The best way to know what the error code means for your specific meter is to check your meter User’s Manual or with the manufacturer. Error codes and symbols usually indicate that there is a problem with the meter, the strip or user error. Error codes for different meters may mean different things. Once you know what the error code means, there are usually troubleshooting tips available. We often suggest that when any error message occurs, start by removing the test strip and retest using a new strip or follow the instructions in your manual. If you continue to have problems, contact the meter manufacturer’s customer service department by calling the toll-free phone number usually found on the back of the meter.
