      1.The instrument must be vertical: During installation, a 17mm wrench should be used to tighten it, and the case should not be forcibly twisted; Avoid collision during transportation;  

          

      2. The instrument should be used at an ambient temperature of - 25~55 ℃; 

           

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

           

      4. Due to excessive ambient temperature during use, if the indicated value of the instrument does not return to the zero position or there is a difference in the indicated value, the sealing rubber plug on the upper part of the case can be cut open to allow the inner chamber of the instrument to communicate with the atmosphere;

            

      5. The application range of the instrument should be between 1/3 and 2/3 of the upper limit;

          

      6. Isolation devices should be installed for measuring corrosive media, media that may crystallize, and media with high viscosity; 

               

      7. The instrument should be regularly verified (at least once every three months), and if any fault is found, it should be repaired in a timely manner; 

           

      8. 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 from the date of delivery, the company shall be responsible for repair or replacement;
