• 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.
The check performed at room temperature is used as a general functional check. The operating range
specified in the technical specifications is valid without restriction.
1
Hold the monitor so that the display is facing you.
2
Insert a test strip into the slot on the monitor with the contacts first. Ensure the front of the test
strip is facing you (see “Test strip”, page 12).
3
The device automatically switches on and briefly shows the initial display. The device is ready
for measurement as soon as the hand and the symbol flash.
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.
Note
Press the rocker switch “+” or “–”, to change to the control mode. “
” is shown on the dis-
play. This means that the result value is not stored in the memory, therefore not influencing
your measured value statistics. Pressing “+” or “–” again causes “
” to disappear from the
display and the value is stored normally in the memory.
4
A clean surface is required to correctly perform a functional test.
Shake the control solution well before use.
Undo the cap and squeeze two drops next to each other on the
clean surface without touching them. Use the second drop for the
measurement.
Note
Do not apply the drop directly to the test strip to avoid contaminating the remaining control
solution in the bottle by touching the test strip with the tip of the bottle.
5
Hold the input gap (at the tip of the test strip) to the drop of control solution until the gap is
completely filled and the display of the monitor starts counting backwards. When the gap is
sufficiently filled with solution, the device performs a measurement. The device counts down
for approx. five seconds. The measurement is then shown on the display.
