NIKON - nikon F Photomic FTN service
by NIKONComprehensive technical documentation dedicated to the maintenance and repair of the Nikon FTn light meter. This detailed guide covers the electrical operation of the light measurement system, including an annotated electrical schematic showing circuit configuration in both test and meter modes. The document explains the role of CdS photocells, adjustment potentiometers, and critical electrical components. The troubleshooting section identifies common failures: weak batteries, poor electrical contacts, main potentiometer defects, and sensitivity issues. Each symptom is correlated with probable causes and recommended solutions. For adjustment, the guide provides step-by-step procedures using an 18% gray card and measurement against calibrated light sources. Instructions cover sensitivity adjustment and meter test calibration. The disassembly section furnishes precise steps for accessing internal components: cover removal, trimmer pot access, cable disconnection, and case separation. Cleaning instructions recommend gentle solutions and lint-free swabs, with warnings against spray cleaners. Annotated photographs illustrate screw locations, contact points, and critical assemblies throughout the procedure.
