This dual digital panel meter measures and displays both voltage and current at the same time. It is ideal for measuring the voltage and current of your laboratory DC power supply. It includes two 4-digit 0.7" (18mm) high LED readouts. It can measure DC voltages from 0 to 99.9V (resolution of 0.1V) and DC currents from 0 to 5.00A (resolution of 10mA). The circuit incorporates a DC regulated power supply.
