Tips: Precautions For Explosion-proof Temperature and Humidity Sensor Use

To turn the screw on the top cover, press the screw with a screwdriver and then turn the screw.
When connecting terminals, do not strip the cables too long, and do not expose the copper wires directly inside the product to avoid short-circuit risks.
Disconnect the power supply before connecting the circuit.
Do not touch internal components directly with hands or metal objects.
After the installation is complete, check the screws on the cover and whether the waterproof connector is locked. The wire diameter must be 4-8mm.
5 minutes after switching on the power supply, the calibration operation will be carried out. Otherwise, the data output will not be accurate.
