Q: Why does the follow-up measurement after a gross leakage return a leakage

rate that is too small?

A: Especially after measuring a gross leak, you should purge the measurement line

for at least 4 s with low-helium air, then wait for 1 s before performing the next

measurement.

This removes the residual helium, which could otherwise affect the following

measurements, from the measurement system.
