Energy meter readings
UMD 705 has an embedded three phase, four-quadrant energy meter with automatic meter reading
functions and multiple programmable tariffs (Time-of-Use, TOU). The instrument registers active
energy (EP, EP+, EP-) and reactive energy (EQL, EQC or EQC+, EQC-, EQL+, EQL-). According to
the configuration of meter readings are shuffled to the respective tariffs. It automatically provides
summaries per phase. For star connections and single phase measurements it can also register
energy for each phase separately.
Meter data readings can be downloaded and analyzed in ENVIS or via the standard ModBus protocol
in any other system.
