7.5 OTHER REASONS YOU MAY NEED TO
CALIBRATE
You may need to calibrate when your system did not accept the last
calibration or your blood glucose value is very different from the sensor
glucose reading.
When you see this calibration prompt it means
it is time to calibrate with a single blood
glucose value.
Take 1 blood glucose measurement with
your meter, and enter the blood glucose into
the receiver. If this screen reappears soon,
see Chapter 13, Section 13.2.1, Types of
Calibration Prompts.
These screens show calibration errors (see Chapter 13, Section 13.3,
Calibration Error Troubleshooting).
