DLP Design DLP-PMV Hands-Free Protometer® Voltmeter is a hands-free energy meter designed to reduce clutter in workbench areas. The device is ideal for use on solderless breadboards. The device's LCD display presents positive and negative voltage readings without having to reverse the connection to the circuit. DC measurements are calculated by an average value. AC measurements are determined by a root-mean-square (RMS) calculation.
