| Section | Content | |--------|---------| | | Lamp heat hazards, high voltage in power supply | | Theory of Operation | Optical path (lamp → filter → lens → plate well → photodiode → ADC) | | Disassembly | Step-by-step removal of cover, filter wheel, lamp housing, mainboard | | Electrical Schematics | Analog front end, motor drivers, power regulation, microcontroller I/O | | Calibration Procedure | Using certified neutral density filters, adjusting gain, setting blank reference | | Diagnostic Mode | Hidden menu access (often key sequence on touchscreen) | | Error Codes | e.g., ERR 03 = Filter wheel timeout, ERR 07 = Lamp low intensity | | Parts List | Lamp type (6V 10W halogen), photodiode (e.g., S1223), stepper motor model | | Firmware Update | If applicable — using RS-232 and a PC with XMODEM protocol | | Wiring Diagrams | Ribbon cable pinouts, sensor connectors (home position, door interlock) |
