How to apply the sensor
Choosing the site
- Select an area on the back of your upper arm, avoiding areas with moles, scarring, or recent insulin injections¶
- Select a different site than the one most recently used
Preparing your skin
Preparing your skin is an important step toward ensuring adhesion. Our sensor adhesion guide in our Support section suggests solutions to help overcome common skin surface conditions.
Applying the sensor
The sensor pack and sensor applicator are packaged as a set (separately from the reader).#
Open the sensor pack by peeling off the lid completely. Unscrew the cap from the sensor applicator and set the cap aside.**
Line up the dark mark on the sensor applicator with the dark mark on the sensor pack. On a hard surface press down firmly on the sensor applicator until it comes to a stop.††
Place the sensor applicator over the prepared site and push down firmly until the Sensor is in place.‡‡
Make sure the sensor is secure after application. Put the cap back on the sensor applicator. Discard the used sensor pack and sensor applicator per local regulations.§§

† Based on the sensor being replaced once every 10 days, and scanned at least once every 8 hours.
‡ The reader can capture data from the sensor when it is within 1 cm to 4 cm of the sensor.
§ Sensor is water resistant in up to 1 meter (3 feet) of water. Do not immerse longer than 30 minutes.
¶ Choose a site that is at least 2.5 cm (1 inch) away from an insulin injection site.
CAUTION: # The Sensor Pack and Sensor Applicator have a the same sensor code. The sensor codes should be checked to match before using Sensor Pack and Sensor Applicator. Do not use Sensor Packs and Sensor Applicators with different Sensor codes together as this will result in incorrect glucose readings. ** Do NOT use if the Sensor Pack or the Sensor Applicator seem to be damaged or already opened. Do NOT use if past expiration date.
†† The Sensor Applicator now contains a needle. Do not touch inside the Sensor Applicator or put it back into the Sensor Pack.
‡‡ Do not push down on the Sensor Applicator until placed over prepared site to prevent unintended results or injury.
§§ Applying the Sensor may cause bruising or bleeding. If there is bleeding that does not stop, remove the Sensor, and apply a new one at a different site.
