3 Steps to Apply Sensor
Sensors stick better when you wash, clean, and dry your arm before application.
01 Wash, Clean, and Dry
Select a site on the back of your upper arm
that stays flat during normal activity. Clean
skin with non-moisturizing, fragrance-
free soap and water. Use an alcohol wipe
to disinfect the skin and let air dry before
proceeding. Tip: Do not use moisturizer
where you apply the sensor.
02 Prep Applicator
Open sensor by peeling back the lid.
Unscrew cap from the sensor applicator.
Line up marks on the sensor applicator.
Press down firmly and then lift.
The FreeStyle Libre 2 system is designed to stay on for up to 14 days.
• Secure sensor by pressing it down and running your finger along the sensor adhesive.
• Apply sensor to dierent sites each time to avoid irritating your skin.
• Avoid placing sensor on moles, scars, stretch marks, and lumps. Shave hair on arm,
if necessary.
03 Apply
Apply the sensor to the back of your
upper arm by pressing firmly. Listen for
the click. Wait 30 seconds and pull back
slowly, leaving the sensor on the skin.
Tips to Help Keep
Your Sensor in Place
Some people use the following products for extra stickiness and protection:*
Torbot Skin Tac™
Hypoallergenic and
latex-free “tacky” skin barrier
Skin-Prep™ Protective
Barrier Wipe
Protective liquid dressing that
allows skin to breathe so tapes
and films adhere better
Mastisol® Liquid
Adhesive
Clear, non-irritating, non-
water-soluble liquid adhesive

Parent Tip
Because kids have smaller arms, it can be challenging to find a new sensor
application spot. Make sure to rotate the site to allow skin to fully heal.
Switching arms each time can help.
Parent Tip
Experiment to find extra stickiness products that work for your child.
Try an over-bandage for active kids.

4 Steps to Activate Sensor Scanning Tips
Follow these steps to be ready to get readings in just one hour. The more you scan, the more you know about your diabetes.
01 Turn on FreeStyle Libre 2 Reader
Hold your reader within 1.5 inches
of your sensor to scan right through
your clothes.*
Scan frequently
Remember to scan at least once every 8 hours to
avoid gaps in your daily graph. The more you scan,
the more complete picture you and your doctor
have to help manage your diabetes.
03 Scan with Reader
04 Let Sensor Warm Up for One Hour
Then you can start getting glucose readings.

Sensor Glucose Screen
This screen shows your current glucose reading and a
trend arrow. With trend arrows, you can monitor the
direction your glucose is heading. Tip: Trend arrows
don’t always appear (see Check Glucose Symbol below).
This symbol may appear if:
• Your sensor glucose is rapidly changing
• Your sensor glucose is low or going low
• LO or HI appears on the screen
• No trend arrow or glucose number appears
on screen
• You are in the first 12 hours of sensor wear
Current reading What trend arrows mean:
110 Glucose is rising quickly
(more than 2 mg/dL per minute)
110 Glucose is rising
(between 1 and 2 mg/dL per minute)
110 Glucose is falling
(between 1 and 2 mg/dL per minute)
110 Glucose is falling quickly
(more than 2 mg/dL per minute)
A1c is useful because it measures your average glucose level over the past three months.
It’s helpful to look back at how you are managing your diabetes. But a good A1c doesn’t
mean your glucose is in control today. It doesn’t show your highs and lows or how your
blood glucose levels change throughout the day. This is where Time in Range can help.
If you see the symbol, do a
blood glucose test before
making treatment decisions.
READER SYMBOL

Check Glucose Symbol
Time in Range is the percentage of time you stay
within your target glucose range. You work with
your healthcare provider to determine a target
range goal. Your progress is then tracked in a
Time In Target report.

Use Alarms for Extra Safety
The FreeStyle Libre 2 system has optional, real-time glucose alarms* to help keep
you safe, even at night. Alarms are on by default and can be customized. Alarms
feature preset tones, a vibration option, and adjustable volume. To receive alarms,
your reader should be within 20 feet of you and unobstructed at all times. If you
are out of range, you may not receive glucose alarms.
Customize Alarms
Alarms are easyto set based on your target glucose goals.
Reference: 1. Data on file. Abbott Diabetes Care. 2. Please see the FreeStyle Libre 2 User’s Manual for complete instructions. 3. 70 mg/dL is the default Low
Glucose Alarm level and can be set between 60–100 mg/dL. 240 mg/dL is the default High Glucose Alarm level and can be set between 120–400 mg/dL.
*Notifications will only be received when alarms are turned on and the sensor is within 20 feet of the reading device.

Remove & Replace Sensor
Replace Sensor
Remember to choose a dierent spot on the back
of your upper arm to apply the new sensor. This
will help avoid skin irritation. See page 4 for
application instructions.
Sensor Disposal: The sensor should be disposed of in accordance with all applicable local
regulations related to the disposal of electronic equipment, batteries, sharps, and materials
potentially exposed to body fluids. Contact Customer Service for more information.
The sensor is designed to stay on for up to 14 days. Here’s how to remove, replace,
and properly dispose of system components.
Tips for Wearing Your Sensor
Clothing:* Scan right through
your clothes. Be careful when
dressing to avoid disturbing
the sensor.
Showering, bathing, and
swimming:†Sensor is water-
resistant. Do not submerge more
than 3 feet or keep under water
longer than 30 minutes at a time.
Gently pat dry after getting it wet.
Exercising: Use skin adhesive
if sweating loosens sensor.
Try an over-bandage if
playing contact sports.
Traveling: System is safe to
use while on an aircraft. Do not
expose the sensor to airport
full-body scanners. Request
another type of screening to
avoid removing your sensor.
Medical procedures: Notify
your healthcare provider and
remove your sensor when
necessary. Exposing the sensor
to MRI, CT scan, diathermy, or
X-ray may cause damage and
incorrect readings.
Some good-to-know ideas about using CGM throughout your day.
*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.

Dierent and Accurate
CGM readings are taken
from interstitial fluid, a
thin layer of fluid that
surrounds the cells below
your skin.
Blood glucose readings
are taken from blood
with fingersticks.
FPO
The CGM Dierence
There are times when your CGM and BGM readings may be dierent.
CGM measures interstitial fluid glucose not blood glucose.
CGM systems give you a look at where you were, where you are, and where you’re headed.
You can trust your sensor glucose numbers and can feel confident in your results to
make treatment decisions. The FreeStyle Libre 2 system is approved for insulin dosing
without fingersticks.*
CGM is dierent from blood glucose monitors (BGM) and proven to be accurate,
with fewer fingersticks.*
These include when:
• Your glucose is changing rapidly; scan
shows a trend arrow (see diagram, page 11)
• Your fingers were not washed before you
performed a fingerstick test
• You took more than 500 mg of vitamin C
(ascorbic acid)
• Blood glucose strips were expired
or contaminated
• The fingerstick check and sensor scan
were not performed at the same time
• It is the first day wearing your sensor
• The sensor was bumped and is not firmly
attached to the back of your upper arm

*Fingersticks are required if your glucose alarms and readings do not match symptoms or when you see Check Blood Glucose symbol during the first 12 hours.*Fingersticks are required for treatment decisions when you see Check Blood Glucose symbol, when symptoms do not match system readings, when you suspect
readings may be inaccurate, or when you experience symptoms that may be due to high or low blood glucose.
Reference: 1. FreeStyle Libre 2 User’s Manual.
Dierence Between CGM and BGM Readings
CGM and BGM
readings are often
similar when stable.
Rapidly changing levels, like after a meal or exercise, can
cause a lag between your CGM and BGM readings.
For most people, the lag
is about 5–10 minutes.
That’s normal.
Glucose enters your blood stream first
before it enters the interstitial fluid.
