Unfortunately there is no easy way. The meter has an internal battery that holds the reading for up to 72 hours. You would have to remove the regular battery and let the meter sit for three days.
Error 9 on the 535 version of the aviva meter will indicate a fresh battery is requird. If you put a new battery into the unit and it displays E-9 again, take the battery out, press any button (arrow or power) and then insert battery again and give it a try. If the same issue is occurring please let accu-chek customer care know so they can replace the unit at no cost.
E-9 means the battery is low. Change the battery. If you still get the message than the battery needs to be replaced and the meter needs to be reset. Take the battery out. Press the left arrow key on the front. Insert a new battery (do not turn the machine on). Press the left arrow button again. Now you should be prompted to set the time and date. Once you have done that, power the meter off and you should be all set. Of course, they don't tell you any of this in the manual. Considering they charge you $105 for 100 test strips you would think they could have an up to date manual on their website... but they don't because they suck.
The accu-chek comfort curve cannot be used with the aviva unit. The advantage meters and comfort curve strips are being discontinued.
First check you battery. Use a volt meter must have more than 12.2 volts, if under 12 volts, charge or change battery. No volt meter, then turn on your headlights, if good, then check shifter, in park and in neutral. If no headlights, charge battery.
Check the battery with a vom meter while the engine is running. It should read about 14.5 volts and if so the alternator is working, than have the battery checked Now if the meter does not read 14.5 volts, have the battery, and the alternator checked. If they both check out okay, the problem is in the battery or the alternator circuit on the vehicle.
I had this problem. The alternator was fine, it was the battery that was bad. The alternator was "pegging" out the indicator bc it was trying to charge the battery, but it wasnt taking charge. Take the battery out and have it checked.
Charge the battery, start the car and check the battery with a volt meter. Should have over 14 volts, if only say 12.4 to 13, then change the alt. or check the wiring.
the battery on your meter has to be replaced.
The meter on your battery charger will be in the green
Just connect a resistor and a small battery in series with the galvanometer,change the markings on the meter's scale, and you have an ohmmeter.
Remove the battery and check it with a volt meter.
