7.5 Fast Fill
A Fast Fill (or Prefill) operation can be performed for testers fitted with an
electronic pressure regulator when testing large volume or flexible components to
reduce cycle time. This is achieved by setting Fill 1 step parameters to pressurize
the test part to typically 10 to 20% above the test pressure for a predetermined
duration and Fill 2 step parameters to achieve the required final test pressure.
Notes:
1. The upper pressure tolerance during Fill 1 and 2 steps will be set to the highest
level of test pressure 1 or 2 plus the pressure tolerance.
2. The lower pressure limit is checked at the end of each step based on the set step
test pressure – pressure tolerance.
