When the Result was Fail
Perform K(Ve) Check after checking the followings and executing Mastering if the result was DET LL or
DET UL.
• Tested part
Check whether the tested part used for K(Ve) Check was same reference master part used for K(Ve)
Automatic Setup.
• Leak
Check the sealing surface for contaminants.
• If test results are not relatively consistent.
Normally extending Pressurization (CHG) timer or Equalization (BAL1) timer will help stabilize the
pressure and consequently the test result will be consistent.
4.2 No-Leak Check

1) Close the both WORK- and MASTER-side stop valves on the rear panel.

Go to:
Set Pressure
6) Press
►
to start a No-Leak Check.
7) Timers are fixed to the follows:
CHG=10.0s BAL1=0.5s BAL2=5.0s DET=10.0s
LS-R700 is not leaking if the result is within ±10 Pa.
If not, contact Cosmo for repair.
8) Press
