Meco Instruments has introduced a vehicle battery system meter for the testing of 12-volt and 24-volt lead acid storage battery within the process of starting the vehicle, charging the battery and loading the electricals. The design of the meter is such that it is operated with the help of four buttons. The result is available on a large LCD screen. Providing a hint of the battery condition by sound and light when being operated, the buttons on the meter enable mode change and test functions. Key features of the meter include battery diagnosis, battery condition display, loose lead detection and reverse polarity protection.
