The EM 3000 series meters are used to measure:

	Voltage: Phase to Phase and average
	Voltage: Phase to Neutral and average
	Voltage: Neutral to Earth
	Voltage: Phase angle
	Current: Phase-wise, Average and Neutral Current
	Current: Phase angle
	% Total Harmonic Distortion of voltage & current wave forms phase-wise

EM 3000 series has 3 different models, choose by applications:

Power & Energy Monitor EM 3360 Accuracy Class 0.2 $580.00

	Voltage: Phase to Phase, average, Phase to Neutral, average,
	Voltage: Neutral to Earth.
	Phase angle: Voltage and Current phase wise
	Current: Phase-wise, Average and Neutral Current
	% Total Harmonic Distortion of voltage & current wave forms phase-wise
	Monitoring of all power & energy parameters - total as well as phase wise
	4 high and 4 low profiles for instantaneous parameters with day, date and time
	Optional TOU for 8 intervals and 6 seasons for energy parameters

Tri-vector Monitor EM 3480 Accuracy Class 0.2 $790.00

	EB Meter cross-check
	Monitors demand parameters: Instantaneous & maximum demand, with day, date & time
	Synchronizes automatically with EB meter
	Records High-Low profile of maximum demand
	Generates Demand Profile at 19 Demand Levels for setting realistic demand targets according to user-programmed Demand Level 0 and step size
	Optional TOU for 8 intervals & 7 seasons for energy and demand parameters

Smart Demand Controller EM 3460 Accuracy Class 0.2 $990.00

	User programmable upper limit and lower limit of kW or kVA parameters, essential load and prediction interval for sophisticated demand control
	Demand intervals selectable from 1 to 30 minutes
	Demand control through unique predictive technique and sliding window integration which leads to: Reduced energy losses, improved load factor & minimal disruption in operations
	3 changes over potential-free control outputs for: Predicted demand exceeds target, demand exceeds target & restore load
	Spare load and predicted demand parameters gives advance warning for planned demand control
