Meter Maintenance and Troubleshooting

(The error code and Err
will alternate on the
display.)
A meter or test strip error has
occurred.
This error message could appear if
the cap on the test strip container was
not closed tightly. The test strips may
have been damaged due to improper
storage or handling.
Never make therapy decisions
based on an error message.
Repeat the blood glucose test. If a
second E-3 error message appears,
perform a control test with the control
solution and a new test strip. See the
Performing a Control Test section in
the chapter Control Tests. If you
continue to receive an E-3 error
message, use an alternate method for
testing your blood glucose, such as a
back-up meter and test strip. If the
alternate method gives an extremely
high blood glucose result, or if an
alternate method is not available,
contact your healthcare
professional immediately.
In rare cases, an E-3 error message
may indicate that your blood glucose
is extremely high and above the
system’s measuring range. See the
Unusual Blood Glucose Results
section in the chapter Blood
Glucose Tests for other possible
causes of the error message.
(The error code and Err
will alternate on the
display.)
Not enough blood or control solution
was drawn into the test strip for
measurement or was applied after the
test had started.
Discard the test strip and repeat the
blood glucose or control test.
(The error code and Err
will alternate on the
display.)
Blood or control solution was applied
to the test strip before the flashing
drop symbol appeared on the display.
Discard the test strip and repeat the
blood glucose or control test.
(The error code and Err
will alternate on the
display.)
An electronic error occurred.
Remove the batteries, press and hold
either meter button for at least 2
seconds, and reinsert the batteries.
Perform a blood glucose or control
test.
