This powerful Power Analyzer was designed to help R&D to create a new generation of environmentally friendly products and technologies. It has been developed and produced in our ISO14001 approved facilities, in accordance with YOKOGAWA's "Guidelines for Designing Products for the Environment", and our "Criteria for Environmental Assessment in Product Design". We have adopted these Guidelines and Standards to help protect the Global Environment, consistent with the focus of the Third Conference of the Parties to the United Nations Framework Convention on Climate Change (COP3, Kyoto, December 1997).
|The PZ4000 was selected by
TM Magazine for the
Best in Test 1999.
Test & Measurement's award recognized the PZ4000 as a powerful analyzer due to these features:
Measured voltages and currents are sampled at high speed (maximum 5 MS/s). Power is calculated from the sampled data along with accurately displayed waveforms
|Output signal check for an inverter-driven 3-phase motor
||Check using zoom function to determine whether pulse waveforms are fully acquired during low-rpm operation
Measurements can be made over a wide frequency range (DC up to 2 MHz), making it possible to measure power loss on electronic components, high-frequency lighting equipment, and other devices.
|Measurements on inverter lighting equipment with a fundamental wave of approximately 50 kHz
||Loss measurement during high-frequency capacitor driving (500 kHz)
Internal memory (maximum 4 M words) stores your measurements. You can calculate and display voltage, current, and power values for specific portions of the total memory (equivalent to 100 k words of data). The display makes it easy to see how the load fluctuates with time.
|Inrush current measurement in an inverter-type cleaner
||Efficiency evaluation when inverter output is turned on in a cooking machine using induction heating
The PZ4000 lets you analyze harmonics (up to 500th order) using high-speed sampling. With the FFT calculation function, you can perform spectrum analysis in the high-frequency range (up to 2.5 MHz). Analysis results are displayed on spectrum graphs. In addition, vectors showing the fundamental components of distorted waveforms can be displayed to give a visual presentation of the load balance in a 3-phase power supply system.
