The M2-1VR5B.0004.570BD is a 5-digit meter for measuring of AC current /AC voltage signals TRMS and a visual limit value monito- ring via the display. The configuration happens via 4 front keys or via an optional PC-software. For further evaluations options like one analog output, one digital input and two switching points are available. Selectable software functions, a direct adjustment of the limit value in operating mode and the compact installati- on depth of 89mm create a solid device concept.
