Practical Built-In AVOmeter

Autel AL539 is a code reader equipped with easy-to-read AVOmeter which allows you to get quick and accurate test result of battery voltage, continuity and current at the fingertips.

Circuit Test: Used for diagnosing the vehicle electrical system, including DC or AC voltage test, continuity test, and current test. Starting Test: Measure the cranking voltage to have a test of vehicle’s starting system which is commonly referred to as the “cranking system” to confirm its functioning properly, or provide valuable diagnostic information for isolating a problem in the system. Charging Systems Test: Ensures the battery will remain charged to; starts the vehicle and powers the accessories while it’s running; tests the integrity of the 12-volt charging system periodically. NOTE: AL539 only works on 12V vehicles, NOT for 24V. Never connect the battery test cable to a voltage source greater than 30V or that may cause potential damage of the unit.
