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
The EM 3000 series has three different models for different applications:
Power & Energy Monitor EM 3360
- Voltage: Phase to Phase and average, Phase to Neutral and average, 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 7 seasons for energy parameters
 Tri-vector Monitor EM 3480
All features of EM 3360 meter plus
- EB Meter cross-check

- 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 All features of EM 3480 meter plus
- 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

In our earlier system of conventional meters the error reading was to the extent of 6-8% due to less sensitivity and accuracy...but now with the Conzerv meters we can proudly say that we prepare an exact Energy balance sheet with error less than 1%
