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.
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.
Users can set a current level for triggering the starting point of measurement. Another parameter, Delay, can help users to ignore the peak value B after the trigger point A. The parameter, T, can let users set a time period for measuring the peak value C during Time T.
The 66200 Series includes an easy to use software package for remote operation, display, and control. It displays measured value, voltage/current waveform, parameters, and time relative charts. The Recording function allows users save data to a file for long duration measurement. This makes it is easy to meet ENERGY STAR measurement requirements for accumulating true power values at an interval of 1 reading per second and recording the average (arithmetic mean) value observed during a 5 minute period. This software can also perform pre-compliance tests for standard IEC61000-3-2 current harmonic limitation.
Another Average Efficiency Test Software package integrates Chroma’s AC Sources, electronic DC Loads and 66202 power meter for testing average efficiency of power supplies automatically. Users can set the loading and test steps on the software. After finishing the test, it will generate the results and test reports.
An optional test fixture – A662003 (250V/15A) – is available to let users connect cables easily. Users can choose an external Current Transformer 50A/100A to extend the current measurement range on the 66202.
