Features
Measurement
The RD-3X Analyzing Standard registers both forward and reverse energy flow and provides voltage, current, power and energy (Active, Reactive, Apparent) information.
Meter and Standard Testing
The RD-3X Analyzing Standard is the ultimate instrument for on-site accuracy testing of electricity meters, performing power quality analysis, testing current transformers (CT), and site wiring confirmation. The Analyzing Standard is designed to work with customer load or a stand-alone current source.
Overview
The Radian Three-Phase Analyzing Standard is packaged in a robust case and features the performance of the Radian Research RD-3X family of reference standards. The Analyzing Standard provides unsurpassed accuracy, functionality, and ease of operation.
Radian’s Analyzing Standard is so versatile that the functionality is like having three instruments in one. The standard is the ultimate instrument for on-site accuracy testing of electricity meters, performing power quality analysis, testing current transformers (CT), and site wiring confirmation. The Analyzing Standard is designed to work with customer load or a stand-alone current source.
Highlights

RD-3X Analyzing Standard Measurement & Functionality Configurations
The second digit of the first two digits and the last three digits determine the full RD-3X model number. The second digit of the first two digits designates the accuracy class. The first digit of the last three digits determines the measurement functions; the second digit of the last three digits determines if the instrument has a built-in computer with touch screen display, power analysis, and analog sense capability; the third of the last three digits determines the current input configuration.
