Report of Test on Underwater Electric Log Equipment, Contract NOs-71894 Submitted by Bendix Aviation Corporation Marine Division
Abstract
The subject log equipment was set up at this Laboratory in conjunction with suitable test apparatus and its performance was carefully observed for compliance with the specification. Flowing calibration by the manufacturing's representative, an initial accuracy test was made. Tests were then made to determine the effect of inclination, variation in supply voltage and frequency, endurance, shock, vibration and hydrostatic pressures. Additional accuracy tests were made on several occasions to isolate the errors resulting from the several test conditions. Observations were made in a dark room to determine the quality of the dial illumination. The test was concluded with a brief check against the drawings and an inspection of the equipment to determine compliance with those requirements of the specification on which pertain to materials, design, and workmanship.
