Precautions when using the pressure gauge

1. The instrument must be vertical: a 17mm wrench should be used to tighten it during installation, and the case should not be twisted strongly; Collisions should be avoided during transportation;

2. The instrument should be used in the surrounding environment temperature of -25~55 °C;

3. The vibration frequency of the working environment <25HZ, and the amplitude is not more than 1mm;

4. Due to the high ambient temperature in use, the indicator value of the instrument does not return to the zero position or the indication value is out of tolerance, the rubber plug sealing on the upper part of the case can be cut to make the inner cavity of the instrument communicate with the atmosphere;

5. The scope of use of the instrument should be between 1/3~2/3 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 instrument should be checked frequently (at least once every three months), and repaired in time if a fault is found;

8. From the date of delivery, if the instrument is found to be invalid or damaged due to poor manufacturing quality under normal storage and use conditions within half a year, the company shall be responsible for repairing or replacing it;

9. The instrument that needs to be used to measure corrosive media should indicate the requirements when ordering.
