* The CW120 Series is compact in size (117 x 161 x 51 mm (W x H x D)), making it ideal for installation in cubicles and inside distribution panels. Installation is even easier with the magnetic case (93023).
* Although the CW120 Series is small, it has a large backlit LCD.
* A new addition to the clamp lineup is a small-diameter current clamp (model 96033, capable of measurements in the range of 5 50 A) for measurements in tight spots and locations where many wires are jumbled together.

* The CW120 Series can be used for voltage measurements up to 495 V.
* A variety of connection types are supported, from single-phase 2-wire to three-phase 4-wire (CW120: three-phase 3-wire model; CW121: three-phase 4-wire model).
* Continuous measurement integration (accurate measurements can be obtained even if there are large load fluctuations)
* Plus/minus signs are shown for reactive power and power factor.
* The data saving interval can be set in the range of one second to one hour.
The setting software allows you to set CW120 Series measurement conditions through a PC and save measurement data on a PC when the unit is connected to the PC through RS-232 or RS-485 port.
