1.2 SEVEN SENSOR OVERVIEW
e Sensor is a device that continuously measures your glucose levels. You will use a
Blood Glucose (BG) meter to calibrate the readings measured by the Sensor. e glucose
levels measured by the Sensor are sent by a wireless, low-powered, radio frequency (RF)
to the Receiver every 5 minutes for up to 7 days.
e Sensor consists of an Applicator (needle, Sensor, plastic housing), Sensor Probe,
and Sensor Pod. You will insert the Sensor Probe just beneath the skin (subcutaneous
tissue) of your abdomen (belly) using a small needle (26-Gauge) inside the Applicator.
e needle is inserted about ½ inch beneath your skin and carries the Sensor Probe with
it. After you insert the needle and Sensor Probe, you will pull the needle back into the
Applicator leaving the Sensor Probe behind to continuously measure your glucose levels.
e Applicator is then removed from the Sensor Pod and should be thrown away. You
should save the Safety Lock/ Transmitter Release to remove the Transmitter at the end of
a continuous monitoring session.
e Sensor Probe lies ½ inch underneath your skin and continuously measures your
glucose levels for up to 7 days. e Sensor Pod and Transmitter (once snapped in) remain
on your abdomen for the entire wear period. e insertion site is very similar to an insulin
pump infusion site.
