Abbott FreeStyle Libre 2 Manual

Applying Your Sensor
Step
Action
1
Apply Sensors only on the back of your upper
arm. If placed in other areas, the Sensor may
not function properly and could give inaccurate
readings. Avoid areas with scars, moles, stretch
marks, or lumps.
Select an area of skin that generally stays at
during your normal daily activities (no bending
or folding). Choose a site that is at least 2.5 cm
(1 inch) away from an insulin injection site. To
prevent discomfort or skin irritation, you should
select a dierent site other than the one most
recently used.
2
Wash application site using a plain soap, dry, and
then clean with an alcohol wipe. This will help
remove any oily residue that may prevent the
Sensor from sticking properly. Allow site to air
dry before proceeding.
Note: The area MUST be clean and dry, or the
Sensor may not stick to the site.
Using Your Sensor
CAUTION:
• The Sensor Pack and Sensor Applicator are packaged as a
set (separately from the Reader) and have the same Sensor
code. Check that the Sensor codes match
before using your Sensor Pack and Sensor
Applicator. Sensor Packs and Sensor
Applicators with the same Sensor code
should be used together or your Sensor
glucose readings may be incorrect.
• Intense exercise may cause your Sensor
to loosen due to sweat or movement of the
Sensor. If your Sensor comes loose or if the Sensor tip
is coming out of your skin, you may get no readings or
unreliable readings, which may not match how you feel.
Remove and replace your Sensor if it starts to loosen and
follow the instructions to select an appropriate application
site. Do not attempt to reinsert the Sensor. Contact
Customer Service if your Sensor becomes loose or falls o
before the end of the wear period.
