Pre Evacuation Setpoint A value of -0.70 bar (-0.07 MPa, -10 psi) is
adequate for most applications. This creates 70%
vacuum.
Extended Pre Evacuation To ensure a complete filling. Evacuation will
continue for the set time after Evacuation Level has
been attained.
Gas Locate if Gross Leak If there is a need to locate a leak with a Hand
Probe even if pre evacuation fails. ILS500 will fill to
chosen pressure in Locating Pressure under
Tracer Gas Test.
Locate if Evacuated Below Gas will be filled only if at least set value is
reached. Limits gas spillage through gross leaks.
