Receiver Calibration - Dexcom ONE+ User Manual

8 • Receiver calibration
You may want to calibrate your Dexcom ONE+ using a BG meter value.
If you calibrate, enter your BG meter value into the receiver only or the app only, not both. The other device will update after
about 5 minutes.
To get an accurate BG meter value, follow these steps:
1. Wash your hands with soap and water.
2. Dry your hands.
3. Take a fingerstick.
To calibrate your Dexcom ONE+ in your receiver, go to Menu > Calibrate sensor.

BG meter values and sensor readings
Your sensor readings come from different fluids than your BG meter values, so they won't usually match. Neither number is as
accurate as the lab test your healthcare provider does.
For information on accuracy and calibrating your Dexcom ONE+, go to the Accuracy and calibration section of the
Troubleshooting chapter.
