When "E-9" appears on the screen of an ACCU-CHEK Aviva glucometer, it's time to replace the machine's battery. The error code warns that the battery is almost out of power. If the code shows up even though there is a new battery in the device, the user might need to reset the meter.


How to Reset the ACCU-CHEK Aviva Glucometer

To reset the meter, the user needs to remove the battery from the device. With the battery out, the user can press any button on the meter to complete the reset. After putting the battery in, the device should power up if there are no other errors to correct.


Additional Battery Codes


The E-9 isn't the only error code that warns of a problem with the battery. If the battery icon shows up at the top of the screen, the battery is failing. An Err in the center of the display means the battery is almost out of power. In both cases, it's time to change the battery. Ignoring the warnings can lead to power failure.


What Type of Battery Does the ACCU-CHEK Aviva Glucometer Use?


According to the manufacturer, the ACCU-CHEK Aviva requires two 3-volt lithium coin cell batteries. Shoppers can find this type of battery in many types of stores, including drug stores, general merchandisers and online retailers. The package label should have the product number CR2032.


How Do You Change the Batteries in an ACCU-CHEK Aviva Glucometer?


Changing the batteries is a simple process. Find the battery door on the back of the meter and take off the cover. Take out the old batteries and replace them with new ones. The new ones should have the positive side facing up. Put the battery cover on.


Other Error Codes


The ACCU-CHEK Aviva also has other error codes to let the user know when there is a problem with the device. "E-8" on the display means that the machine is too hot or cold. "E-10" appears when the time and date settings are incorrect. "E-1" indicates a damaged or incorrectly coded test strip. The manual contains a full list of error codes.


Some error codes appear along the top and bottom of the screen. These codes include images or phrases related to the code. The icons include a drop of blood, a test strip, an asterisk and a thermometer.


Tips for Getting Accurate Readings


It's important for diabetics to have accurate measurements of their blood sugar levels. They need to use the information to adjust their medication and diet. There are several steps they can take to ensure accurate results. The first is washing and drying their hands before collecting the blood sample. Another option is to use the second drop of blood instead of the first. The first drop is more likely to contain contaminants.


Diabetics also need to follow the manufacturer's instructions for using and maintaining the meter. The meter should be stored in a dry environment with a stable temperature. A carrying case designed to hold the meter and testing supplies keeps everything together in a single spot.
