Brief description of device

The UMG 96 RM-EL is a compact,

multifunctional network analyser that

• is designed for low voltage and medium

voltage distribution systems.

• measures and calculates electrical variables

such as voltage, current, power, energy,

harmonics, etc. in building installations,

on distribution units, circuit breakers and

busbar trunking systems.

• displays measurement results and forwards

them via interfaces.

• captures the energy consumption for cost

centre analysis.

• is used as a measured value transducer

for building management systems or PLC

(Modbus).
