How do I calibrate the Dexcom G6® for the first time?

The Dexcom G6® CGM System is designed to work properly without requiring calibrations:

  • Enter the unique sensor code that was printed on each sensor’s adhesive label during startup and you’re done.
  • If you don’t enter a sensor code, you’ll be prompted to manually calibrate your system using values obtained from a blood glucose meter and fingersticks.
  • Sensors require a 2-hour warmup period. (Use a blood glucose meter to make treatment decisions during that time.)
  • When you start a new sensor, you won’t get any readings or alarms/alerts until you enter your sensor code or two calibrations.
