Preparing For Calibration; Ready? Set? Calibrate - Dexcom G5 mobile User Manual

Receiver
The receiver alerts you with an initial vibration for calibration prompts. If not cleared, you
receive a vibrate/beep every five minutes until confirmed.

7.6 Preparing for Calibration

Your sensor depends on you to help make its sensor glucose readings accurate. If you don't
prepare properly for the calibration, your sensor may not provide you with the most accurate
sensor glucose readings.
Eight Steps to Successful Calibration:
Do:
1. Wash and dry your hands before staking a fingerstick measurement.
2. Always use the same meter you routinely use to measure your blood glucose.
a. Blood glucose meter and strip accuracy vary between meter brands.
b. Switching within a session might cause sensor glucose readings to be
less accurate.
3. Follow meter's instructions exactly when taking your fingerstick measurement.
4. Verify test strips are current and, if required, coded correctly with meter.
5. Check: Is Bluetooth is active?
6. Use fingerstick BG values only.
a. Other sites are not as accurate.
b. Must enter within five minutes of taking BG meter value.
c. Enter exact BG value from your meter for each calibration.
Don't:
7. Don't take acetaminophen containing medication during your session (e.g., Tylenol).
a. See your healthcare professional to better understand how long acetaminophen
is active in your body.
8. Don't calibrate if your BG values are under 40 mg/dL or over 400 mg/dL.
a. If BG value is outside of this range, receiver doesn't understand these values and
won't calibrate.
i. You must wait until your blood glucose is in the range to calibrate.
Be safe—if blood glucose is low, first treat low blood sugar, and then calibrate.

7.7 Ready? Set? Calibrate!

You've followed the eight steps above, have a valid BG value from your meter, and your
display device keeps alerting you: Calibrate! Calibrate! Calibrate!
