5.6 Functional check using control solution
The control solution is used to test the entire blood glucose monitoring system. This helps to deter-
mine whether the measuring device and the test strips are working optimally together and whether
the test is being performed correctly.
Perform the control solution test if you suspect that the monitor and/or the test strips could be faulty
or if you have repeatedly measured unusual blood glucose values. Also test the monitor if it has been
dropped or is damaged. The control solution is available separately. For the control solution test,
please observe the additional notes in the instructions for use for the control solution.
Important
• Do not use control solutions by a different manufacturer. Correct functioning of your measuring de-
vice can only be tested using Beurer control solutions (LEVEL 7 + LEVEL 8).
• Control solution measurements: When using the device, specialist personnel must follow statutory
guidelines.
• Do not apply any blood samples or control solutions to the test strip before inserting it in the monitor.
Performing a functional test using control solution
Warning
To obtain correct results, the monitor, the test strip and the control solution must be the same tem-
perature. For the “Functional test using the control solution”, the temperature is to be between 20 °C
and 26 °C.
The check performed at room temperature is used as a general functional check. The operating range
specified in the technical specifications is valid without restriction.
1
Hold the monitor so that the display is facing you.

Insert a test strip into the slot on the monitor with the contacts first. Ensure the front of the test
strip is facing you (see “Test strip”, page 13).
