YD-K7 is an expansion accessory specifically for the Konica Minolta CL-700A spectral illuminance meter. It adds a high-definition display,independent measurement components and interfaces; it serves as an external display with synchronized data and enables flexible optical measurement in laboratories,field work and complex settings. A3.5-inch screen shows live spectra/data lists,with data hiding and drag sorting. Single/continuous measurements update in real time. SD-card management saves,browses and recalls files. Settings include Chinese/English/Japanese,brightness,automatic saving,wavelength ranges,calibration-channel recall,speed and themes. Type-C,wireless communication and expandable control improve operation. Instructions:hold power about3 seconds to start or shut down. Connect YD-K7 to CL-700A with Type-C; the interface shows device name/SN. Tap Measure or press the hardware key for one measurement and updated spectra/data. Continuous mode collects until Stop. With an SD card,file management browses data,selects save paths and renames files. Brightness uses a slider; autosave follows measurement time. Select360–860nm or360–1050nm ranges,recall user calibration channels,and choose normal/fast/ultrafast measurement or light/dark themes.
