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 section Performing a Control Test 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.
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.
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.
An electronic error occurred, or in rare cases, a used test strip was removed and reinserted. Turn the meter off and on, or take the battery out for 20 seconds and reinsert it. Perform a blood glucose or control test.
The temperature is above or below the proper range for the system. Refer to the test strip package insert for system operating conditions. Move to an area with the appropriate conditions, wait 5 minutes, and repeat the blood glucose or control test. Do not artificially heat or cool the meter.
The battery may be out of power.
Turn the meter back on. If you are in a cold environment, move to a location with a more moderate temperature and retest. If the message continues to appear after several attempts, replace the battery. If the message reappears after the battery has been replaced, remove the battery, press and hold the Power/Set button for at least 2 seconds, then reinsert the battery with the (+) side facing up.
The time and date settings may be incorrect. Make sure the time and date are correct and adjust, if necessary.
