Abstract
A ratio meter and apparatus for measuring electrical components with high stability and no effect on the circuit under test. Two input signals are switched by a switching means and the inputs to two measuring means are measured while keeping the switches in a first state and a second state to find the ratio of the measurements. The ratio to be measured, which is related to the above-mentioned input signals, and which forms a bilinear equation with the two ratios, one each obtained under the first and second state, are obtained from said ratios. Accurate calibration is performed and measurement of electrical and electronic components with high stability is accomplished by connecting a front-end circuit with the ratio meter.
