Get a view of energy consumption
It is essential to measure energy and manage consumption of each sector such as facility and production line for your energy saving activities and to minimize loss.
Contribute for improving productivity
Constantly analyze productivity by managing unit consumption. Managing voltage, current, electric power and power factor makes for good maintenance of production facility.
Moreover, you can check operation management loss and enhance productivity.
Discover of electric power waste
Measure and collect data of electric power consumption by short period. The CW240 can figure out load of production process, and has the ability to check wasteful time and current flow of standby load current.
Detect voltage fluctuation
When trouble occurs on supply side of electric power, instantaneous voltage drop can affect quality of produced goods at the factory. The CW240 is useful for collecting data such as voltage fluctuation to prevent such problems.
The CW240 power meter is a complete tool for enhancing energy efficiency, finding areas for improvement and assessing equipment lifecycles. The meter provides in-depth information on how an item of equipment, an area of a plant or a complete facility is operating that goes beyond simply measuring power usage.
By using the supplied clamp-on components and probes, users can better determine maintenance, repair and replacement schedules for equipment such as transformers and motors. Information is provided with respect to load factors and demand factors, as well as current/voltage fluctuations at motor start-up.

Power Investigation Improves power Efficiency Through Detailed Data Collection
Measurement of Instantaneous Value
The CW240 can be used to carry out investigation regarding renewal of electric equipment such as transformers in building, check load factors and demand factors, and to check current/voltage fluctuation at motor start-up.
Power Quantity Measurement: For Power-Saving Diagnosis and Data Collection for ISO14001
The CW240 can measure and display the power quantity consumed up to the specified time (from the start of integration until the end).
Demand Measurement: For Review and Investigation on Contract Demand
Normally, the demand time limit is set to 30 minutes in the contract with a power company. However, the CW240 allows you to set the desired demand time limit in units of seconds/minutes
In many cases, inverter power supplies are used to drive air-conditioners and compressors. These power supplies cause distortions in voltages and currents, leading to malfunctions and power loss. Therefore, investigation and control of influences on the main power supplies by harmonics is necessary
Voltage Fluctuation Measurement
The CW240 detects dates/times of when fluctuations occur, fluctuation type, channels where they occur, rms values, and periods between start and end. The voltage threshold is set, and fluctuations exceeding the threshold are detected
Measures Loads in Four Systems Simultaneously.
The CW240 enables simultaneous measurement of loads in four systems in the case of the single-phase 2-wire system, and in two systems in the case of the single/three-phase 3-wire system (common to voltage). Current clamp probe/range can be set for each system.
