IV Notices
1, because the relationship between the environment relative humidity and temperature more closely, therefore, the point is to measure the ambient humidity sensor and the environment to maintain the same temperature.
2, installed in the environment is relatively stable area, avoid direct sunlight, away from windows, air-conditioning and heating equipment, to avoid the straight on the window or the door.
3, install or remove the transmitter, it must first cut off the power, and then install or remove.
4, try to stay away from high-power jamming equipment, so as to avoid inaccurate measurements, such as the inverter, motor and so on.
5, please read this manual carefully before using to ensure the wiring is correct, any wiring errors are likely to cause irreversible damage to the transmitter.
6, to prevent chemical reagents, oil, dust and other directly against the sensor, not in condensation, long-term use under extreme temperature conditions. Do not thermal shock.
