La description

The WTViewerFreePlus software captures measured numeric values, harmonic values, and waveform data. Users can view and save data on a PC using USB, GPIB, RS-232, or Ethernet.
You can use WTViewerFreePlus to connect WT300 / WT300E series power meters (hereafter referred to as WT) to a PC and:
  • Retrieve, display, and save data that the WT has measured and setup parameters
  • Remotely control the WT
Setting Window
As well as using the WT300 / WT300E series front panel to set up the power meter, users can quickly set up preferred conditions. It also shows setting parameters and status at a glance. For instance, you can set up the range-skip function (range-configuation setting) and specify the maximum order for the THD calculation.
Measurement Window
The software can display items which cannot be shown on the display of the WT300 / WT300E series, such as multiple numeric measurement parameters, the harmonics data of each other, bar graphs, trend graphs, and voltage & current waveforms.
Multiple units
  • WTViewerFreePlus can connect up to four WT300 / WT300E series units (with same model code).
  • The WT300 / WT300E series provides flexibility by offering various communication interfaces such as USB, Ethernet, GPIB and RS-232.
  • With the Device Search feature, the software allows automatic PC connection.
  • The software allows instrument configuration and measurement of up to 200 measurements simultaneously.
Software Menus
Connection: Communication configuration between WT and PC
Setting: Set up WT measurement parameters
Measure: Display measured results in bar graphs, trend graphs, etc.
File: Save and load setup parameters
Exit: Exit the software
Types of Display Screens The following types of display screens are available.
  • Numeric Displays WT's measurement data numerically. For models with the harmonic measurement option (/G5), harmonic measurement data is also displayed.
  • Numeric List Lists harmonic measurement data for each harmonic order. Numeric lists can be displayed when the WT is equipped with the harmonic measurement option (/G5).
  • Numeric Matrix Displays WT's measurement data for each element.
  • Waveform Displays waveform display data that has been collected from the WT. Waveforms can be displayed when the WT is equipped with the harmonic measurement option (/G5).
  • Trend Displays changes in measured data over time on a trend graph.
  • Bar Graph Displays measured harmonic components for each harmonic order. Bar graphs can be displayed when the WT is equipped with the harmonic measurement option (/G5).

Data Acquisition Interval 100 ms at max. speed. - The data storage period can be any custom settings (more than 2 seconds) and the data update rate of the body. - Depends on your PC's performance.*When the WT data update interval is shorter than the time it takes for the software to collect one set of measured data, there will be pieces of data that the software will not collect.
