Beurer GL40 mg/dL 25
5.4 Function check with control solution
The control solution is used for checking the whole Blood Glucose Monitoring system.
This enables you to determine whether the measuring device and the test strips are func-
tioning correctly together and whether the test is performed correctly.
You should perform a control solution test if you suspect that the measuring device or test
strips may be faulty, or if you repeatedly receive unexpected blood glucose results. Also
test the measuring device if it has been dropped or damaged. The control solution is avai-
lable separately. When performing the control solution test, please follow the additional
instructions in the control solution user guide.
Important
Never use a control solution from other manufacturers. You can only verify the proper
function of your measuring device using the Beurer GL40 control solution.
Performing a function test with control solution
1 Hold the measuring device so that the display is facing you.
2
Insert a test strip into the slit on the measuring device, contacts first. Ensure that the
front side of the test strip is facing towards you (see "Test strip", page 14).
3
The unit switches on automatically and briefly shows the start display. As soon as the
hand
and the symbol are flashing, the unit is ready to perform measurements.
Note
Press the S or T rocker button to switch to control mode. "CtL" appears in the dis-
play. This means that the result is not saved in the memory so that your measure-
ment statistics are not falsified. Pressing S or T again causes "CtL" to disappear
from the display again and the value is stored as usual in the memory.
4
Shake the control solution well before use. Unscrew the cap and squeeze out a drop
of solution. Wipe away the first drop and squeeze out an additional drop.
5
To prevent the remaining control solution in the bottle from becoming contaminated
through the tip of the bottle in contact with the test strip, do not apply the drop directly
to the test strip. Apply the drop to a clean substrate. Then put the drop on the slit for
receiving blood on the test strip. The solution is sucked into the slit. Wipe the tip of the
bottle using a clean, dry paper tissue.
6
Once the slit is filled with solution, the unit begins the measurement. The unit counts
down for approx. five seconds. Then the measurement result is shown in the display.
7
Check whether the result is within the specified results range for the control solution.
This results range is printed on the container with the test strips.
