Model 66202 Digital Power Meter 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.
Chroma’s Digital Power Meters are designed for both single-phase and multiple phase measurements of AC power signals and related parameters common to most electronic products. Instead of traditional analog measurement circuits the 66200 Digital Power Meter uses state-of-the-art DSP digitizing technology. The internal 16 bits analog/digital converters with sampling rates of up to 200KHz 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 series provides 3 methods for measuring. A simple Average method provides a visually 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 for best accuracy. 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.
66202 Digital Power Meter can measure voltage and current Total-Harmonic-Distortion (THD) directly. For some requirements of ENERGY STAR, users need to verify the THD of AC supply voltage not to exceed 2%, up to and including the 13th harmonic. The Model 66202 also provides a function to define a user-specified distortion order “n” for measuring harmonic distortion.
