Display
Blood glucose
Action
High blood glucose level
on an empty stomach,
above 100
mg/dL
(5.6
mmol/L)
2 hours after a meal
over 140
mg/dL
(7.8
mmol/L)
If this high value persists 2 hours
after your last meal, this may in-
dicate hyperglycaemia (high blood
glucose). Seek medical attention
to coordinate any measures, if ap-
plicable.
High blood glucose level,
possibly ketones
over 240
mg/dL
(13.3
mmol/L)
Perform a ketone test. For this pur-
pose, seek medical attention.
Very high blood glucose
level
over 630
mg/dL
(35.0
mmol/L)
Take another measurement using a
new test strip. If the display is the
same as before: seek medical as-
sistance immediately.
5.6 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 monitor and/or the test strips could be faulty
or if you have repeatedly measured unusual blood glucose values. Also test the monitor if it has been
dropped or is damaged. The control solution is available separately. For the control solution test,
please observe the additional notes in the instructions for use for the control solution.
Important
• Do not use control solutions by a di
ff
erent manufacturer. Correct functioning of your monitor can
only be tested using Beurer control solutions ( LEVEL4).
• 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 mon-
itor.
Performing a functional test using control solution
Warning
To obtain correct results, the monitor, the test strip and the control solution must be the same tem-
perature. For the “Functional test using the control solution”, the temperature is to be between 20°C
and 26°C.
