Extract

An instrument is described which measures the time duration of a specified number of complete cycles of an oscillation over the frequency range OT cycles per second to 500 cycles per second. The accuracy of the reading is dependent on the frequency measured and the number of cycles taken; but, in most cases, an accuracy better than 01 per cent is obtainable. The construction of the instrument is described and circuit diagrams given.
