Dioguardo Engineering introduces “the fastest voltmeter in car audio.” The all new volt meter isn’t a standard over the counter voltmeter, rather a work of art. The UsainVOLT reads system voltages ranging from 9v up to 24v on a crisp 1.3″ OLED screen coming in either blue or white in color. Using a simple 3 wire hookup (power, remote, ground) and Fairchild Semiconductor® Precision Regulators, so no calibration is needed, this makes it one of the simplest pieces of advanced volt meters out there!
