The steps to using your sensor
Once you’ve downloaded the FreeStyle Libre 3 app‡ or FreeStyle Libre 2 app§ or obtained a reader device, follow these steps to use your sensor:
Step 1: Preparing your skin
Applying your new sensor is a lot easier than you might think. To begin, select an area on the back of your upper arm and:
Wash the area using plain soap and water.
Pat the area dry with a clean towel.
Clean the area with alcohol wipe and allow it to air dry.
Step 2: Applying your sensor
Once you’ve prepared the back of your upper arm, apply the sensor using either the two-piece or the one-piece applicator:
Place the sensor applicator over the prepared site and push down firmly.
The sensor should now be attached to your skin.
Secure by pressing down gently with your finger around the edge.
Step 3: Activating your sensor with your reader or app
Follow these steps to activate your sensor with your reader or app†, so you can track your glucose levels:
Press “Scan New Sensor” on your reader or smartphone.
Hold your device near the sensor and slowly scan it.
You will hear a beep or feel a vibration upon activation.
The sensor can be used to check your glucose after 60 minutes.
Step 4: Removing and replacing your sensor
It’s easy to remove and replace your sensor—follow the steps below to learn how:
Your sensor is designed to stay on for up to 15 days. When it's time to remove it, pull up the adhesive edge that keeps the sensor attached to your skin, then slowly peel from your skin in a single motion.
When replacing your sensor, remember to choose a different spot on the back of your upper arm to apply the new sensor. This will help avoid skin irritation.
Read our sensor application guide to learn about some optional productsII that can be helpful for removing your sensor.
Useful tips for sensor wear
Applying your sensor
Sensors stick better when you wash, clean and dry your skin before application.
Wash: Only use non-moisturising, fragrance-free soaps to wash the area where you’ll apply the sensor.
Clean: Use the alcohol wipe provided in the sensor kit to remove any oily residue on the skin.
Dry: Allow your skin to fully dry before applying the sensor.
Before you apply the sensor:
Be sure to choose an approved application site − the back of your upper arm
Do not use body lotion or cream where you’ll apply the sensor as it may leave an oily residue on your skin
Do shave any excess arm hair as it can get caught between the sensor adhesive and skin
Keeping your sensor in place
Easy does it: Be careful not to catch your sensor on a doorway, car door, seat belt, or furniture edges.
Pat dry: After a shower or swim, take extra care when towelling off to avoid catching or pulling off your sensor.
Dress for success: Try to give your sensor room by wearing loose-fitting clothing and lightweight material.
Protect it during contact sports and heavy exercise. Be sure to select a site on the back of your upper arm that will minimize the risk of it coming off, and consider using an overbandage and/or any of the items on the previous page.
Slow down : When dressing or undressing, be careful that you don’t catch your undergarments on the sensor.
Hands off : Avoid playing with or pulling the sensor while wearing it.Cautions
