With basic power accuracy of ±0.02% reading, DC and 0.1 Hz-1 MHz measurement bandwidths, and up to four input elements, the WT3000 provides higher-accuracy measurement of I/O efficiency.
*As compared to Yokogawas WT2000
In developing the WT3000, Yokogawa focused on improving efficiency in two basic areas. One goal was to obtain highly precise and simultaneously measurements of the power conversion efficiency of a piece of equipment. The other objective was to improve equipment evaluation efficiency by making simultaneous power evaluations and tests easier and faster.
The Yokogawa WT2000 was very popular with users and considered highly reliable because of its high precision and excellent stability. The WT3000 is based on a measurement system which combines the measurement technology used in the WT2000 as well as other WT Series models. With the WT3000, we made further improvements to the basic performance specifications for even better functionality and reliability. We are confident users will appreciate these improvements to power and efficiency measurements thanks to the new power control technologies we have introduced.
The WT3000 is the first model in the WT Series which is standard- equipped with a PC card slot (ATA flash card slot). This interface allows data to be saved quickly, so data processing time is reduced. The WT3000 is also standard-equipped with a GP-IB port. In addition, a serial (RS-232) port, Ethernet port, and USB port are available as options. The variety of interface choices allows customers to use the best interfaces for a wide variety of equipment, media, and network environments.
Yokogawa's highest-precision power analyzer *1 The WT3000 has the highest precision of all the Yokogawa power analyzers in the WT series. The models in the WT series are designed to meet a wide variety of user needs. The WT300 series is a high price-performance series which is very popular in production line applications. The WT1800 allows measurement data to be viewed in a variety of ways, including numerical value display, waveform display, and trend display capabilities.

Measuring Conversion Efficiency of Power Conditioner
Energy consumption in low-power and standby modes is an important issue due to increased awareness that energy resources are becoming limited and demand for energy-saving household electrical appliances continues to grow. IEC62301 Ed2.0 (2011) and EN 50564:2011 define standby mode as the lowest energy consumption of an appliance not performing its main function, when connected to the mains. IEC62301 Ed2.0 (2011) defines test methods and requirements for both the mains supply and the test equipment. It is crucial that design and test engineers choose highly accurate power measurement tools to confirm that their devices meet these requirements.
