PC connectivity for control, data collection and analysis

05 June 2017

Yokogawa’s new WTViewerE software provides PC connectivity for the company’s power analysers via Ethernet, USB, GPIB or RS232 interfaces. This allows users to more easily control, monitor, collect and analyse measurement data, and save measurements remotely.

WTViewerE enables synchronised measurement of up to four WT units. The software automatically detects connected units and displays a list. Users are then able to view and change measurement conditions such as wiring system, voltage and current range, update interval, synchronisation source and display format.

The software supports split-screen displays for multichannel power measurements, allowing users to customise analysis procedures. The systen can simultaneously display up to 12 waveforms, eight trends, eight vectors and six harmonic bar graphs. Users can also save and load screen layouts. 

Cursors can also be used to zoom in on specific areas of interest to show more detail on numerical, harmonic and waveform information, as well as specifying the necessary data to be saved in CSV format. 

In the online mode, users have real-time control of measurements from each connected unit. Users can start or stop integration and remotely monitor and collect live measurement values. In offline mode users can analyse the latest acquired or previously stored data.
