The dataT aker DT80 Series 3 manual describes its rugged, low‑power data acquisition features, interfaces, software dEX and technical specifications.
The DT80 Series 3 is a compact, stand‑alone data logger with 18‑bit resolution, USB‑drive support and an integrated display. It offers up to 10 isolated or 15 shared analog inputs, SDI‑12 sensor networking, and communication via Modbus, FTP and a web interface for SCADA integration. The built‑in dEX software runs in a web browser, providing real‑time monitoring, configuration, and data export to CSV or DBD formats.
The manual covers hardware specifications such as analog channel isolation (100 V), storage capacity (128 M, ~10 million points), sampling speeds up to 25 Hz, and power options including a 12 V DC supply and internal 6 V battery. It also details communication ports (Ethernet, USB, RS‑232), digital I/O, counter channels, and firmware upgrade procedures. This manual is written in Chinese.
