Class A measurement devices are certified in accordance with IEC 61000-4-30. This standards provides detailed specifications that a network analyzer must meet so that the results can also be used in cases of dispute. The standard defines the necessary parameters, suitable measurement methods, accuracy, and bandwidths. Consequently, results can be easily reproduced and compared.

Reliable operation of modern plants and systems always requires high supply reliability and good power quality.

UMG measurement devices reliably record, analyze, and document all disturbance variables such as harmonics current, unbalances, transients, voltage dips, overvoltages, flicker, phase shifts, and reactive power.

BACnet is one of the most important communication standards for building services engineering, primarily because of its compatibility with a wide variety of hardware and uniform, cross-vendor communication.

As soon as a UMG measurement device has received its BACnet ID and is integrated into the network, it is recognized by the system and displayed in the browser. This makes configuration very easy.

The web server on the measurement device provides a wide range of data in a clearly structured format. Users do not need to install any software on their PC, a standard web browser is sufficient. Users enter the IP address of the measurement device in the URL window of the browser and the homepage of the measurement device appears on the screen. In addition to the modern homepage, apps are also available for an extended range of functions.

Powerful residual current monitoring (RCM) detects residual currents at the initial stage, before they lead to system failures or even fires. It is already integrated into certain UMG measurement devices. The required RCM measuring current transformers can even be retrofitted if required. Continuous RCM monitoring significantly increases system safety and availability. In certain applications such as data centers, residual current monitoring is mandatory due to high availability requirements.

Modbus RTU devices that are connected to the master device as slaves can be very easily integrated into an Ethernet architecture via the Ethernet Modbus gateway. For devices with an identical file format and matching function codes, this is possible directly via the Modbus RTU interface.
