The AC Power Input in all Yokogawa instruments is designed as a 3-pin connection (one of which is a GND pin). In some parts of the world, PCs are sold with AC power cables that are 2-pin. Often times this means the ...

• WT1800 High Performance Power Analyzer, WT500 STORE functions can only be used to record NUMERIC data   
• WT1600, WT3000 STORE functions can be used to record both NUMERIC and WAVEFORM data

Yes, the AUX inputs on the WT1800 can be used in the Math functions.   For example, if you wanted to measure a DC bus input using the AUX inputs (input elements not connected), you would scale one of the AUX inputs to ...

The WT1800 and WT3000 series digital power analyzer offer two calculation methods, Type1 and Type3, for apparent and reactive power.  Type1:The WT will first calculate the RMS voltage Urms, current Irms, and active ...

The following product tutorial guides have been created for the WT and PZ Series Power Meter and Analyzer instruments and are available for download. Each tutorial contains quick and easy steps to help you get started ...

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 ...

• Power analyzers/power meters
• Binding posts on the direct current input terminals
• Prevent an open current circuit and safety hazards

A quick and simple way of accessing the measurement data from a CSV file saved by the WT1800 is to use the MATLAB import wizard. In MATLAB, simply click on File > Import Data.... You can also use the MATLAB built-in ...

To use USB interface on the WT500 and WT1800 Power Analyzer from NI LabVIEW environment, you will need to use the USB driver from National Instruments. This USB driver is usually installed when you install NI-VISA and is called the ...

To measure inrush current on the WT1800, you will need to define and use the IPPEAKMAX() user defined function in combination with the Max Hold feature. A complete tutorial with instrument settings and how-to procedures ...

To programmatically read all 500 harmonic orders measurement values, please use the ":NUMERIC:LIST" command set. The maximum number of items for the :NUMERIC:LIST:VALUE? command is 64.  However, 1 LIST ITEM can ...

 You can not use LabVIEW and WTviewer to communicate with the PC using same USB driver. The USB driver for LabVIEW and the USB driver for WTviewer is different. Yokogawa's YKMUSB driver is used by WTviewer ...

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 ...

The peak value and crest factor may be unstable if they have not been captured accurately. If the peak value is not stable, neither will the crest factor be stable. The cause is the difficulty in capturing the narrow ...

Output function: HArWhen the default output item is set to 1, the printout time for up to the 50th order is about 116 seconds. The printout time for up to the 25th order is about 75 seconds. Output function: HArWhen 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 ...

• Check the "Sync Source" and zero cross filter (frequency filter) settings.
• For the WT3000, "Sync Source" setting is irrelevant if the data update rate is 250 ms, 500 ms, 1 s, or 2 s.

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 ...

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 ...

• Power Analyzer/Power Meter 
• In the case of three-wire, or 3V3A wiring, or three phase power source, they do not match because it is the line to line voltage that is measured

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 ...

• WTViewer Save Setting feature will only save WTViewer setting information
• Will NOT save the setting information of the instrument

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 ...
