The Sencore CM2125 calibration procedure manual provides detailed instructions for setting up, operating, and troubleshooting the device, including steps for warming up the unit, checking video patterns, and performing various calibrations using equipment like the Fluke 5101 Calibrator and DVM. It covers specific adjustments for video levels, drive signal levels, and drive board calibration, ensuring all readings are within specified tolerances and that all signals are present and not distorted.
Manual Overview
The Sencore CM2125 calibration procedure involves several steps to ensure accurate performance of the VGA/SVGA monitor. Initially, the unit must be warmed up for 20 minutes, verifying the 300V LED flashes and the display reads 18.4 kHz. The fan operation is checked, and video patterns are confirmed to be present and undistorted. For battery checks, the Fluke 5101 calibrator and Fluke 8842A DVM multimeter are used to ensure the DVM reads less than 6nA. Calibration of the digital display involves adjusting resistors R42 and R39 for precise voltage readings. Video levels are calibrated by adjusting resistors R45, R46, and R47 for specific voltage outputs. Drive signal levels are adjusted using the SC61 oscilloscope to ensure correct voltage peak-to-peak readings. The drive board calibration involves setting the drive level and adjusting R55 and R56 for accurate DC voltage. The procedure ensures the CM2125 operates within specified tolerances, with adjustments made at the board level for precise functionality.
