Reference meter and source in one

Our definition of Test Systems is a Reference Meter with integrated source. Test systems are particularly usable for testing meter installations with defined current and voltage and only one single device should be used. Brand new in our product range is the MT786 standard set – a complete predefined package for on-site meter testing with the most common accessories.

An overview of the entire MT series, consisting of test meters, sources and test systems, can be found in our “MT series leaflet”.
