Manual Overview

The Hammarlund SHEETS manual provides detailed instructions for troubleshooting, calibration, and adjustment of the device. It emphasizes the importance of connecting the signal generator to the grid cap of the first detector and grounding the output cable shield to the chassis for accurate diagnostics. The manual outlines a step-by-step process for adjusting various capacitors and inductors to achieve maximum amplitude and proper alignment. Technicians are advised to use the crystal selectivity switch and phasing control to obtain identical images on the oscilloscope, ensuring the phasing control setting aligns with the arrow indicator. Calibration involves setting the frequency control of the signal generator to match the crystal frequency, followed by adjustments to the IF stages for maximum amplitude. The manual also covers board-level guidance, including checking the alignment of the shaft and pointer, and ensuring rotor plates are correctly meshed. For calibration, specific crystal frequencies are used for different bands, with intermediate check points provided for accuracy. The manual stresses the importance of maintaining proper settings and alignment throughout the calibration process.
