Troubleshooting Checks

1. Check the expiration dates of the test strips

and control solutions.

2. Make sure the caps were tight on the test

strip vial and control solution bottles.

3. Check if the code on the meter matches the

code on the test strip vial.

4. Make sure you followed all the testing steps.

5. Make sure the temperature was between

57 to 104ºF (14 to 40ºC) when you did the test.

6. If none of the above apply. . .

Action

Replace solution or strips that have expired or

solution you opened more than three months ago.

If either has been open for a while, replace the

test strips or control solution.

If not, recode the meter (see page 13).

Reread pages 16-18 and test again or ask your

healthcare provider for help.

Repeat the test within the appropriate temperature

range.

Repeat the control test with a new test strip.

If the result still isn’t within the acceptable

range, contact Accu-Chek Customer Care at
