Power meters have innovative functions

For performing stand-by-power, Energy Star, IEC62301, battery-charger, and other power measurements, the low-cost WT300 series digital power meters offer updated and innovative measurement functions, such as the Auto Range feature, which optimizes the range setting for maximum accuracy measurements, and the Average Active Power function, which makes it possible to measure power consumption under greatly fluctuating power conditions.

The WT300 family consists of three models: the single phase WT310 with the capability of measuring currents from 50 μA to 20 A rms, the single phase WT310HC with current ranges from 1 to 40 A rms, and the two element or three element WT330 unit for split- or three-phase circuits, which has ranges of 0.5 to 20 A rms. All models have voltage ranges from 15 to 600 V rms. (From $3,875 — available now.)
