Startup Calibration - Dexcom G4 Platinum User Manual

PRECAUTION
To calibrate the system, do enter the exact blood
glucose value that your blood glucose meter displays
within 5 minutes of a carefully performed blood glucose
measurement. Do not enter sensor glucose readings
for calibration. Entering incorrect blood glucose values,
blood glucose values obtained more than 5 minutes
before entry, or sensor glucose readings might affect
sensor accuracy and could result in you missing severe
hypoglycemia (low blood glucose) or hyperglycemia (high
blood glucose) events.

7.3 STARTUP CALIBRATION

Two hours after you start the sensor session
(see Chapter 6, Section 6.7, Starting a
Sensor Session) the receiver tells you
that you need to calibrate by showing the
startup calibration prompt. This means you
need to calibrate with 2 separate blood
glucose values from your meter. You
will not see sensor glucose readings
until the receiver accepts the blood
glucose values.
1. When you see this screen, press the
a. The startup calibration symbol will stay at the top of the trend graph
until you calibrate.
b. The system will re-alert you every 15 minutes until you enter the
blood glucose values.
c. If you do not clear the prompt, the system will re-alert you every
5 minutes.
