Test of Annunciator Equipment and Buzzer. Chas. Cory Corporation Exhibitor; Repair of Model OA Antenna Measuring Equipment Type 4360, Serial #1
Abstract
Abstract 1: The subject material was set up at this Laboratory and connected in circuits simulating service conditions and closely observed in order to ascertain its performance and ruggedness while under test for endurance, over and under voltage and frequency, and shock integrity. The usual test for temperature rise of the windings, insulation resistance and dielectric strength, then followed. Abstract 2: The Set #1PH was repaired mechanically and electrically and tested for accuracy of measurements of capacity and resistance. A number of mechanical defects were found and repaired. Serial #1PH was compared to Set #6NRL and both were tested using certain external loading coils as well as the internal loading coils mounted in the sets.
