General
Embedded Web server
■■■
Use a standard Web browser to monitor and manage the meter over the network, Internet
TOU metering support
■■■
Time of usage can be set up to support 4 different schedules
Firmware flash update support
■■■
Enables you to flash the meter with the latest firmware updates
Self-learning capability (characterizes “normal” per circuit)
■■■
The meter can automatically adjust to the environment and alarm only when
“real” events occur
Power, Energy and Demand
Voltage, current: per phase minimum, maximum, average, trend graph analysis,
export, print
■■■
Review voltage and current trends, export, print and analyze parameters right on the meter
or external software
Energy and demand plot comparisons month-to-month, week-to-week
■ ■ ■ Plot two months or two weeks for vivid energy or demand comparison
Power: power factor, apparent, real, reactive, frequency
■■■
Review power usage and power factor and avoid potential PF penalties
Energy, demand: forward, reverse, net, sum, tou, profile, previous month
comparison, graph analysis, export, print
■■■
Keep track of your energy usage, compare time of usage and usage against previous month,
identify peaks to conserve energy usage
Power Quality Analysis
Statistical analysis (min., max., average)
■■■
Review statistical trends, identify past and future problem areas
Sag and swell monitoring, management and recording
■■■
Capture electrical sags and swells and analyze the waveforms
Symmetrical Components: Zero, Negative, Positive
■■■
Analyze possibly unbalanced three-phase power systems
Low frequency transient detection and capture
■■■
Capture lower frequency transient waveforms for retrospective analysis or e-mailing
Sampling rate, maximum samples/cycle 4096
