Device short description

The UMG 96 RM is a multi-functional network

analyser, which:

• Measures and calculates electrical

variables such as voltage, current,

frequency, power, energy, harmonics

(up to the 40th harmonic), etc. in building

installations, on distribution units, circuit

breakers and busbar trunking systems.

• displays and saves measurement results

and transmits them via interfaces.
