7.2 HOW TO CALIBRATE
You must enter the exact blood glucose value from the meter for each
calibration. Blood glucose values used for calibration must be between
40-400 mg/dL and must have been taken within the past 5 minutes.
• In real-time mode, make sure either a sensor glucose reading or a
calibration needed symbol shows at the top of the trend graph in the
status area before calibrating. In blinded mode, make sure either “- - -”
or a calibration needed symbol shows at the top of the trend graph
in the status area before calibrating.
• The sensor can be calibrated if the meter glucose is 40 mg/dL or
above. For safety reasons, if the blood glucose is low, first treat the low
blood sugar.
• Always make sure the antenna symbol
is in the upper left corner of
the trend graph before you enter blood glucose values for calibration.
• Always use the same meter to calibrate that you routinely use to
measure the blood glucose. Do not switch the meter in the middle of a
sensor session. Blood glucose meter and strip accuracy vary between
blood glucose meter brands.
• The accuracy of the blood glucose meter value used for calibration
may affect the accuracy of sensor glucose readings.
WARNING
Calibrate at least once every 12 hours. Calibrating less
often than every 12 hours might cause sensor glucose
readings to be inaccurate, and you might miss a low or
high blood glucose value.
