o help you with your energy conservation needs, Yokogawa introduces its low-cost clamp-on power meters to provide an easy-to-use tool capable of measuring power values and instantaneous values. These meters can be used with current clamps ranging from 50A to 3000A, including the new small diameter current clamp (96033) for measurements in tight spots. Compact in design, making it ideal for installation inside distribution panels, the CW120/121 also has a large, backlit LCD. This unit can be used for voltage measurements on systems up to 495V. Continuous measurement integration allows accurate measurements even with 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. Each measures 117 x 161 x 51 mm, weighs 600 grams, and ships complete with power cord, 3 voltage probes (91018), and users manual. The Complete Power Meter Package (424-257) includes 4 voltage probes (91007), AC power adapter (A1022UP), power supply cable (93030), carry case (93022), software (AP140E), 16 MB flash memory card (97030) and RS-232 cable (91011).
