Meco Instruments Pvt. Ltd. has introduced a vehicle battery system meter. It is capable of testing a 12 volt and 24 volt lead acid storage battery. Called VBSM6246, the battery system tester works even when the vehicle is running; when the battery is being charged or at the time of loading. The battery system tester has four buttons, ‘Enter’, ‘Esc’, ‘up’ and ‘down’, to facilitate its operation. The buttons can be used to change the mode, or for testing the function. The ‘Enter’ button, for example, is used for both, to select mode and test function. The ESC button is used as a return key. The results of the meter are fed to a large LCD screen and notified to the end user by the way of sound and light signals. Key parameters of the battery being tested are displayed as part of battery diagnosis. The meter thus displays battery condition, protection against overload, detection of loose lead and reverse polarity.
