 Regarding the 3785, as you said, the calibration parameters have indeed improved the performance by 10 to 15%. We replaced the probe earlier, and the performance can reach the specification range of about 1.8 to 1.9.  After further investigation, we found that there was an abnormality inside the probe. It seemed that some kind of dust blocked the pipe.

 Regarding 3789, it is still low induction, need you to check to see if there is any problem?

 For the Qjet air pressure problem pointed out by pascal, we have arranged another one that also has ground sensing, and pressed the ball valve to see if it has an impact on the sensing performance by adjusting the pressure value. It is currently in progress.”
