Features This is a nice little voltmeter designed for a 12V car or motorcycle. When the voltage is lower than the range, it displays "LLL"; when the voltage is higher than the range, it displays "HHH". It can measure and display real-time voltage data between 8V and 16V DC. The large LED display is legible and waterproof. When the voltage is lower than 11.5V or higher than 19.8V, the numbers on the voltmeter display will flash to alarm.
