1. There should be no oily and corrosive substances and other impurities in the standard instrument and the instrument to be tested, otherwise it will affect the normal operation of the instrument.
2. When removing the pressure gauge, the system must be in zero pressure.
3. When converting vacuum or pressure, the system must be in zero pressure.
Common faults and treatment methods
1, can not hit the pressure, the hand pressure pump has the feeling of air pressure
Reasons: 1) The reversing valve is not in the position of commutation, resulting in air leakage.
2) There is no reset after the positive pressure check valve or the negative pressure check valve moves, resulting in air pressure.
Treatment: The reversing valve must be reversing in place.
2, the pressure pump can not be pressed
Treatment method: Check the seal inside the pressure regulating pump for damage.
3, no pressure or no pressure output on one side
Solution: Check if the output port is blocked.
4, negative pressure does not meet the standard
Treatment method: It should be judged whether the instrument is normal according to the actual local atmospheric pressure.
Infrared range finder refers to laser infrared range finder, which is a kind of laser range finder. Infrared rangefinder is an instrument for precision ranging with modulated infrared light. The measuring distance is generally within 150 meters, and the accuracy is about 2mm. This is the most widely used laser infrared range finder. In addition to the function of measuring distance, one can also calculate the volume of the measured object. Infrared rangefinders are widely used in topographic survey, battlefield survey, tank, aircraft, ship and artillery target ranging, measurement of clouds, aircraft, missiles and artificial satellite altitude. It is an important technical equipment to improve the accuracy of high tanks, aircraft, ships and artillery. Because the price of laser infrared rangefinder is decreasing, the industry is also gradually starting to use laser infrared rangefinder, which can be widely used in industrial measurement and control, mines, ports and other fields.
