The WTViewerEfree is free software for power analyzer models that include WT series*. The software simplifies instrument configuration and gathering of measurements.
*WT5000/ WT3000E/ WT3000/ WT1800E/ WT1800/ WT500/ WT300E/ WT300
You can use the software to connect the WT series to a PC for access to the following:
You can use this software to control a single PC-connected WT series.
As well as using the WT series front panel to set up the power analyzer, users can apply the software to quickly set up desired settings. It also shows all the settings and the status at a glance.
The software can display items that cannot be shown on a screen of the WT series, such as multiple numeric measurement parameters, harmonics data of each other, bar graphs, trend graphs, vector, and voltage & current waveforms together.
The software has the following menus:
Displays WT series measurement data numerically. For models with the Harmonic measurement option (/G5, /G6) or the Advanced Calculation option (/G6), harmonic measurement data is also displayed.
Lists harmonic measurement data for each harmonic order. Numeric lists can be displayed when the WT series is equipped with the Harmonic measurement option (/G5, /G6) or the Advanced Calculation option (/G6).
Displays WT series measurement data for each element.
Displays waveform display data that has been collected from the WT series.
Displays changes in measured data over time on a trend graph.
Displays measured harmonic components for each harmonic order. Bar graphs can be displayed when the WT series is equipped with the Harmonic measurement option (/G5, /G6) or the Advanced Calculation option (/G6).
Display harmonic measurement parameters (fundamental components) as a vector plot. Vector plots can be displayed when the WT series includes the Harmonic measurement option (/G5, /G6) or the Advanced Calculation option (/G6) and more than 2 sets of the same input elements.
Measuring Mode | Normal, harmonics, integration |
Types of Files | Waveform, calculated values, harmonics, settings |
Display Screens | Numerical, waveform, trend, harmonic bar graph* and vector plot* * The Harmonic measurement option is required. |
Data Acquisition Interval | 50 ms at maximum speed. - The data storage period can be any custom setting (more than 20 seconds) and the data update rate of the product. - Depends on your PC's performance.* When the WT series 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. |

Designing an instrumentation system for high current measurement requires careful consideration of the trade-offs associated with each type of sensing device. The purpose of this application note is to help engineers understand the sensing choices available and the corresponding trade-offs with each technology.
