test strip is damaged
Code E-9 on an Accu-Chek glucose meter typically indicates an error related to the test strip or the meter itself. This error code may appear when the test strip is not inserted correctly, is damaged, or has expired. It could also indicate a problem with the meter's functioning or calibration. It is important to troubleshoot the issue by ensuring proper insertion of a new, undamaged test strip and following the manufacturer's instructions for calibration and maintenance.
E-5 indicates that the optical lens (reading lens is dirty). The lens is located where the strip ejects not exactly where the drum is located. The area will have a box with black and white dots and the lens is right underneath it. The manual does state alcohol can be used but it is better to apply a little water to a q-tip to clean and dry the lens. Sometimes E-5 can also indicate that a strip is stuck in the unit.
