The M1-3VR4B.0005.570DD is a 4-digit meter for length and level measuring via potentio- meter >1kOhm to <1000kOhm and a visual limit value monitoring via the display. The con- figuration happens via three front keys or via an optional PC-software. Selectable software functions, a direct limit value adjustment in operating mode and the compact installation depth of 74mm complete the solid device concept
