This digital panel meter measures and displays both voltage and current and is based on a unique design using a single 3-digit display. An on-board slide switch is used to switch between the two values (voltage and current). When displaying the current, the letter "A" is displayed after the value to visually indicate that the panel meter is in the ammeter mode. It is an ideal addition to any laboratory DC power supply. It measures DC voltages from 0 to 99.9V (resolution of 0.1V) and DC current from 0 to 5.00A (resolution of 10mA).
