1.2 The main features at a glance
Fast testing
The meter needs only approximately 5 seconds for
each test.
Flagging
results
You can flag results with different symbols, which
indicate particular situations during the test.
Easy
testing
For testing, you do not need to press a single
button. You insert a test strip into the meter, which
switches it on, apply blood to the test strip, read
the value and then pull the test strip out of the
meter.
Memory
The meter automatically saves up to 350 results
with the time and date of the test and all other
information that is important for the test.
Blood
volume checking
To perform a test, the meter requires 1–2 µL blood
(1 µL (microlitre) = 1 thousandth of a millilitre). The
meter detects if the applied amount is not sufficient.
14
Integrated data analysis
From the stored test results your meter can calculate your average values for the last 7, 14 or 30
days.
Getting to know your meter
Data
transfer
The meter has an infrared port enabling you to
download stored test results to a computer.
Applying
blood outside the meter
When the meter prompts you to apply blood, you
can remove the test strip from the meter, apply the
blood and insert it back into the meter.

support and service centre (see Chapter 17).
16
Steps before testing
2.2 Checking the unit of measurement for blood glucose
Blood glucose results can be displayed in two different units (mg/dL or mmol/L). Two different versions of
the same meter are therefore available. Please check
if your meter displays the unit you are accustomed to.
You can find the unit of measurement that your meter
displays on the type plate on the back of your meter.
If you do not know which is the right unit for you, ask
your doctor.
The unit of measurement that your meter
displays cannot be changed. If the wrong unit
is printed on the type plate, please consult
your dealer or pharmacy. A wrong unit of
measurement could lead to test results being
misinterpreted.

Setting the time and date
The time and date is not preset in new meters. You
can still, perform blood glucose tests. In this case,
however, the meter displays the time 0:00 (0:00am)
and the date 0- 0. This means that test results are
saved without a time and date. Averages cannot be
calculated, and when downloaded to a computer, the
statistical evaluation of test results is very restricted
or cannot be performed at all.
When you set the time and date for the first time, the
factory defaults are displayed.
So that test results are saved with a time and date,
you must set the time and date and, if required,
change the format in which they are displayed.
3.Year (year of manufacture)
The settings are made in the following order (default
in brackets):
1.Time and date format (24-hour display with daymonth date format)

Coding
4
Coding
A code chip is used to give the meter information
about the properties of the test strips. This is why
each pack of test strips contains a code chip.
28
Each time you open a new pack of test strips,
you must replace the old code chip from the
meter with the new one from the pack. Code
chips from other packs may contain information that is incorrect for your new test strips,
and can therefore lead to incorrect test results.
Incorrect results can cause the wrong therapy
recommendation to be made and so lead to
serious adverse health effects.
Coding
1 Compare the code number on the chip with the
corresponding code number on the label of the
test strip container.
The three-digit number on the code chip (e.g. 689)
must match the three-digit number on the label.
Leave the meter turned off.
2 Gently slide the code chip into the slot on the
side of the meter.
You must feel the code chip lock into place.

Testing blood glucose
Please also consult the directions given at the end of
this Chapter in the section “Notes on blood glucose
testing”.
5.1 Preparing to test blood glucose
You need the following items to carry out the test:
your meter with the code chip inserted
the pack of Accu‑Chek Active test strips that
belong to the code chip
a lancing device to collect blood
a lancet for the lancing device
30
1 Read the package insert which came with the
test strips.
2 Wash your hands with warm water and soap,
and dry them well before you start to perform
the test.
This helps remove any residues from the skin (e.g.
from food, drinks or skin cream) which can disturb
the test. This also stimulates blood flow and reduces
contamination of the puncture site.
3 Prepare your lancing device to collect blood.

You can flag test results to describe certain events
connected to the result or particular characteristics of
the result. You can only flag a test result while the
test strip is still in the meter and the result is being
displayed.
The General flag (asterisk symbol ): You can
define the meaning of this flag yourself. For example, you can, use it for test results that you have
obtained from alternative sites or after physical
activities.
You can choose from 4 flags:
The Control flag (bottle symbol ) is intended for
performance checks in which you apply control
solution to the test field instead of blood (see
Chapter 7).
The Before Meals flag (apple symbol ) is intended for test results that you have measured before
your meals.
The After Meals flag (apple core symbol ) is
intended for test results that you have measured
after your meals.

5.3 Checking the test result using the test strip control window
The test strip itself allows you to estimate the test
result and thus also to check the displayed result.
Before the test
There is a round coloured control window on the
back of the test strip.
1 Compare the colour of this window with the
coloured dots on the label of the test strip
container.
The colour of the control window must match the
colour of the top coloured dot (0 mg/dL, 0 mmol/L).
If the control window is a different colour, you must
no longer use the test strip.
43
Testing blood glucose
After the test
The label on the test strip container shows blood
glucose values in mg/dL und mmol/L next to each
colour sample.
1 Look for the value which is closest to your test
result.
Within 30–60 seconds after applying blood:
2 Compare the colour of the control window on the
back of the test strip with the coloured dots on
the label of the test strip container.
44
If you find there is a noticeable disparity, repeat the
test. If you cannot obtain a match, even after several
tests, contact your customer support and service
centre.
Only the test results displayed by the meter should be
used for therapeutic decisions. The colour comparison serves only as a plausibility check of the test
results.

5.5 Notes on blood glucose testing
Incorrect results can cause the wrong therapy
recommendation to be made and so lead to
serious adverse health effects.
Therefore, please follow the following instructions:
Only use the Accu‑Chek Active meter with
Accu‑Chek Active test strips that are approved by
Roche Diagnostics GmbH. Other test strips deliver
incorrect results.
If the code number on the display does not match
the code number on the test strip container, do not
perform blood glucose tests. Incorrect coding
produces incorrect results.
46
Use only test strips with an expiry date which has
not been exceeded. Test strips with an expiry date
that has already passed can produce incorrect
results. If the expiry date has passed, the
symbol will be displayed in the test strip symbol.
Check the expiry date on the label of the test strip
symbol.
container. You will find it next to the
Also check that the current date is set in the meter
and that the inserted code chip belongs to the test
strip you are using.
Testing blood glucose
The test strips are sensitive to humidity and
moisture. Only remove test strips from the container when your hands are completely dry. Close
the test strip container again tightly with its original cap immediately after removing a test strip.
The cap of the test strip container contains a
drying agent which protects the strips from moisture. If moisture gets into to the test strip container
through handling test strips with moist hands or if
the container is left open, the drying agent loses its
effect. Unusable test strips may lead to incorrect
results.
If you have not applied blood to the test strip in the
available time and the meter has turned off:
Remove the test strip and dispose of it. Start the
blood glucose test again with a new test strip.
If you have removed the test strip from the meter

not use this test strip any more even if you have
not yet applied any blood. Start the blood glucose
test again with a new test strip.
47
Testing blood glucose
You can touch the test field when you apply blood,
but do not rub the drop of blood into the test field.
Please also note the following points, as incorrect
results or error messages can otherwise occur:
Do not store used test strips in a container which
still contains unused test strips. This could make
the unused test strips unusable. Unusable test
strips can lead to incorrect results.
Do not bend the test strip while inserting it into the
meter.
Do not to bend or move the test strip before or
while applying blood, or while the test is performed.

Further information
If you missed the code number in the display after
you inserted the test strip, remove it from the
meter and re-insert it.
If you want to apply blood to a test strip which is
not inserted into the meter: Do not remove the test
strip until the drop symbol flashes in the display. If
you remove the test strip before this time, the
meter turns itself off.
If the displayed test result reflects the way you
feel, continue as instructed by your doctor. If
the displayed test result does not reflect the
way you feel, please perform a performance
check with an Accu‑Chek Active control
solution (see Chapter 7). Repeat the blood
glucose test afterwards. If the latest test result
still does not reflect the way you feel, please
contact your doctor.
Do not change your treatment based on just
one result.
49
Testing blood glucose
Measuring range
The meter measures blood glucose results in the
range from 10 to 600 mg/dL (0.6–33.3 mmol/L).
If the result is lower than 10 mg/dL (0.6 mmol/L),
is displayed instead of a result.

6.1 Memory
Your meter can save up to 350 test results with their
time and date. You do not need to do anything to save
the results. The meter automatically saves all test
results.
In addition to the results, the time and the date, your
meter also saves other information that is important
for the test. This includes all symbols which are
displayed with the result (except the battery symbol)
and the flags with which you marked the results.
If all the memory locations are occupied, the oldest
test result is deleted to create space for the new one
when you perform a new test.

The meter calculates the average for a period even
when the saved results cover a shorter period. For
example: Tests were only performed in the last 5
days. In this case, the results of the last 5 days are
used to calculate the averages for all three periods
(7, 14 and 30 days).
In the event that you changed the date or time,
performed a test and then re-set the date/time, only
those test results that the meter saved in uninterrupted chronological order will be taken into account.
If the chronological order has been interrupted, the
earlier results will not be taken into account.
You can switch directly from displaying any average

7.3 Possible sources of error during performance checks
If the result is outside the specified concentration
range, repeat the performance check. If the result of
the second check is also outside the concentration
range, please check the following points.
If your responses to the questions below are different
from those given, make the respective corrections
when you perform the next test. If you have taken all
of these points into account and the results are still
outside the specified concentration range, contact
your customer support and service centre.
If a performance check produces results that
are outside the specified concentration range,
it is no longer certain that the meter and test
strips are functioning properly. Blood glucose
tests may then produce incorrect results.
Incorrect results can cause the wrong therapy
recommendation to be made and so lead to
serious adverse health effects.

Testing blood glucose in more than one patient – Information for healthcare professionals
10 Testing blood glucose in more than one patient – Information for health‑
care professionals
Only staff working in doctors’ practices, hospitals and
diabetes training centres, and nurses are allowed to
perform blood glucose tests on more than one patient
using the same Accu‑Chek Active meter.
When using the meter always follow the recognised
procedures for handling objects that are potentially
contaminated with human material. Practise the
health and safety policy of your laboratory or institution.
Please also follow the instructions on the following
pages to prevent the meter becoming contaminated.
Any patient with an infection or suffering
from an infectious disease and any patient
who is a carrier of a multi-resistant micro‑
organism must be assigned his/her own
meter. This also applies if it is suspected
that a patient has one of the above. During
this time the meter must not be used to
test any other patient.
91
Testing blood glucose in more than one patient – Information for healthcare professionals
Patients and medical staff are potentially at
risk of becoming infected if the same
Accu‑Chek Active meter is used to test blood
glucose in several patients. All objects that
come into contact with human blood are
potential sources of infection (see: Clinical and
Laboratory Standards Institute: Protection of
Laboratory Workers from Occupationally
Acquired Infections; Approved Guideline –
Third Edition; CLSI document M29-A3, 2005).
92
Residues of water or disinfectant on the skin
can dilute the drop of blood and so produce
incorrect results.
Dispose of used lancets or disposable lancing
devices and used test strips according to the
health and safety policy of your laboratory or
institution.
Testing blood glucose in more than one patient – Information for healthcare professionals
10.1 Testing blood glucose
1 Wear protective gloves.
2 The patient’s hands should be washed with
warm water and soap and then dried well. If you
are using alcohol wipes, the finger must also be
completely dry. On dry skin the drop of blood
cannot spread so easily.
3 Use only lancing devices approved for use by
healthcare professionals.
4 Use a lancing device with adjustable penetration
depth settings.
5 Select a penetration depth to suit the nature of
the patient’s skin. Start with a shallow depth
setting.
6 Select a puncture site along the side of a fingertip.
7 Turn the finger so that the chosen puncture site
is facing upwards, and keep it facing upwards.
Then the drop of blood cannot spread so easily
later.
8 Prick the side of the fingertip.

meter.
95
Measurement and storage conditions
11 Measurement and storage conditions
So that the meter works reliably and you obtain accurate results, make sure that the conditions listed on
the following pages are met.
11.1 Temperature
For blood glucose tests and performance checks
the temperature must be between +10 and
+40 °C.
If the temperature is at the limits of the permitted
range (between +5 and +10 °C or between +40
and +45 °C), you can still perform a test. The
96
thermometer symbol will, however, be displayed
(see also Chapter 12.1).
Do not use results obtained at the limits of
the permitted temperature range as a basis
for making therapeutic decisions, as they
could be incorrect. Incorrect results can
cause the wrong therapy recommendation
to be made and so lead to serious adverse
health effects.
Measurement and storage conditions
Tests cannot be performed at temperatures below
+5 °C and above +45 °C. In this case the following
appears in the display:
tion to be made and so lead to serious
adverse health effects.
Keep the meter without battery at a temperature
between -25 and +70 °C.
Keep the meter with battery at a temperature
between -10 and +50 °C.
At temperatures above +50 °C the battery
could leak and damage the meter.
Never try to speed up warming or cooling of
the meter, e.g. in a refrigerator or on a
radiator. The meter can be damaged and
provide incorrect results. Incorrect results
can cause the wrong therapy recommenda-
At temperatures below -10 °C the battery
does not have enough power to keep the
internal clock functioning.
97
Measurement and storage conditions
11.2 Atmospheric humidity
11.3 Light conditions
Only test blood glucose when atmospheric humidity
is below 85 %.
Do not perform a test when the meter and the test
strips are exposed to direct sunlight. Go to a shaded
place or shade the meter, for example with your body.
Keep the meter below 93 % atmospheric humidity.
Sudden changes in temperature cause
condensation to form in or on the meter. If this
has occurred, do not turn the meter on. Allow
the meter to slowly cool down or warm up.
Never keep it in a moisture-prone area (e.g. a
bathroom).
98
If the meter is exposed to too much light, tests
cannot be performed. In this case the following
appears in the display:
Measurement and storage conditions
11.4 Sources of interference
Avoid sudden changes in light conditions while
testing. The flashlight of a camera, for example, can lead to incorrect results.
Keep the meter away from very strong light
sources (e.g. direct sunlight, studio lighting,
etc.). These may stop the meter from functioning correctly and lead to error messages.
Strong electromagnetic fields may interfere
with the proper operation of the meter. Do not
use the meter in close proximity to a strong
electromagnetic field.
To avoid electrostatic discharge, do not use
the meter in a very dry environment, especially
one in which synthetic materials are present.

Technical data
Performance analysis
The performance data for the Accu‑Chek Active system (Accu‑Chek Active
meter with Accu‑Chek Active test strips) was obtained using capillary blood
from diabetic patients (method comparison, accuracy), venous blood (repeatability) and control solution (reproducibility). The system is calibrated with
venous blood containing various glucose concentrations. The reference values
for this were obtained using the hexokinase method. For method comparison,
the results were compared with results obtained using the hexokinase method
with deproteination (automatic analyser). The hexokinase method is traceable to
a NIST standard.
The Accu‑Chek Active system meets the ISO 15197 requirements.
