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
Display Examples:
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.
Display Examples:
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.
Display Examples:
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.

You can use the "STATUS:ESSR?" command to access the extended event register and determine whether the data was updated. You can judge the data update status by referencing bit 1 (DAV) of this register. However to do ...
Send the appropriate command as shown below to your instrument, then read in all the data that is returned. PZ4000: "NUMERIC:NORMAL:VALUE?" WT1600: "NUMERIC:NORMAL:VALUE?" WT100/200 series ...
Send the "NUMERIC:FORMAT:ASCII" command This sets the data format for the data you want to read out. Measured data read out using the "NUMERIC:NORMAL:VALUE?" command is output as an ASCII string. Send the ...
To change the voltage range on element 1 to 30 V, send the "INPUT:VOLTAGE:RANGE:ELEMENT1 30V" command to the measuring instrument.To change the current range on element 1 to the 1 A range, send the ...
The waveform may actually not be a pure sine wave. Even though a 50/60 Hz sine wave is expected, the following factors may be involved: The waveform is slightly distorted (harmonic components are mixed in) Small ...
The measurement intervals of the measured I/O data must overlap exactly. Check the sync source setting. For example, route the input to a three-phase device under measurement to input elements 1-3 on the power meter, ...
Check for differences in the specifications or features of the instruments. For values that do not match when inputting a 50/60 sine wave Check whether the value is within the specifications (error) of each power ...
In the three-phase three-wire, or 3V3A wiring scheme, the phase angle of voltage and current input to each input differs from that of the actual load because it is the line to line voltage that is measured. In ...
Check the Synch Source and Frequency Filter settings When a single-phase signal being measured fluctuates around power factor of 1.Slight fluctuations in the measured values of voltage, current, and power can cause a ...
The following may be causing the problem. 5V may have occurred during rating. Check the range setting again. DA output error can affect the values when the input is smaller than the rating. Have you checked the error ...
It is possible to measure the phase difference by using the function φU1(1)-U2(1) in Hamonics Measurement Mode.In this mode, if the wiring pattern is set to 1P2W, the PZ4000 will display no value (----). It is ...
The difference in measurement values can be attributed to the difference in calculation methods for normal mode and harmonic mode. The voltage, current, and power in normal mode are displayed as the total of the ...
