carrying out a self-test
Every time when you feed a test strip into the measuring device (Fig. 5), or
switch the device on, all display segments in the display are illuminated briefly.
This shows you that the system is carrying out various self-tests and also allows
you to check that all display segments are working properly.

The code numbers are used to calibrate the test strips with the device in order
to achieve exact test results. Before you use a device for the first time, and
every time you use a new container of test strips, you must first feed the
check/code strips into the device. After this, every time you carry out a test you
should check that the number which appears in the display is the same as the
code number on the test strip container (Fig. 6).
Warning: If the code number displayed is not the same as the code
number on the test strip container, the measured results can
be falsified.
