This manual covers the AT808 series intelligent digital regulator, describing its features, model definitions, installation steps, and electrical connections. Detailed sections explain panel layout, display functions, key operation, software configuration, PID parameter tuning, fault indications, and linear input calibration.
Additional chapters address curve‑program control, serial communication interfaces, optional functions such as printing and analog set‑point transmission, and technical data including measurement ranges, accuracy, power supply, and environmental specifications. This manual is written in Chinese.
