I am working with a 7890B. I recently conducted PMs. Before the PMs I conducted an inlet leak test and the test passed as normal. After the PMs were completed the test results are giving me a total flow of 8.76 and a col flow of 19.6. This seems like the opposite of a leak. I looked for a clog and replaced the septa the liner and the gold seal. The liner when I replaced it looked like the gas was moving toward the inlet instead of the normal path. I tested my standards and the RTs were about 100% later than normal and the peaks were about 20% of the normal size.
