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:
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.
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.
|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|
The following types of display screens are available.
|Measuring Mode||Normal, harmonics, integration|
|Types of Files||Waveform, calculated values, harmonics, settings|
|Display Screens||Numerical, waveform*, trend, harmonic Bar Graph*
* /G5option is required on .
|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.
