The M1-7VR4A.0005.770CD is a 4-digit meter for length/level measuring via potentiometer >1kOhm to <1000kOhm and a visual limit value monitoring via the display. The configuration 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 54mm complete the solid device concept.
