"The 2533-11 is a power meter from Yokogawa. A power analyzer, or power quality analyzer, can take accurate measurements of direct current (DC), alternating current (AC), voltages, phase rotations, and power in many different types of electronic equipment. Power analyzers are for monitoring any device that consumes, transforms, or generates electricity.","Additional Features:","The Yokogawa 2533-11 Digital Power Meter is an outstanding solution to accurate effective power measurement of distorted waveforms. The 2533-11 is ideal for use on production lines and in research and development. The 2533-11 features faster response time and a greater number of features than concentional models. A built-in photo coupler provides complete isolation between the power meter input and output circuits. With its high dielectric strength and high resistance to external noise, this meter offers stable and reliable operation. Simultaneous Display of 3 Measured Values Three values among measured or computed values are simultaneously displayed: voltage, current, power in each phase or total power, apparent power, reactive power, power factor, and more.","True rms measurementThe 2533 can measure triangular and square as well as distorted waveforms based on the \"log RMS-to-DC conversion system\", and also measure DC voltage superimposed on AC voltage","High precisionThe voltage, current and power can be measured with high accuracy: +\/-0.1% of rdg + 0.1% of range","Wide band of DC, 10 Hz to 20 kHzHaving a DC range and frequency range of 10 Hz to 20 kHz, DC\/AC model measures DC current and AC current in a single-phase circuit, voltage, current and power-that AC is superimposed on DC-are also measured, the instrument is best suited for measuring power of distorted wave and inverters of every kind","Versatile computing functionsPowerful computing functions include V (mean value of line or phase voltage), A (mean value of phase current), VA (apparent power), var (reactive power), and PF (power factor)","PT and CT scalingEven when PT or CT is externally mounted, the voltage, current, power, etc can directly be read through scaling function","Dielectric strength3,000 V AC for one minute between the input terminals and case, and between the input and output terminals and power line","High input impedanceThe input impedance is very high. So, the meter can accurately measure even very low power levels that conventional analog instruments have not been able to measure until now","GPIB and RS-232-C interfaces (optional)For data communications, the GPIB or RS-232-C interface is available. Full remote control is available for data output and range, function, etc. from external","Integration and frequency measuring function (optional)Current and power integrating function, and source frequency measuring function"
