Brief description of device

Connection variants for voltage measurement

The UMG 96 RM-E is a multi-functional net-

work analyser, which

3p 4w

• measures and monitors residual currents

(Addr. 509 = 0, standard setting)

(RCM) and currents at the central grounding

point (CGP). The residual current monitoring

is carried out via an external residual current

transformer (30 mA rated current) on the

current measurement inputs I5 and I6.

• 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.

The UMG 96 RM-E is operated with buttons 1 and

2, whereby the following distinctions are made:

• Short press (button 1 or 2):

Next step (+1).

• Longer press (button 1 or 2):

Previous step (-1).
