18 

Beurer GL42 mg/dL

 Important 

• Do not use third-party control solution. Correct functioning of the measuring device can only be 

tested using the Beurer control solutions ( LEVEL6).

•  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 moni-

tor.

Performing a functional test using control solution

 Warning 

To obtain correct results, the measuring device, the test strip and the control solution must be the 

same temperature. For the “Functional test using the control solution”, the temperature is to be be-

tween 20 °C and 26 °C.

1

Hold the blood glucose monitor so that the display is facing you.

2

Insert a test strip into the slot on the blood glucose monitor with the contacts first. Make sure 

that the front of the test strip is facing you (see “Test strips” on page 12).

3

The device automatically switches on and briefly shows the initial display. The device is ready 

for measurement as soon as the hand   and the   symbol flash. 

IMPORTANT:

 Control solutions and blood react to temperature influences in different ways. 

It is therefore of vital importance that control solution measurement is always performed in 

control solution mode. If this mode is not used, results may be obtained that are outside the 

target range.

 Note

Press the rocker switch “+” or “–” [2] to change to the control mode. “

” is shown on the 

display. This means that the result value is not stored in the memory, therefore not influencing 

your measured value statistics. Press “+” or “–” [2] again. “

” disappears from the display 

and the value is stored normally in the memory.

4

A clean surface is required to correctly perform a functional test.

Shake the control solution well before use. 

Undo the cap and press two drops next to each other on the 

clean surface without touching them. Use the second drop for 

the measurement.

 Note

Do not apply the drop directly to the test strip to avoid contaminating the remaining control 

solution in the bottle by touching the test strip with the tip of the bottle.
