There are different reasons for performing a round-robin test: determination the reproducibility of a test method or process; verification of a new method of analysis. If a new method of analysis has been developed, a round-robin test involving proven methods would verify whether the new method produces results that agree with the established method.
A residual-current device (RCD), residual-current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) [a] is an electrical safety device, more specifically a form of Earth-leakage circuit breaker, that interrupts an electrical circuit when the current passing through line and neutral conductors of a circuit is not equal (the term residual relating to the imbalance), therefore ...
Robin guitars were made in Japan by Tokai and Chushin until 1986, when their production moved to the United States. [2] Notable endorsers include Stevie Ray Vaughan and his brother Jimmie , who were frequently seen onstage with the "RDN" 6-string standard neck/6 string octave neck double-neck guitar in the 1980s.
RRDtool (round-robin database tool) aims to handle time series data such as network bandwidth, temperatures or CPU load. The data is stored in a circular buffer based database, thus the system storage footprint remains constant over time. It also includes tools to extract round-robin data in a graphical format, for which it was originally intended.
Entry-level cable testers are essentially continuity testers. A continuity tester is an item of electrical test equipment used to determine if an electrical path can be established between two points; [1] that is if an electrical circuit can be made. The circuit under test is completely de-energized prior to connecting the apparatus. [1]
