1. Keep the instrument always clean and store up properly
2. The liquid of air pressure meter should maintain a specific height
3. Clean the cylinder and perforated plate after test and storage properly
4. Check the Electromagnetic pump before testing, the negative pressure should be adjusted in advance, avoid to suck into the pump;
5. During the test if found the liquid level can’t rise to the top scale mark, or the liquid level was rise too fast (rise to glass tube ball pump and valve still not stop). Under this condition can press “Enter” to stop test immediately, and can open the back cover to adjust the Throttle to adjust the negative pressure changing rate.
6. Do not use the instrument under intensive sunlight condition or frequently changed light brightness occasion.
