"Error 9" in an ACCU-CHEK Aviva glucometer indicates that the batteries are almost dead, according to ACCU-CHEK. The owner's manual for the device contains directions for replacing batteries, and the company website has a video showing the process. The battery should last for 2,000 tests, Liberty Medical states.
The ACCU-CHEK Aviva glucometer is able to inform the user of a variety of issues. For instance, "Error 1" indicates a damaged test strip or an incorrect key code, ACCU-CHEK explains. "E3" is an alert that the user's blood glucose is very high or there is an error with the test strip or the meter itself. An "Error 8" reports that the environmental temperature is too high or too low to take a proper reading.
ACCU-CHEK's Aviva Blood Glucose Meter obtains blood glucose readings from the tester's fingertip, palm, forearm, upper thigh or calf in about five seconds, reports Liberty Medical. Aviva uses a drum of six preloaded lancets, so users do not handle individual lancets. The sideways motion of a lancet is reduced to decrease user's pain.
The meter determines averages after seven, 14 and 30 days, Liberty Medical states. There is room for 500 hundred readings to be stored. Results are downloadable to a computer.
