Calibration of precision measuring amplifiers for strain gauge transducers

A method is described that utilizes a ratio device consisting of multi-decade inductive voltage dividers to calibrate precision measuring amplifiers for strain gauge transducers. Most frequently, this device is used to calibrate 2.5 mV/V ranges of the amplifiers, relative standard uncertainty being 5 ppm for the ratio of 0.0025 and at 225 Hz.
