Chroma's new series 66200 Digital Power Meter is designed for single-phase measurements of AC power signals and related parameters common to most electronic products. Instead of traditional analog measurement circuits the 66200 uses state-of-the-art DSP digitizing technology. The internal 16 bits analog/ digital converters with sampling rates of up to 240KHz provide both high speed and high accuracy measurements which is unprecedented within the industry for this class of power meters current on the market.

The instruments include a four part display with 7-segment LED front panel readouts. Users can easily select desired parameters and readouts at a touch of a button. Instruments also include optional remote control using USB or GPIB interfaces via rear panel connections. The 66200 is packaged in a 2U high, half rack enclosure suitable for benchtop or system integration.

The Model 66202 includes a 2-shunt design to provide highly accurate readings for both low and high current measurements. In addition to the parameters measured by Model 66201, the 66202 includes Inrush current, Total Harmonic Distortion of V/I, and Energy measurements. With these practical functions, The Model 66202 is suitable for the most demanding of R&D and quality control departments.

66200 series provides 3 methods for measuring. A simple Average method can provide a visual stable value but it still may lose some transient data. A Window Mode method that calculates all data within the user-defined window time is recommended. An accumulated energy approach method (i.e. Integration method) for power measurement is also provided. It calculates active power value by integrating energy is suitable for ENERGY STAR measurement requirement.
