<p>Two oscillators are driven at nearly the same frequency, where the oscillating frequency of one oscillator is determined by the given circuit and that of the other has suitable controls for synchronisation with the first oscillator. The phase difference between the oscillators is taken as a measure of the property to be considered. The equipment also contains means for defining the sizes of electrical parts to handle the energy requirements. The object of this device is to improve the accuracy of the various components for oscillators. An indicator and an output relay are used to achieve output of results.</p> |
