grace period, and you can also combine these methods.

1- Flexibility
Using each sensor for the full 10 days allows the extra 12-hour grace period to provide flexibility. For instance, if an unexpected errand arises exactly on the 10th day and you cannot start a new sensor as planned, you will have an additional 12 hours to complete your errand and start the new sensor while the old one remains functional.

2- Extended run time
You can choose to use each sensor for the full 10.5 days instead of 10. To do this, if you start a sensor at 7:00 AM, you must start the next one at 7:00 PM. This means you’ll alternate between starting sensors in the morning and evening. By using each sensor for 10.5 days, 9 sensors will last a total of 94.5 days.

3- Presoak
You can insert your new sensor while the old one is still active. For example, you might insert your new sensor at 7:00 AM but keep the old sensor running until 7:00 PM. This way, when the old sensor stops working, the new sensor will have already been active for several hours. Since readings from a new sensor can be unstable initially, this method helps ensure more reliable data by allowing the old sensor to remain functional while the new one stabilizes.


xDrip sensor expiry

xDrip considers a G7 sensor to last 10.5 days before expiring. Therefore, when you start a sensor, xDrip will display an expiration time of 10.5 days.
