Abstract :
A measuring system has been developed which will automatically measure and record in numerals at predetermined intervals items which can be measured electrically. The readings may be telemetered over a single channel for any distance. The paper describes briefly, with the aid of block diagrams, the process by which the instrument measures, telemeters, and prints the readings on a ``log sheet.´´
