Indicates that the leak detector is currently performing a calibration routine.
Indicates that the leak detector is in Test mode. When in Test mode, the Test
Port valve opens and the leak detector is ready for leak testing. Test leak rate
range is 1E-4 to 1E-8 (MDL 5E-9).
Indicates that the leak detector is in Fine Test mode. When in Fine Test mode,
the test port valve opens and the leak detector is ready for fine leak testing.
Fine Test leak rate range is 9E-7 to 1E-11 (MDL 5E-12).
Indicates that the leak detector is in Hold mode. When in Hold mode, all but
the foreline valves are closed, isolating the test port and any test objects or
fixturing from the leak detector vacuum system. Use Hold when you want to
keep the test port under vacuum without venting the test volume; this helps the
system clean up.
Indicates that the leak detector is currently performing a Roughing level
evacuation of the test port and any attached test objects or fixturing attached to
the test port.
Indicates that the optional internal calibrated leak standard valve is open and
that the leak detector is reading the leak value.
Indicates that the test port is vented to atmosphere. The test port and all objects
attached to the test port are isolated from the leak detector internal vacuum
system.
