Description
Overview
The Fluke 752A Reference Divider sets the standard for ratio accuracy and ease of use. It offers two divider outputs with 10:1 and 100:1 ratios and output uncertainties of less than 0.2 ppm and 0.5 ppm respectively. The device features a built-in calibration bridge with dynamic resistor matching, allowing self-calibration with only a stable voltage source and a null detector in approximately five minutes without requiring external standards.
