Operates electronically controlled sound reproducing and photographic equipment (section plotter) to record seismic waves from magnetic tape recordings of explosions reflected or refracted from subsurface strata: Starts equipment and moves controls to align adjacent recordings uniformly on positive photographic film, following tracings of wave form shown on indicator. Verifies identification data on magnetic tape container to ensure specified order of sound reproduction. Clamps magnetic tape around drum of sound reproducer, starts machine, and observes wave form on oscillograph to detect malfunctions. May develop and print photographic recordings in darkroom. May test circuits, resistors, transistors, and related equipment parts, using schematic drawings, wiring diagrams, and electronic test equipment. May replace defective parts and repair faulty connections, using soldering iron.
