Used for measurement of positive or negative voltages up to 40,000 V, HVM40B features LED display and solid-state design. Dual range measurement provides increased resolution below 20 kV, and 10 giga-ohms input impedance minimizes circuit loading to promote accuracy. Along with various power cords for worldwide use, digital voltmeter features retractable feet, optional tilt handle, and optional rack mount hardware to accommodate environments ranging from lab bench to field.
