Calibrating The Device / Carrying Out A Self-Test / Why Coding - IBP TD 4222 Mode D'emploi

7 calibrating the device
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.
