The Volcraft DVM-330G DC Digital Voltmeter Module is a panel meter with DIN dimensions for installation in mains or laboratory devices and control panels. DIN dimensions of 72 x 36mm and 13mm digit height. With low-battery warning, data hold function and display options for the following units: °C, °F, V, A, µ, m, M, k, O and backlight. Virtually any measuring range may be achieved by simply adding resistors (voltage divider, shunt), example: Electrical connection via solder tabs. * Assembly dimensions 33 x 68mm * Green colour * Input resistance 100 MΩ * 100MO
