The M2-device is a 5-digit meter for the measuring of high direct voltage signals up to 600VDC and visual limit value monitoring 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 2 switching points are available. Selectable software functions, a direct limit value adjustment in operating mode and the compact installation depth of 89 mm create a solid device concept.
