Beurer GL40 mg/dL 21
5.4 Functional 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 functioning cor-
rectly 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 de-
vice if it has been dropped or damaged. The control solution is available 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
Warning
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 strip” on page 12).
3 The device automatically switches on and briefly shows the start display. The device is ready
for measurement as soon as the hand and the symbol flash.
Note
Press the rocker switch or 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 again. “ ” disappears from the display and the
value is stored normally 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.
