BEFORE YOU BEGIN
Important Information
Severe dehydration and excessive water loss may cause readings
which are lower than actual values. If you believe you are suffering
from severe dehydration, consult a healthcare professional
immediately.
If your test results are lower or higher than usual, and you do not
have any symptoms of illness, first repeat the test. If you have
symptoms or continue to get results which are higher or lower than
usual, follow the treatment advice of your healthcare professional.
Use only fresh whole blood samples to test your lactate. Using
other substances will lead to incorrect results.

QC testing with the control solution
You can switch between each mode by: In the measuring mode, after
a test strip is inserted, press ▲or ▼to select a suitable measuring
mode when the meter displays the list. Press Mand proceed with a
lactate testing.
BEFORE TESTING
Calibration
You must calibrate the meter every time you begin to use a new box
of lactate test strips by setting the meter with the correct code. Test
results may be inaccurate if the code number displayed on the
monitor does not match the number printed on your test strip vial or
individual foil packet.

7
How to Code Your Meter
1. Insert the code chip when the monitor is off. Wait until the number
appears on the display. (b)
NOTE:
Make sure the number on display, code chip, and test strip vial (or individual
foil package) are the same.
2. Remove the code chip, the display will show “OFF”. This tells you
that the meter has been updated and is ready for measurement.
Checking the Code Number
You need to make sure that the code number displayed on the meter
matches the number on the test strip vial or box of foil package
before you proceed (b). If it matches, you can proceed with your test.
If the codes do not match, please stop testing and contact Customer
Service for help.
NOTICE:
The code number on the display from picture (b) is only for your
reference, it may not be an actual code for this meter.
WARNING:
It is important to make sure that the LCD displayed code is the same as the
code on the test strip vial or box of foil package before testing. Failure to do
so will get inaccurate results.
If the LCD displayed code is not the same as the code on the test strip vial
or box of foil package, and the code number cannot be updated, please
contact Customer Service for assistance.

QUALITY CONTROL TESTING
When Should the Control Solution Test be
Performed?
if it is mandatory following the local regulations in your country,
if you suspect the meter or test strips are not working properly,
if your lactate test results are not consistent with how you feel, or if
you think the results are not accurate,
to practice the testing process, or
if you have dropped or think you may have damaged the meter.
Test strips (e), control solutions (f), lancing device (g) or sterile
lancets may not be included in the kit (please check the contents on
your product box). They can be purchased separately. Please make
sure you have those items needed for a lactate test beforehand.
Performing a Control Solution Test
To perform a control solution test, you will need: (d), (e) and (f).
When the meter is off, you can enter the measuring mode by
two ways:
1. Insert the test strip to turn on the meter
Insert the test strip into the meter. Wait for the meter to display
the initiating animation. Or,
Press M to turn on the meter
Select the measuring mode. Press M to enter. Insert a test strip
when the meter displays test strip inserting animation. Wait for
the meter to display the initiating animation.

9
2. Select Q.C. and press M to perform this test in the control
solution measuring mode.
Warning:
When doing the control solution test, you have to mark it so that the test
results will NOT mix with the lactate TEST RESULTS stored in the memory.
Failure to do so will mix up the lactate test results with the control solution
test results in memory.
3. Apply control solution (h)
Shake the control solution vial thoroughly before use. Squeeze
out the first drop and wipe it off, then squeeze out another drop
and place it on the tip of the vial cap. Hold the meter to move the
absorbent hole of the test strip to touch the drop. Once the
confirmation window fills completely, the meter will begin
counting down.
NOTE:
To avoid contaminating the control solution, do not directly apply control
solution onto a strip.
4. Read and compare the result
After counting down to 0, the control solution test result will
appear on the display. Compare this result with the range printed
on the test strip box or test strip vial and it should fall within this
range. If not, please read the instructions again and repeat the
control solution test.
NOTE:
The control solution range printed on the test strip box is for control solution
use only. It is not a recommended range for your lactate level.
See the MAINTENANCE section for important information about your
control solutions.

10
TESTING WITH BLOOD SAMPLE
Warning:
To reduce the chance of infection:
Never share a lancet or the lancing device.
Always use a new, sterile lancet. Lancets are for single use only.
Avoid getting hand lotion, oils, dirt, or debris in or on the lancets and the
lancing device.
Preparing the Lancing Device for Blood Testing
Please follow the instructions in the lancing device insert for
collecting a blood sample.
Preparing the Puncture Site
Stimulating blood perfusion by rubbing the puncture site before blood
extraction has a significant influence on the lactate value obtained.
Blood from a site that has not been rubbed exhibits a measurably
different lactate concentration than blood from the finger. When the
puncture site was rubbed prior to blood extraction, the difference was
significantly reduced.
Please follow the suggestions below before obtaining a drop of
blood:
Wash and dry your hands before starting.
Select the puncture site either at fingertips.
Rub the puncture site for about 20 seconds before penetration.
Clean the puncture site using cotton moistened with 70% alcohol
and let it air dry.
Fingertip testing (i)
Press the lancing device’s tip firmly against the lower side of your
fingertip. Press the release button to prick your finger, then a click
indicates that the puncture is complete.

11
NOTE:
Alcohol swabs with 70% alcohol can be purchased in pharmacy.
Choose a different spot each time you test. Repeated punctures at the same
spot may cause soreness and calluses.
Performing a Lactate Test
To perform a lactate test, you will need: (d), (f) and (g).
1. Insert a test strip to turn on the meter
The meter displays the initiating animation.
2. Select general mode by pressing ▲or ▼.
Press Mto perform this test.
3. Obtaining a blood sample (j)
Use the pre-set lancing device to puncture the desired site. The
size of the drop should be at least as 0.8 microliter (μL) of volume.
Gently squeeze the punctured area to obtain another drop of
blood. Be careful NOT to smear the blood sample.
4. Apply the sample (k)
Gently apply the drop of blood to the absorbent hole of the test
strip at a tilted angle. Confirmation window should be completely
filled if enough blood sample has been applied. Do NOT remove
your finger until you hear a beep sound.
NOTE:
Do not press the punctured site against the test strip or try to smear the
blood.
If you do not apply a blood sample to the test strip within 3 minutes, the
meter will automatically turn off. You must remove and reinsert the test strip
to start a new test.
The confirmation window should be filled with blood before the meter begins
to count down. NEVER try to add more blood to the test strip after the drop
of blood has moved away. Discard the used test strip and retest with a
new one.
If you have trouble filling the confirmation window, please contact your
health care professional or the local customer service for assistance.

12
5. Read Your Result
The result of your lactate test will appear after the meter counts
down to 0. The lactate result will be stored in the memory
automatically.
6. Eject the used test strip (l)
Eject the test strip by pushing the eject button on the top. The
meter will switch itself off automatically.
Always follow the instructions in the lancing device insert when
removing the lancet.
WARNING:
The used lancet and test strip may be biohazardous. Please discard them
carefully according to your local regulations.
