Select the High Pressure Test mode. When High
Pressure Test is selected, Range Stop defaults to 10

is 10
-4
to 10
-8
atm cc/sec.
When the leak detector is in Vent mode:
Turn the High Pressure Test feature on to start the
test cycle. This automatically locks the leak
detector into Contra-Flow™ Leak mode, and auto-
ranges through all decades down to the most
sensitive Contra-Flow range.
When the leak detector is in Test mode:
Turn the High Pressure Test feature on to perform
the same function, with the exception of
performing the test cycle start sequence.
Select the Fine Test Only switch to enable the feature.
When selected and Test is initiated on the Home
Screen the leak detector transfers from Test to Fine
Test and remains in Fine Test regardless of leak rate. If
the test port pressure is greater than 1.4E-1 Torr the
leak detector transfers back to the Roughing Mode.
