carrying out a self-test
Every time you feed a test trip into the measuring device (
Fig. 1
), the display will
show "CHK" for check and the "Test strip" symbol. These show that the system is
briefly carrying out various self-tests. Once the self-test is finished, you will hear a
long beep followed by a short one. When the test trip is removed, you will hear a
shorter beep.
why coding?
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.
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.
