When to Perform a Control Solution Test:
1. Insert the test strip to turn on the meter. Wait for the meter to beep
and display the test strip and blinking blood drop symbols.
2. Press C to mark this test as a control solution test. With “CTL”
displayed, the meter will not store your test result in memory. If you
press the C button again, the“CTL” will disappear and this test is no
longer a control solution test.
WARNING: When doing a control solution test, you need to press the
C button to mark it so the test result will not be stored in the memory.
Failure to do so will mix up a control solution test result with a blood
glucose test result in the meter memory.
3. Apply control solution.
Shake the control solution vial thoroughly before use.
Squeeze out a drop and wipe it o, then squeeze out
another drop and place it on the tip of the vial cap.
Hold the meter and test strip at a 45˚ angle as you touch
the drop. Once the absorbent hole lls completely, the meter will begin
counting down from 7 seconds. WARNING: To avoid contaminating the
control solution, do not directly apply control solution onto the strip.
4. Read and compare the result. After counting down to 0, the control
solution test result will appear on the display. Compare this result with
the range printed on the test strip vial. It should fall within this range. If
not, please read the instructions again
and repeat the control solution test.
