What problems should be paid attention to when using precision pressure gauges:
1. The meter must be vertical: a 17mm wrench should be used for tightening during installation, and the case should not be forcibly twisted; collisions should be avoided during transportation;
2. The temperature of the surrounding environment should be -25~55℃;
3. The working environment vibration frequency is less than 25HZ, and the amplitude is not more than 1mm;
4. Due to the high ambient temperature during use, the indicating value of the instrument does not return to zero or the indicating value is out of tolerance, you can cut the sealing rubber plug on the upper part of the case to make the inner cavity of the instrument communicate with the atmosphere;
5. The use range of the instrument should be between 1/3 and 2/3 of the upper limit;
6. Isolation devices should be added when measuring corrosive media, media that may crystallize, and media with high viscosity;
7. The meter should be checked frequently (at least once every three months), and if any malfunction is found, it should be repaired in time;
8. If the meter is found to be invalid or damaged due to poor manufacturing quality under normal storage and use conditions within half a year from the date of leaving the factory, the company will be responsible for repair or replacement;
9. An instrument for measuring corrosive media is required, and the required conditions should be indicated when ordering.
