Brief description of device

The devices UMG 96 RM-P/-CBM are

multifunctional network analysers, which:

• Measure and calculate 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.

• Display and save measurement results and

transmit them via interfaces.

The UMG 96 RM-P and the UMG 96 RM-

CBM:

• have the same construction type.

• differ due to the additional Profibus

interface of the UMG 96 RM-P.
