LAUNCH X431 EURO TAB User Manual59Fig. 11-9Tap [OK], test data will be shown on the screen.Note: It is unnecessary to perform charging system and start system test after finishingbattery test, but battery test must be done before undergoing charging system andstarting system test.11.4.3 Outside the vehicle testIt only applies to battery test and detecting floating electricity will be ignoredwhile performing battery test.On Fig. 11-4, tap [Outside the vehicle] to select battery test standard.The following operation steps are identical to Steps 6~7 in Chapter 11.4.2Battery test. Please refer to it for details.11.5 Precautions on Battery TestFor the purpose of getting accurate test results, unless otherwise specialrequired, all loads need to be power off such as headlamp, engine etc. beforetesting battery.The operating time required for charging system and actuation system testvaries from person to person. If the engine does not start or accelerate within 30seconds, the system will prompt you “receiving timeout” and return to the initialstatus.Whether Engine is off or not has no influence on charging and actuation testresult after increased speed is detected, but other loads need to be powered off.The accuracy of battery voltage, charging voltage, start voltage is 0.01V in testresults; CCA (Cold Cranking Amps) precision is 5CCA.Generally, charging voltage value is greater than starting voltage.Charging voltage range is as follows: 13.8--14.5V for domestic vehicle;13.3--15.5V for imported vehicles. The voltage varies with different car models,so you have to judge based on related vehicle models. In general, the DCvoltage is stable, but it also varies with different revolution speed.Starting voltage range: The value higher than 9.6V is regular, otherwise it is toolow. Due to different situations, whether the starting voltage is higher or not doesnot mean the vehicles or batteries are faulty.
