Beurer GL50 mg/dL 25
5.7 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 monitor 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 blood glucose monitor and/or the test strips
could be faulty or if you have repeatedly measured unusual blood glucose values. Also test the blood
glucose monitor if it has been dropped or is damaged. The control solution is available separately.
Please observe the additional notes in the instructions for using the control solution for the test.
Important
• Do not use third-party control solution. Correct functioning of your monitor can only be tested using
Beurer LEVEL3 + LEVEL4 control solutions.
• 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 monitor, test strip and control solution must be the same temperature.
For the “Functional test using control solution”, the temperature is to be between 20 °C and 26 °C.
1 Insert test strip
Hold the blood glucose monitor so that the display is facing you. 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 3.4 “Test strips” on page 13 ).
2 Wait until the device is ready for use
The device automatically switches on and briefly shows the initial display. The device is ready for
use as soon as the test strip symbol and the flashing blood droplet symbol are displayed.
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.
3 Activate control mode
Press the rocker switch (“+” or “–”) to change to control mode. “
” is shown on the display.
In control mode, the measured value is not saved, meaning your statistics will not be affected.
However, if you do want to save the control measurement in the memory, press the rocker
switch (“+” or “–”) again. “ ” disappears from the display.
