Nearly four decades ago Radian Research revolutionized the portable electric energy reference standard market with the RM-10 Metronic Portable Watthour Standard. Word spread quickly and soon there were stories about the incredible measurement accuracy and precision coming from this magical little blue box. A Legend was born. Exceptional performance combined with the iconic cube shape led to the RM standard often being referred to simply as a RADIAN. In electric meter shops and labs around the world, RADIAN is synonymous with STANDARD.
Radian Research is the Leader in assuring the Integrity of AC electric energy measurement. RADIAN Power and Energy Reference Standards are Respected worldwide for their Legendary accuracy, precision and stability. Xytronic technology utilizes high performance analog to digital converters coupled with RADIAN’s renowned signal sensing technology, hermetically sealed references and enhanced calculation algorithms to set a new standard for power and energy measurement. RADIAN RX standards are available in 0.04%, 0.02% and 0.01% models, the RX-10, RX-11 and RX-15. These guaranteed accuracies include the variables of stability, traceability uncertainty and test system errors. RADIAN’s ISO 17025, A2LA accredited laboratory maintains direct traceability to the National Institute of Standards and Technology (NIST) and the National Research Council (NRC) for AC energy. NIST and NRC traceability is recognized and respected by other National Metrology Institutes around the world.
The RX-10, RX-11 and RX-15 are four-quadrant, single-phase instruments that provide simultaneous measurement of voltage, current, phase angle, power and energy (active, reactive and apparent). All metrics are available as traditional Wideband or Fundamental, where the latter filters out any harmonic content from the input signals. Delivered and Received energy metrics are reported independently. Support for six different Reactive (VAR) calculation methods along with the addition of Vector VA metrics further distinguishes the RX standard. The RX-10, RX-11 and RX-15 compute and present over 40 reference caliber metrics concurrently. Power Quality metrics include Harmonics and THD for voltage and current. This vast metric set makes the RX standard one of the most powerful measurement engines ever.
The unique design and flexibility of the RX-10, RX-11 and RX-15 make them conducive for numerous electric metering applications. At a meter site, use it with a controlled current source to test revenue billing meters. In the meter shop, as a secondary standard to certify the accuracy of meter test boards. In the meter lab, calibrate reference standards of lesser accuracy, a linchpin in the chain of standardization for energy measurement. The 0.01% accuracy RX-15 is suitable to serve as a company master standard. In meter engineering, as an invaluable tool for evaluation, analysis and design of any power or energy related instrument or system. Whatever your application, the RX-10, RX-11 and RX-15 will meet your needs.
The RX-10, RX-11 and RX-15 operate over a broad measurement and temperature range making it one of the most versatile reference standards available. Autoranging voltage inputs of 60-600 VAC and currents of 20 mA to 225 A provide flexibility to operate in a large variety of power and energy applications. The RX standard’s ability to maintain exceptional accuracy at temperature extremes makes it suitable for virtually any measurement environment.
Familiar User Interface
The RX-10, RX-11 and RX-15 utilize a five-button keypad with a backlit LCD as its direct user interface to easily view metrics and setup device parameters. RADIAN duplicated the highly popular interface of the RD-2x series to further ensure a smooth transition to the RX platform. Use the Built in Comparator to test a meter or other reference standard and the test results will be automatically calculated.
Revitalize Vintage Equipment
The RX-10, RX-11 and RX-15 were specifically designed and are ideally suited for upgrading existing test equipment. It’s CLASSIC cube shape and traditional connection scheme enable simple retrofit of field test sets and meter shop test boards. Bring your vintage test equipment to life with a new RADIAN RX-10, RX-11 and RX-15 Xytronic measurement engine.
Enhanced Control and Communication
The RX-10, RX-11 and RX-15 provide superior control and communication over that of the RD platform. Standard Command Programming Interface (SCPI) is used to communicate to the RX-10, RX-11 and RX-15. It is fast and provides easy connectivity using standard protocols. SCPI is based on industry standards, is easy to program and provides comprehensive access to all RX functionality. SCPI allows time-synchronous measurements of harmonics, metrics and waveforms across all phases/axes. Ethernet is used for programmatic control of the RX using SCPI as well as for software updates.
Legacy Software Support
The RX-10, RX-11 and RX-15 provide backwards compatibility with software that was developed for the RD platform. This includes support for PC-Suite version 5.0. PC-Suite is a simple but powerful tool to provide access to tools including Metrics, Harmonics, Waveforms, Meter Test, Standard Test, Trending and Automation. The RX-10, RX-11 and RX-15 support the legacy serial communications commands from the RD series standards. In general, almost any program written to control an RD will work with an RX-10, RX-11 or RX-15.
