2 Performing a test
2.1 Preparing for a test
Remove a sensor from the container. Make
sure you do not touch the opening for the
blood sample 1. As soon as you have taken
it out, insert the sensor into the measuring
device opening in the direction of the arrow
until you can feel resistance 2. The contacts
must be facing up.
3
The display will briefly show the code which
is currently configured. A blinking drop
symbol will then be displayed to indicate
that the measuring device is ready to take a
measurement. The ambient temperature of the
measuring device will be displayed beneath
the info line 3.
ATTENTION
Before you use a sensor from a new sensor
container, you must check that the code on the
label is the same as the code currently configured
in the device. If the code does not match, then it
must be configured again in the device.
2

11
ATTENTION
The sensor and the measuring device must
be at the same temperature when performing
a test. If you take the sensor container out
of the fridge, you must wait for at least
20minutes until the sensor container has
reached the ambient temperature before you
open the container. If you take the sensor
container out of the freezer, you must wait
for at least 2 hours until the sensor container
has reached the ambient temperature. Only
remove sensors to be used immediately
for testing purposes. Reseal the container
immediately after removing the sensor. Never
leave the container open.
2.2 Blood collection and test
Wash your fingers or earlobes with clean
water at the puncture site. You can use the
spray bottle supplied with the accessories for
this purpose. Dry the puncture site. In order
to take a capillary blood sample, puncture the
site using a suitable lancet.
Wipe away the first droplet of blood. Apply
gentle pressure to the puncture site. The
second droplet must be large enough to fill
the measurement chamber of the sensor
in one go.
WARNING
Avoid pressing on the puncture site too
heavily as sweat and/or tissue fluid can merge
with the droplet of blood and falsify the test
result.
The droplet of blood must not run. Bring the
fingertip with the droplet of blood close to
thetip of the sensor that has been inserted in
the measuring device. The sensor now draws
blood into the measuring chamber 4.
4

12
ATTENTION
The sensor must draw the blood in one go.
The puncture site must therefore be kept
steady when taking the sample. Failure to do
so results in the risk of insucient filling of
the sensor.
If performing lactate tests on third parties,
move the measuring device with its inserted
sensor to the droplet of blood on the
fingertip or earlobe of the subject. Once
themeasurement chamber on the sensor tip is
completely filled, an acoustic signal will sound
and the test will begin. A circular symbol with
a progress bar will be displayed 5. After ten
seconds, a second acoustic signal will sound
and the test result will be displayed in the
measurement unit “mmol/L”. The allocated
memory space number will be displayed
next to the memory symbol. The test result is
stored along with the date and time of the test
and the memory space number 6. Information
regarding interpretation of the lactate value
can be found at:
www.lactatescout.com

WARNING
Lancets and sensors may only be used once.
Used lancets and sensors carry a risk
of infection. Ensure any used lancets
and sensors are disposed of safely
in the domestic waste along with
contaminated cellulose/paper wipes.

2.4 Checking the ambient temperature
To ensure that equally reliable test results are
achieved under dierent climatic conditions,
the measuring device is equipped with a
temperature sensor. The temperature sensor
is located underneath the opening for the
sensors 9.
2.3 Checking the code setting
The code is displayed briefly when you
switch measuring mode on 7. If more than
25 tests are performed with the same code, a
reminder to check the code will be displayed
for three seconds 8. Pressing the OK button
within three seconds will take you to the code
configuration menu.
WARNING
Make sure you do not touch or cover the
temperature sensor with your hand. Failure to
do so results in the risk that the temperature
sensor will read the ambient temperature
incorrectly and the measuring device may
record incorrect test results.
