Vaisala HMD60 Operating Instructions
The HMD60U/Y humidity‑temperature converter is a loop‑type sensor that can be mounted on ductwork without removing the circuit board. Installation is done by attaching a template to the duct surface, drilling the indicated holes and securing the unit with screws. The signal cable connects to a 5‑pin screw‑type terminal and must be grounded using the provided brass bushing.
Calibration is performed with a Vaisala HIMT41 instrument and the optional calibration cable. The manual also describes sensor‑head removal and replacement, spare‑part numbers, and provides technical data such as measurement range, supply voltage, and operating temperature limits. This manual is written in Japanese.
