1-6 series wide temperature type temperature and humidity transmitter user manual, detailed introduction of product uses, technical parameters, appearance, wiring, installation and use methods, etc.
The WSDL-6 series is a wide‑temperature humidity transmitter that measures temperature from –40 °C to 120 °C and relative humidity from 0 % to 100 % RH. It features a sealed waterproof design, a 2‑line LCD display, and both current (4‑20 mA) and voltage output options.
The manual covers installation methods (wall‑mount, pipe‑mount, and split‑type), wiring colour codes, operation steps, safety precautions, routine maintenance, storage guidelines, and troubleshooting procedures. It also provides technical specifications and calibration recommendations. This manual is written in Chinese.
