Reading the sensor glucose graphs
NOTE: If your graphs say DEMO in the upper left corner of your screen, you must turn off the SENSOR
DEMO mode to see your actual graphs (see the Using the Sensor Demo section in the Sensor features chapter).
Your pump shows an updated, continuous glucose measurement. This measurement is generated by data sent
from the sensor to the transmitter, and then to the pump every five minutes. The pump converts these
measurements to glucose graphs that include the following information:
• The most recent sensor glucose measurement or the reason that one is not displayed.
• The historical sensor glucose measurements or the reason that one is not displayed for the last 3,
6, 12 or 24 hours.
• Arrows that show the relative rate at which the most recent sensor glucose levels have risen or
fallen.
The following conditions can prevent a continuous sensor glucose measurement from being taken:
• A Lost Sensor alert.
• A Sensor Error alert.
• A Change Sensor alert.
• A Cal Error alert.
• Find Lost Sensor (15 minutes).
• Weak signal.
• Reconnect old sensor (two hours).
• A meter BG entry is needed for calibration.
Two other conditions also prevent a continuous SG measurement and generate a WARM UP message on your
sensor glucose graphs:
• You started a new sensor, and it has entered a two-hour initialization. The sensor is not ready to take
glucose measurements.
• You entered a BG for calibration, and your pump is waiting to receive the first valid SG value.
