    1. Brief description / 2. Assembly 1. Brief description The panel instrument M1-1C6 is a 4-digit device for temperature metering via Pt1000- sensors and a visual limit value monitoring via the display. The configuration happens via three front keys or via the optional PC-software PM-TOOL. An integrated programming interlock prevents unrequested changes of the parameter and can be unlocked again via an individual code.
