The M1-1VR4B.0005.570CD is a 4-digit meter for length and level measurement via potentio- meter >1 kOhm up to <1000 kOhm 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 minimal installation depth of only 38mm complete the solid device concept.
