Precautions when using pressure gauge

1. The pressure gauge must be placed vertically during prevention and treatment: tighten it with a wrench during installation, and do not directly twist the outer shell with your hands, because this will damage the shell. Do not let it collide during transportation to avoid damage.

2. When using the pressure gauge, pay attention to controlling its amplitude below one millimeter.

3. During use, if the pointer of the instrument cannot return to zero due to the high temperature in the environment, you can cut the rubber plug on the case to allow the atmosphere to enter the instrument to easily solve this problem.

4. When using the instrument, pay attention to the external temperature and control the external ambient temperature between -25 and 55 degrees. Only within this temperature range can the pressure gauge work normally and not be damaged.

5. The pressure gauge should be checked regularly during use. The inspection cycle is at least once every three months. If any fault is found during the inspection, it should be repaired in time.

6. The use of the pressure gauge also has a certain range, which should be controlled between one-third and two-thirds of the maximum value of the pressure gauge.
