    1. Brief description 1. Brief description The panel meter M2-11 is a 5-digit device for direct current/direct voltage signals and a visual threshold value monitoring via the display. The configuration happens via four front keys or via the optional PC software PM-TOOL. An integrated programming interlock prevents unrequested changes of the parameters and can be unlocked again by an individual code.
