Description: The car digital voltmeter has easy to read and connect to your 12 volt system. Mainly used to monitor the storage-battery voltage and know the running status of the voltmeter and also can be applied to measuring the voltage of other products. Features: brand new and high quality Waterproof, dustproof, shockproof. Simple connection, easy to use. Mini size with 3-digit LED digital display. Measures for DC voltage precisely from 8V to 16.0V. Widely used for cars, motorcycles, bikes, substation automation, distribution automation, test equipment, voltage regulator and so on. Battery status and working status of the generator: When the voltage is lower than 11.5V or higher than 19.8V, the voltage alarm will appear and the voltmeter will flash constantly. Displays "LLL" when the voltage is lower than measuring range; displays "for HHH" when the voltage is higher than the measuring range.
