Let’s G5x! The Basics:
Starting a Sensor Session: Inserting Sensor, Attaching
Transmitter, and Starting Your Session
6.1 Introduction
Now that your display devices are set up, you’re ready to begin a sensor
session. If this is your first time inserting a sensor, you may want to watch the
G5x sensor insertion video to get a better understanding of the process.
There are three ways to get the sensor insertion video:
1. Through the app
2. On the USB card in your receiver package
3. Online at dexcom.com:
a. Top of page, click Support
After inserting the sensor, start the sensor warmup on your smart device and
receiver. The sensor warmup takes approximately two hours; during this time
your body is getting used to the new sensor, allowing for more accurate
sensor glucose readings. Once the two-hour sensor warmup has passed, you
enter two back-to-back fingerstick measurements to calibrate the sensor’s
glucose readings with your fingerstick measurements (Calibration is covered
in the next chapter).
Make sure you give yourself enough time to finish the startup session.
Remember your smart device’s Bluetooth needs to pair with the transmitter,
adding up to 30 minutes to your wait time. Good news is you don’t need to sit
around waiting: as long as you have your display device near, you can go
about your day running errands, gardening, personalizing the G5x settings,
whatever you choose during that time frame.
Keep your display device(s) handy during the warmup period—it shows how
much time has passed, notifying you with beeps and an icon when your
sensor session is ready for its startup calibrations.
