Langer lead-acid battery tester main functions of automotive testing equipment

Langer battery tester, its main functions are: car battery detection, auto starter system testing, vehicle charging system testing, and other additional features. Car battery testing, mainly for automotive battery state of health were analyzed to calculate the actual cold-start ability of the battery to determine the degree of aging cells, to provide a reliable basis for analysis for the automotive battery testing and maintenance. When the battery aging, can be informed in advance owners to replace the battery. Auto starter system testing, mainly for automobile starter motor for testing and analysis, testing actually required starter motor starting current, starting voltage, which can determine whether the starter motor is normal. Starter motor is not normal, it may have the following causes: lubrication system failure, resulting in the start load torque increases; vehicle starter motor rotor sweep chamber, resulting in increased friction and so the starter motor itself. Vehicle charging system testing, mainly for vehicle charging systems for testing and analysis, including generators, rectifiers, rectifier diodes, through testing, can know the generator output voltage is normal, if normal rectifier diode, the charging current is normal. If the generator output voltage or current is not normal or rectifier diode partially damaged, it will cause the battery always in charge dissatisfied overcharge or charged state, causing rapid damage to the battery, but also make the life of the car other electrical load is greatly reduced. Other additional features include: language selection, voltmeter, display backlight brightness adjustment and so on.
