(The error code and Err will alternate on the display.)
A meter or test strip error has occurred.
Repeat the blood glucose test. If a second E-3 code appears,
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
the Understanding Out-of-Range Control Results section in
the chapter Control Tests.
This error could appear if the cap of the test strip container
was not closed tightly. The test strips may have been
damaged due to improper storage or handling.
In rare cases, an E-3 error code may indicate that your blood
glucose is extremely high and above the system's measuring
range. If you do not feel like your blood glucose is extremely
high, repeat the blood glucose test. See the Unusual Blood
Glucose Results section in the chapter Blood Glucose Tests.
If the E-3 code still appears for your blood glucose test,
contact your healthcare professional immediately.
