D000044352 en g – E230 Residential Electricity Meter – ZxR100xC/ZMR100xR – User Manual
The meters have the following basic characteristics:

Recording of active/reactive energy in one or more tariffs

External tariff control via control input terminals

Display of data with a liquid crystal display (LCD)

Landis+Gyr's proprietary application-specific integrated circuit
(ASIC) measurement technology using one shunt measuring
element per phase

Compliance with accuracy classes 1 and 2 according to IEC

Compliance with accuracy classes A and B according to MID

Flexible measuring system through the definition of different
variables by software (single parameterisation by manufacturer)

Correct measurement even with the failure of individual phases or
when used in two- or single-phase networks

Wide range of measurement from starting current to maximum
current

Serial interface with optical input/output

For direct readout of meter data

For communication with an extension

CS and RS485 interface for remote communication of data

Pulse output for transmission of constant pulses

Relay output for switching external circuits (ZMR100xR only)

Installation aids

Indication of the presence of phase voltages, rotating field
and direction of energy

Power indicator

Storage of additional information, such as operating times (readable
via optical interface or, if present, the CS or RS485 interface).
The E230 ZxR100xC and E230 ZMR100xR meters record active and
reactive energy consumption primarily in three-phase four-wire
networks. The meter can operate on one phase (any phase and neutral),
two phases (any two phases and neutral) and three phases with or
without neutral. In addition, E230 ZxR100xC can also operate on three-
phase delta configuration (F-Circuit). For this purpose, the meters are
directly installed in the supply line by the energy supply company and
are read regularly for energy charging purposes. They are used
according to the technical specifications stated in the respective data
sheets and in conjunction with this document.
