Abstract :
The equations for the capacitive error of various constructions of audio-frequency current comparators are derived and discussed. The experimental procedure for trimming a comparator using an excitation winding is presented. The interrelationship between sensitivity and accuracy is indicated. An approximate diagram showing the size and error as a function of rated current for a matched sensitivity-error design is given.
