Just started to use PE 650. Have issues with the leak test. Any suggestion/advice is appreciate.
The leak test first failed (10psi difference between initial and final pressure), so replaced orings and filter in the fixed and mobile assembly. However, there is still 1 psi difference between initial and final pressure. Shut down and Restart the instrument, the pressure difference is reduced to 0.3-0.5 psi. It would probably pass the leak test, but still wonder any other parts need to be fixed/replaced? why is this happening. Million thanks.
