Page 5: Introduction
Due to the integration of the basic node other sensors – like a wind sensor - can be interfaced and the signals will be combined in 1 NMEA stream. This manual is intended for the System integrator, Installer and Commissioner of the Observator OIC-406 temperature and humidity sensor. -
Page 6: Safety
2 Safety For correct functioning of Observator OIC-406 it must be installed according installation instructions. Any unused gland should be filled with the include plug when not in use. The OIC-406 probe is a sensitive instrument, store dry. Direct contact with salt water can make the probe unusable for humidity measurement! Remember: instruments are tools. -
Page 7: Description
3 Description 3.1 General description Observator Meteolink OIC-406 uses an accurate combined temperature and humidity probe.. The vented anti-radiation shield has been designed to create a natural airflow which contributes to the accuracy of the sensor. The probe signal is converted into a standard NMEA signal by the basic node, which also functions as a junction connection box. -
Page 8: Installation
The sensor will start heating first (for humidity measurement) and will not produce data until the first cycle is finished. It can take up to 6 minutes before the OIC-406 produces data at start up or after a power cycle. OIC-406 Manual... -
