Flicker is the sensation that is experienced by the human visual system when it
is subjected to changes occurring in the illumination intensity of light sources.
IEC 61000-4-15 and former IEC 868 describe the methods used to determine
flicker severity.
Wiring and Hookup configuration for the Nexus 1260/1270.
Measuring values of the fundamental current and voltage and percent of the
fundamental.
Energy indicator on the face of the Nexus 1250/1252; pulses are generated per
the programmed K e value.
Energy indicator located on the upper left side of the face of the Nexus 1260
/1270 meter; pulses are generated per the programmed K e value.
Any of the natural numbers, the negatives of those numbers or zero.
An optional modem within the meter's enclosure that connects to the RJ-11
telephone connector.
In the Nexus Modbus Map there are gaps between Registers. For example, the
next Register after 08320 is 34817. Any unmapped Register stores no
information and is said to be invalid.
An updated version of the CBEMA Curve that reflects further study into the
performance of microprocessor devices. The curve consists of a series of steps
but still defines combinations of voltage magnitude and duration that will cause
malfunction or damage.
kWh per pulse; i.e. the energy.
kilowatt hours; kW x demand interval in hours.
Output where the rate of changes between 1 and 0 reflects the magnitude of a
metered quantity.
Liquid Crystal Display.
Light Emitting Diode.
In Modbus communication, a Master Device initiates and controls all
information transfer in the form of a Request Packet to a Slave Device. The
Slave reponds to each request.
The largest demand calculated during any interval over a billing period.
