WTVIEWER APPLICATION SOFTWARE (760122)
WTViewer acquires numeric, waveform, and harmonic data from the WT3000/WT1800/WT500/WT1600/WT210/WT230* Digital Power Analyzer via Ethernet, GP-IB or serial communications (RS-232) and USB. Data can be transferred into your personal computer via those communication interfaces. It lets you view waveforms on your computer, convert numeric or waveform data to a specified format, and store the data.
*Digital Power Analyzers WT1600/WT210/WT230 are discontinued products.

Ethernet Functions*Requires the WT3000/WT1800/WT500/WT1600's optional Ethernet function to utilize this function
FTP Server/FTP Client
WTViewer can simultaneously control up to four WT500s, four WT1800s, four WT1600s or four WT3000s for multi-channel measurement.
|The FTP client function makes it possible to transfer data saved in the WT3000/WT1800/WT500/WT1600 internal memory to your PC.|
PC Direct Connection
[GP-IB/serial (RS-232)/Ethernet, and USB]
* Ethernet connection requires two straight cables and a HUB.

Screen DetailsNumeric Data
|You can display the data measured with the WT3000/WT1800/WT500/WT1600/WT210/WT230 on your PC via Ethernet/GP-IB/RS-232 communication and USB. WTViewer can also simultaneously show various parameters for one to six elements and for Sigma-A to Sigma-C(related writing setting) calculations, for simple channel-by-channel data comparison.|
||You can capture various types of data measured with the WT3000/WT1800/WT500/WT1600/WT210/WT230 in your PC at fixed intervals. Thus, you can view trends graphically. This feature lets you monitor power supply voltage fluctuations, changes in current consumption and other time-based variations.|
|In harmonic measurement, you can see harmonic data with bar chart. It shows three items at same time.|
|In harmonic measurement, you can have a vectorial view of the fundamental voltage, current and phase angle. This visual presentation of the interphase relationship in a three-phase power system shows the load condition intuitively.|
Setting Up the WT Power Analyzer from a PC
|With WTViewer, you can control the WT3000/WT1800/WT500/WT1600/WT210/WT230 main unit from your PC, including setting the wiring method, range, filter, and scaling, and so on. WTViewer also lets you save or read the settings of the Power Analyzer onto your PC.|
Converting Data to CSV Format
|With WTViewer, you can save waveform and numeric data to your PC, while on the PC you can create *.wtd files that can be loaded in WTViewer, or *.csv files that can be imported into Excel spreadsheets. WTViewer also lets you save screen images of measured numeric and waveform data.
WT3000/WT1800: Computation with Data from Multiple Units
|Enables acquisition of data from multiple units
WTViewer can acquire data from up to four units simultaneously. Plus, it now includes accurate computation functions that can perform addition, subtraction, and efficiency computation of data from multiple powermeters. For example, three-phase power from the first unit (A) and three-phase power from the second unit (B) can be measured on WTViewer and subsequently used in up to 15 different user-defined expressions such as A+B, or B/A*100 (efficiency).
Note: Requires that the WTs be of the same model and option code. Not supported if the WT3000 and WT1800 are combined.
Viewer Software for Data Acquired Offline
|Until now, measured data acquired offline and saved to the WT's memory media could be loaded and displayed on a PC, but required running a file reader program that was separate from WTViewer. With the new version upgrade, the file reader program has now been conveniently integrated with WTViewer.
* Even after the 30-day trial period of the demo version, users can continue to use the "Off-Line + File Loading with WTFileReader" function.
