Possible Sources of Error
If you receive frequent error messages, or if you often obtain questionable results, please check the following:
• Are only ACCU-CHEK Go test strips being used with the meter?
• Does the code number on the display match the number printed on the test strip vial?
• Does the battery still have enough power, and is it properly inserted?
• Have you completely removed the protective film from the battery?
• Have you carefully read the User’s Manual and carried out tests as instructed?
•
Have you read the package inserts that came with the test strips? Have you stored and used the strips correctly?
• Have you followed all the proper measurement and storage conditions?
• Are the test strips and/or control solution still within the stated expiration date?
• Are the test strip guide and measurement optics clean?
• Is the measurement optics cover in place?
If the answer to all these questions is "yes," carry out a control test with a new test strip as described in
Chapter 2. If this check confirms the meter is working properly, please read the instructions in Chapter 3 again
and perform another blood glucose test with a new test strip.
If you have checked all these points and still are having problems, please contact the ACCU-CHEK Customer
Care service center at 1-800-440-3638.
