Step1. Cleanup & aging
Perform Cleanup and leave it for a while in "Test state". The effect will be recovered after inhaling a large amount of He.
Step2. Jig seal check
Check the test port, jig flange surface, and O-ring for scratches and foreign matter. BG will not drop if there is an external leak.

Conditions such as lack of OIL and white turbidity (mixed with water) can cause an increase in the background.
Step5. Inspection and Maintenance by The Manufacturer
