Features

RX Screens

Light Weight, Compact... Metrology capability
in Power and Energy Measurement that is
surpassed by none!



Designed for CE & UL Safety Compliance Operator safety is always a concern of our customers. RX is designed to meet the requirements defined in recognized CE and UL product safety standards. RX users can be assured that when designing the RX, user safety was a top concern and has been enhanced with this new reference standard.


Extraordinarily Versatile Uncompromised power and energy performance over a broad measurement range in a single rugged solution. Whether integrated within a field test box, stationary test rack or used as an engineering lab tool, the RX is extraordinarily versatile. Whatever your requirement RX can fill your need.


Expanded 17025 Lab Accreditation Customer Service & Support brand loyalty is built on trust developed over the past 35 years of uncompromised product design and manufacturing. Customers world-wide have proven this performance for themselves. Those considering Radian products for the first time can gain assurance from our industry leading measurement uncertainties backed by A2LA, an independent 17025 accreditation assessment agency. See latest scope of lab accreditations at www.radianresearch.com/cert.php.


Maximize Signal Processing The RX uses the latest Digital Signal Processing (DSP) technology incorporating nine high speed 1,000,000 samples/second A/D converters. In addition, the flexibility of frequency domain processing algorithms optimizes measurements for the specific signal parameters of interest.






Overview



PRODUCT HIGHLIGHTS

Radian Research is committed to providing our customers with leading innovative and technologically superior products, while maintaining metrology capability in power and energy measurement that is surpassed by none. Our engineers drew on the expertise and knowledge we acquired for our industry-leading legacy RM (Metronic) and RD (Dytronic) reference standards to develop the RX (Xytronic), the ultimate in power and energy measurement technology perfection.


Extended Measurement Range The RX is designed to operate over a broad Current, Voltage and Power Factor measurement range. A dynamic range of 30 VAC - 600 VAC and 5 mA – 200 A provides the versatility to operate in a multitude of power and energy applications. The AC direct current input provides fixed impedance (0.0005 Ohm) over the entire AC current input range. This capability is key to applications that require a fixed input burden and accurate yet fast measurement speed. The RX provides three-phase fully auto-ranging, simultaneous four-quadrant precision measurements, computes, records and presents instantaneous metrics. The RX allows the user to do more with a single instrument.


Internationalization The RX is designed for a global market where user languages may vary. The RX accommodates different languages as well as selectable VAR calculations and a broad range of energy measurement metrics including fundamental only Watts, VA and VAR. RX VAR calculation modes include Voltage 90 degree shifted, Integral VAR, Integral VAR 50 Hz, Integral VAR 60 Hz, RMS VAR, and Fundamental VAR.


Accurate in Extreme Environments Most Power and Energy reference standards are designed to maintain accuracies in a temperature controlled laboratory environment. Not the RX, it is at home in a temperature controlled measurement lab and at a test site where the environment is outside the operator’s control. Radian’s confidence in the RX design is supported by the guarantee that it will meet class accuracy at specified temperature extremes. You can test with confidence when using the RX.
