Stationary Meter Test Systems

Today Meter Test Technology is much more than only testing accuracy and functionality of a conventional electricity meters. With implementation of SmartMeters a complex test and data management system is required. – It’s a good thing to have experts by your side.

Power Sources

Power Sources of MTS-series based on digital amplifier modules combined with frequency generator and reference device are the MTS source system. Single-phase systems (MTS1xx) or three-phase systems (MTS3xx) from 1 to more than 40 test positions are available.
