Important Information
• The CareSens LINK blood glucose monitoring system is intended for
self-testing outside the body (in vitro diagnostic use).
• The glucose in the blood sample mixes with special chemicals on the
test strip where to produce a small electrical current. The CareSens
LINK meter detects this electrical current and measures the amount
of glucose in the blood sample.
• The CareSens LINK blood glucose meter is designed to minimize
code related errors in monitoring by using the no-coding function.
• The CareSens LINK blood glucose meter should be used only with
the CareSens LINK strip.
• The average hematocrit range is between 30 and 50%. However,
people with severe anemia, pregnant women and newborns may
have higher hematocrit and this can affect the test results.
• Very high (60% or more) or very low (20% or less) hematocrit can
lead to incorrect test results.
• A glucose value of less than 70 mg/dL (3.9 mmol/L) may indicate
hypoglycemia and a value of more than 240 mg/dL (13.3 mmol/L)
may indicate hyperglycemia.
If you need assistance, please contact your authorized i-SENS sales
representative or visit www.i-sens.com for more information.

Checking the System
You may check your meter and test strips using the
CareSens Control Solution.
The CareSens Control Solution contains a known amount of
glucose and is used to check that the meter and the test strips
are working properly. The test strip vials have CareSens
Control Solution ranges printed on their labels. Compare
the result displayed on the meter to the CareSens Control
Solution range printed on the test strip vial.
Before using a new meter or a new vial of test strips, conduct
a control solution test following the procedure on page 20.
•Use only the CareSens Control Solution.
• Check the expiration dates printed on the vial. When you first open
a control solution vial, record the discard date (date opened plus
three months in the space provided on the label).
• Make sure your meter, test strips, and control solution are at room
temperature before testing. Control Solution tests must be done at
room temperature (20 ~ 25˚C, 68 ~ 77˚F).
• Before using the control solution, shake the vial, discard the first
few drops and wipe the tip clean.
• Close the control solution vial tightly and store at a temperature of
8 ~ 30˚C (46 ~ 86˚F).
Notes:
•
When using the meter for the first time
•
Whenever you open a new vial of test strips
•
If the meter or test strips do not function properly
•
If your symptoms are inconsistent with the blood glucose test
results and you feel that the meter or test strips are not working
properly
•
If you drop or damage the meter
Do a solution test:
Step 11
Discard the used test strip by pushing the strip ejection button on
the right side of the meter as shown in the picture on the right to
a proper disposal container. The meter will turn off automatically
in three seconds after the test strip has been removed.
When the Bluetooth mode is activated, follow the next step (Step
12)
Step 12
If the Bluetooth mode has been activated, ‘bT’ will appear on the
display and try to connect with a Bluetooth device when the test
strip has been removed.
Depending on the user’s Bluetooth settings PIN Code input may
be necessary in order to register the external Bluetooth device.
In this case, type in ‘0000’ in the input box. When the measured
glucose value has been transmitted via Bluetooth, the transmitted
data in the meter will be automatically deleted and the meter will
turn itself off.
In case, the measured glucose value has NOT been transmitted
even with the Bluetooth activated, ‘con’ and ‘check’ icon will
appear on the display. When measuring the glucose level at a
Bluetooth ready environment later, previous values stored in the
meter and the most recent value will be transmitted altogether.
Note
Shake the CareSens Control Solution
vial before each test. Remove the cap
and squeeze the vial to discard the
first drop. Then wipe the tip with a
clean tissue or cloth. After the
symbol appears on the
display, apply the solution to the narrow edge of the test strip until the
meter beeps. Make sure the confirmation window fills completely.
www.i-sens.com
20
Step 1
Insert a test strip into the meter’s strip port, with
the contact bars facing upwards.
Gently push the test strip into the port until the
meter beeps. Be careful not to break the strip
while pushing it in.
The icon will be displayed on the screen.
Step 2
Control Solution Testing
The meter may switch off, if the blood sample is not applied within
2 minutes of the
icon appearing on the screen. If the meter
turns off, remove the strip, reinsert, and start from step 1.
Note
If all the results you get on testing three times continuously are
within the range printed on the test strip, the meter and test
strips are working properly and you may use them for your blood
glucose test.
Caution
www.i-sens.com
21
Step 3
A test result will appear after the meter counts
down from 5 to 1.
After your control solution result appears on
the display, press 󰦜 for 3 seconds till the
‘check’ icon appears on the display. When the
‘check’ icon is displayed, the result is not stored
in the meter’s memory and is not included in
the 14-day averages.
Step 4
Compare the result displayed on the meter
to the range printed on the test strip vial. The
result should fall within that range.
Used strips should be discarded safely in
disposable containers.
• If the results you get are not within this range, the meter and
test strip may not work properly. Then, stop using the meter
and contact the nearest i-SENS representative.
• The range printed on the test strip vial is for the CareSens
Control Solution only. It does not have any connection to your
blood glucose level.
Caution
www.i-sens.com
22
Repeat the control test if the test result falls outside the range printed
on label of the test strip vial. Out of range results may occur due to the
following factors:
Comparing the Control Solution Test Results
•When the control solution vial was not shaken well,
•When the control solution is past its expiration date or is
contaminated,
•When the meter, the strip or the control solution were exposed to
high or low temperatures,
•When the first few drops of the control solution were not discarded
or the tip of the vial was not wiped clean,
•When the test strip is past its expiration date,
•When the meter is not functioning properly.
The CareSens Control Solution can be purchased separately.
Please contact your authorized i-SENS sales representative.
Note

Using the Lancing Device
You will need a lancing device in order to collect a blood sample.
You may use the lancing device contained in the CareSens LINK
Blood Glucose Monitoring System or any other medically approved
lancing device.
• The lancing device should be used by one individual and communal
use is strongly discouraged.
• Use a soft cloth or tissue to wipe the lancing device. If necessary, a
small amount of alcohol on a soft cloth or tissue may be used.
To avoid infection when drawing a sample, use a lancet only one
time, and:
• Do not use a lancet that has been used by others.
• Always use a new sterile lancet.
• Keep the lancing device clean.
Caution
Repeated puncturing at the same sample site may cause pain or
skin calluses. Choose a different site each time you test.

Usually, when someone tests their glucose, they take the blood
sample from the tip of the finger. However, since there are
many nerve endings distributed there, it is quite painful. When
doing a glucose test, using different parts of the body such as
the arms, palms, thighs, and calves can reduce the pain during
testing. This method of testing with different parts of the body is
called Alternative Site Testing. While AST may reduce the pain
during testing, it may not be simple for everyone and the following
precautions should be observed during testing.
Alternative Site for Testing
What is AST(Alternative Site Testing)?
Alternative Site Testing
www.i-sens.com
31
•
When the glucose levels are rapidly increasing
during the two hours after a meal or exercise
•
When sick or when glucose levels seem quite lower
than test value
•
When hypoglycemia is not well recognized
•
When insulin has the biggest effect
•
2 hours after an insulin injection
Situations requiring fingertip test
Acceptable situations for AST
• Fasting period
• Before a meal
• Before sleeping
Please understand the following things before testing outside of
the fingertip (arms, thighs, calves).
The capillary blood of the fingertip shows the change in glucose
more rapidly than AST. Therefore, the test results from the
fingertip test and AST may differ. This is because things such as
lifestyle and ingested food have an effect on glucose levels.
Things to know when using AST
www.i-sens.com
32
•Do not ignore the symptoms of hyperglycemia or hypoglycemia.
•When the results of the test do not reflect one’s opinion, retest
using the fingertip test.
If the test results do not reflect one’s opinion, please consult a
doctor.
• Do not rely on the AST results for changing one’s treatment
method.
• The amount glucose in alternative sites differs from person to
person.
•Before using AST, please consult your regular physician.
AST Precautions
Results from alternative site and fingertip samples may appear
differently as there is a time lag for the glucose levels to reach
the same value. Use a fingertip for drawing if you suffer from
hypoglycemia or have experienced hypoglycemic shock or
symptoms.
Note
If the sample drop of blood runs or spreads due to contact with
hair or with a line in you palm, do not use that sample.
Try puncturing again in a smoother area.
Note

Hi and Lo Messages
The meter displays results between 20 ~
600 mg/dL (1.1 ~ 33.3 mmol/L). The Hi icon
appears when the blood glucose level is more
than 600 mg/dL (33.3 mmol/L) and indicates
hyperglycemia.
If the Hi icon is displayed again on re-testing,
please contact your healthcare professional
immediately.
Lo Message
The Lo icon appears when the result is less
than 20 mg/dL (1.1 mmol/L) and indicates
