Beurer GL42 mg/dL 19
5 Hold the input gap (at the tip of the test strip) to the drops of control solution until the gap is
completely filled and the measuring device in the display starts counting backwards.
When the gap is sufficiently filled with solution, the device performs a measurement. The de-
vice counts down for approx. five seconds. The measured result is then shown on the display.
6 Check whether the result is within the specified range of results for the control solution. This
range of results is printed on the test strip box.
Expected results
At room temperature, the measurements of the test using the control solution should be within the
range printed on the test strip box in approx. 95% of all tests.
Warning
The result range printed on the test strip box applies only to the control solution. This is not a rec-
ommended value for your blood glucose level.
If measured values are outside the specified range, check the following possible causes:
Cause Action
• The first drop of control solution was not dis-
posed of.
• The tip of the bottle was not cleaned correctly.
• The bottle was not shaken well enough.
Rectify the cause and repeat the test.
Control solution and/or test strips have passed
their expiry date or are contaminated.
Repeat the test using a new bottle of control
solution and/or new test strip.
The control solution, test strips or blood glucose
monitor are too warm or too cold.
Bring the control solution, test strips and blood
glucose monitor to room temperature (+20 °C to
+26 °C) and repeat the test.
The test strips and control solution were kept at
a temperature and humidity outside the speci-
fied range.
Repeat the test using new/correctly stored test
strips and control solution.
Damaged test strips.
For example
• Test strips that were exposed to fresh air for
too long.
• The test strip box was not closed completely.
Repeat the test using a new test strip and/or a
new box of correctly stored test strips.
Old test strips. Open a new box of test strips. Repeat the test.
There is a problem with the blood glucose moni-
tor.
