The Fluke 6105A and 6100B electrical power standards enhance measurement accuracy and flexibility in increasingly complex power systems, addressing challenges such as harmonic distortion and voltage fluctuations. These devices are designed for various applications including validation, calibration, and testing of energy measurement instruments, providing traceable and precise measurements across multiple phases. The 6105A offers superior accuracy for secondary standard calibration, while both models cater to the demands of smart metering and power quality testing standards.
