2、 Precautions
1. It should be used in an environment within the indicated range. Do not come into contact with steam and do not blow air with your mouth to avoid condensation on sensitive components, which may cause drift in readings.
The usage environment should be clean and dust-free, and should not be used in environments with severe pollution such as corrosion and volatile gases.
3. Place in a naturally ventilated area, away from cold and heat sources, to avoid sudden cooling and heating; The reading can only be taken when the temperature and humidity of the surrounding environment are balanced.
4. Avoid severe vibrations and impacts on the instruments; Do not disassemble or adjust by yourself.
The temperature and humidity meter should be regularly checked and calibrated by professionals. The testing method should follow the company's standard, and the humidity should be tested point by point from low to high at the specified temperature.
Instruments should be hung or placed vertically.
