meter value is very different from your G6 reading.
WARNING

to make treatment decisions until you calibrate your G6.
Why: Calibrating keeps your G6 accurate.
Consequences: You could have a severe low or high glucose event.

7.3 Prepare to Calibrate

Your G6 depends on you to help make its readings accurate. If you don't prepare properly for calibration, your sensor may become
inaccurate.
Calibration Tips
Hands:
• Clean: Wash and dry your hands before fingersticks. Use soap and water, not gel cleaners. Poorly washed hands are the cause of many
meter errors.
• Finger: Use fingerstick meter values only. Other sites are less accurate.
Meter:
• Test strips: Verify they're current and, if required, coded correctly with meter.
• Consistent meter: Always use the meter you routinely use to measure your BG. Meter and strip accuracy vary between meter brands.
Switching within a session might cause readings to be less accurate. Also make sure meter date and time match your display device
date and time.
• Instructions: Follow meter use and maintenance instructions exactly.
• Use meter value: Only use your meter for calibrations; never enter values from your G6.
G6:
• Bluetooth
: Make sure it's active.
• Trend arrow(s) straight up or down: Don't calibrate when your trend arrow(s) points straight up or down; this means your reading is
changing more than 2 mg/dL per minute. Why? Because by the time you take a meter value and enter it into your G6, your BG will have
changed.
• Timing: Must enter within 5 minutes of taking meter value.
• Accuracy: Enter exact meter value for each calibration.
Be safe — if BG is low, first treat, then calibrate.
WARNING
Do: Use fingertips to calibrate from your meter.
