Data Conversion Methods
Temperature Conversion:
- 0~2V DC: T = 50*V - 30
- 0~5V DC: T = 20*V - 30
- 0~10V DC: T = 10*V - 30
- 4~20mA: T = 6.25*A - 55
Humidity Conversion:
- 0~2V DC: H = 50*V
- 0~5V DC: H = 20*V
- 0~10V DC: H = 10*V
- 4~20mA: H = 6.25*A - 25

Usage Precautions
- Check packaging for integrity and verify product model and specifications upon receipt.
- Install away from corrosive chemical environments.
- Keep sensors and wires away from high voltage and heat sources.
- Store sensors in a dry, ventilated, and normal temperature indoor environment as they are precision instruments.
- Do not disassemble the sensor yourself to avoid damage.
