 Do not connect battery tester to jump start or charging terminal point when the battery is installed; always connect it directly to the battery.
Otherwise the test result may be incorrect.

 All test steps and entries must be conducted painstakingly.
Otherwise the test result may be incorrect.

 Whenever possible, perform the tests with the battery still installed and connected.

1	Switch off ignition.

2	Switch off interior and exterior lights.

3	Switch off audio component (e.g. radio).

4	Connect battery tester to battery.

 Check battery tester is securely connected to battery.
Otherwise the test result may be incorrect.

 Once the battery tester has been connected the currently measured battery voltage is displayed.
During the test procedure, the battery tester may detect so-called "system noise".
In this instance, check whether all consumers are switched off and wait approx. 2 minutes until the quiescent current is minimized and the bus systems are shut down.

5.1	If battery installed, when the "Surface voltage" message is shown during the test. Reduce increased voltage as per the battery tester specifications (e.g. switch on driving lights).

5.2	If battery removed, when the "Surface voltage" message is shown during the test. Reduce increased voltage using a suitable load tester (load battery for approx. 60 s with 20 A to 30 A).

6	Conduct test procedure to match the battery tester menu navigation.

7	After the test print out the test code displayed and store it safely in a tamperproof manner.
