WT200 Digital Power Meter (253421) (EINGESTELLT)

To change the voltage range on element 1 to 30 V, send the "CONFIGURE:VOLTAGE:RANGE 30V" command to the measuring instrument.To change the current range on element 1 to the 1 A range, send the "CONFIGURE:CURRENT:RANGE ...

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 ...

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 0 (UPD) of this register. However to do ...

You can determine whether data was updated by performing a serial poll and referencing the status byte.Bit 0 of the status byte (D101) changes to 1 when data is updated. When bit 0 changes to 1, bit 6 (D107) also ...

NO, you should not use the instrument with both the direct input and external sensor terminals wired. Doing so will put the user at risk of electric shock and could damage the instrument. This is because the ...

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 "OF1,1,1" commandThis command sets the voltage value (V) from element 1 to output to channel 1 (from among the 14 output channels), and causes the voltage of element 1 to be read out. In the same manner, make ...

Send the "MEASURE:NORMAL:ITEM:PRESET:CLEAR" command to the measuring instrument. This command turns all items for output OFF. Therefore no items will be output if you send the "MEASURE:NORMAL:VALUE?" command. Send the ...

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 ...

• Binding posts on the direct current input terminals
• Prevent an open current circuit and safety hazards

 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 ...

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 ...

• 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 ...

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 ...

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 ...

When making a WT230 Digital Power Meter RS232C connection using GateWT, please verify the following RS232C communication settings on the instrument: Mode = 488.2 Hand = 0 For = 0 Baud Rate = 9600 Terminator Cr+Lf Even though you can run ...

• A9105ZG: Black Current Knob Set of 2 B9292GX: Pad (Studder) Set of 10

The D/A output of the WT230 Power Meter uses a 24-Pin Centronics type connector. For additional informating regarding the 24-Pin Centronics Connector, please refer to the attached PDF and click on the link below.

The Precision Power Analyzer WT3000  D/A output terminal is electrically isolated from the case. For all other models, the D/A output terminal is connected to the case.

The value depends on the model of the power analyzer. For Precision Power Analyzer WT1000, WT2000, WT100, and WT200, it is fixed to the fundamental wave. For power analyzers with 7 segments LED, the relative harmonic content is fixed to the ...

You can read the average active power during continuous integration mode (just before the integral resets) for the WT230, by monitoring the status of the ITG or ITM bits of the extended event register.   Bit 1 ITG is ...

Although WTViewer is not officially supported under the Linux environment, users have successfully done so using WINE (flavor of Linux) via RS232. For connectivity to WT210/WT230, WTViewer requires that the meter be set ...

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 ...

Although Yokogawa does not have any official recommendation for USB to Serial converters, it is possible to use some USB to RS232 DB9 Adapter Cables. If you choose to use a laptop PC without RS232C port, please use ...

Yes, the WT210 will meet or exceed all requirements set by the Energy Star guideline. Please see the attached documents for more details.
