Your product may display an error message for a number of reasons, for example if the battery is low. If you’re experiencing an error message, the below images and descriptions should help you to identify the reason why it’s showing.

Blank screen

Dead battery – you need to insert a new one.
Damaged display – please contact Accu-Chek Customer Care.
Defective meter – please contact Accu-Chek Customer Care.
Extreme temperatures – you need to move the meter to a more temperate area.

Three dashes

If you see 3 dashes or hyphens on your display, it means the meter is not coded or the code key is not inserted. Turn off the meter and make sure the code key is properly inserted. If this does not fix the problem, please contact Accu-Chek Customer Care.

Question 4

What does the error E-3 mean?

Accepted Answer

"E-3" in the display means your blood glucose may be extremely high or a meter or a test strip error has occurred. The following instructions should help you understand what action to take:

If your test result matches how you feel, contact your healthcare professional immediately.
If your test result does not match how you feel, repeat the test and refer to Chapter 4, "Unusual Blood Glucose Results" in your owner's booklet.
If the E-3 code still appears for your blood glucose test, your blood glucose result may be extremely high and above the system's reading range. Contact your healthcare professional immediately.
If the second test result does not match how you feel, perform a control test with the control solution and a new test strip.
If the control result is within the acceptable range, review the proper testing procedure and repeat the blood glucose test with a new test strip.

If the control result is not within the acceptable range, see Chapter 2, "Understanding Out-of-Range Control Results."
