Abstract : The purpose of the Space Technical Data Report (STDR) is to familiarize personnel with the operation and service instructions for the Helium Leak Detector Cabinet, 52E420097-1 and 52E420097-101. The two configurations are functionally the same with the 52E420097-101 assembly incorporating a modified leak detector with ultra high sensing capabilities for hydrogen leak detection. The information contained in this document pertains to both detectors; however, only the Helium Leak Detector will be mentioned. Addendum A contains information pertaining to the Hydrogen Leak Detector, which differs from that of the Helium Leak Detector. The STDR presents a description of the detector, its control and indicator functions, and service instructions for preventive maintenance. (Author)
