User manual for the ZDF-5210P series composite vacuum gauge, covering operation, specifications, connections and communication settings.
The ZDF-5210P series composite vacuum gauge combines a resistance unit and a hot‑cathode ionization unit to measure vacuum from high vacuum to atmospheric pressure. The manual provides detailed instructions on installation, front‑panel operation, button functions, and safety precautions.
It also describes the various model configurations (‑2 and ‑3), wiring of output terminals, relay and analog signals, and the serial communication options (RS‑232/RS‑485 with Modbus‑RTU). Calibration procedures for both resistance and ionization units are included. This manual is written in Chinese.
