Overview




WECO’s next generation Meter Site Analyzer delivers three-phase field-testing utilizing the Radian Research RD-3X series reference standard integrated within the unit. The RW-3X NS allows you to execute a multitude of tests at the customer’s site. Testing the meter with the customer’s load, performing CT burden and ratio tests, and verifying system wiring gives you the peace of mind that the entire metering installation is correct. The RW-3X NS series also provides for Harmonic Analysis, CT Testing, Vectors, and Trends Testing all without ever pulling the meter from its socket.

Using the RW-3X NS is a familiar process due to the Microsoft™ Windows® 7, 64-bit operating system embedded within the unit. Large internal storage allows for numerous test results, as well as custom site configuration and test sequences to be saved locally on the RW-3X NS. The convenient touch screen interface allows instant access to the Winboard Embedded application without the need for an external keyboard, mouse, or monitor. These, however, can be easily connected to the RW-3X NS, providing you with additional options. You can also control the RW-3X NS from your iPhone or iPad by using WECO’s Winboard Embedded Remote App — available for free in the iTunes App Store. A durable screen protector supplies an extra safeguard for the 8.4” LCD touch screen while shielding against glare for better visiblity.
