Chapter 7: Calibrate
7.3 Prepare to Calibrate
When using a glucose meter to calibrate, if you don’t prepare properly, your sensor may
become inaccurate.
Calibration Tips
Hands:
• Clean: Thoroughly 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.
• Same meter: Always use the same meter during your sensor session. Meter and
strip accuracy vary between meter brands. Switching within a session might cause
G6 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: This means your reading is changing more than
2 mg/dL per minute. Because of this, enter your meter value immediately after
taking a fingerstick.
• Timing: Enter your meter value within 5 minutes of taking a fingerstick.
• Accuracy: Enter exact meter value for each calibration.
Be safe – if BG is low, first treat, then if you want, align your sensor to your meter by
calibrating.
