Glossary
kWh: Kilowatt hours; kW x demand interval in hours.
KYZ Output: Output where the rate of changes between 1 and
0 reflects the magnitude of a metered quantity.
LCD: Liquid Crystal Display.
LED: Light Emitting Diode.
Maximum Demand: The largest demand calculated during any interval
over a billing period.
Modbus ASCII: Alternate version of the Modbus protocol that
utilizes a different data transfer format. This
version is not dependent upon strict timing, as is
the RTU version. This is the best choice for
telecommunications applications (via modems).
Modbus RTU: The most common form of Modbus protocol.
Modbus RTU is an open protocol spoken by many
field devices to enable devices from multiple
vendors to communicate in a common language.
Data is transmitted in a timed binary format,
providing increased throughput and therefore,
increased performance.
Network: A communications connection between two or
more devices to enable those devices to send to
and receive data from one another. In most
applications, the network is either a serial type or
a LAN type.
NVRAM: Nonvolatile Random Access Memory: able to
keep the stored values in memory even during
the loss of circuit or control power. High speed
NVRAM is used in the Nexus® meter to gather
