The Light Duty Utility Arm (LDUA) is a remotely operated manipulator used to enter into underground waste tanks through one of the tank risers. National Electric Code requirements mandate that the in-tank portions of the LDUA be maintained at a positive pressure for entrance into a flammable atmosphere. The LDUA Purge Air Supply System (PASS) is a small, portable air compressor, which provides a constant low flow of instrument grade air for this purpose. This procedure is used to assure that the instrumentation and equipment comprising the PASS is properly adjusted in order to achieve its intended functions successfully
