The M1-6VR4B.0005.570BD 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. For further evaluation, 2 switch- ing points are available. Selectable software functions and a direct limit value adjustment in operating mode complete the solid device concept.
