Selective Adsorption Mode
Evac Time The amount of time the system evacuates the sample tube between
pressure points when Selective Adsorption Mode is enabled.
Sampling Pressure After equilibration, the system will vent the manifold to this
pressure before triggering the external device to collect data.
Trigger The voltage and the amount of time the trigger signal is sent to the
external device.

Vent/Vacuum Threshold
Above this pressure the system will use the vent servo or needle
valve to reach desired pressures, below this pressure the system
will use the vacuum servo or needle valve to reach desired
pressures.
Vent Line Flush
Flush if Below If any dose pressure in the isotherm analysis is below this value,
the system will flush the vent line with the analysis gas before
pressurizing the manifold to the dose pressure.
This prevents contamination of the manifold during venting at
near-ambient pressures.
Fill time The amount of time the system will fill the manifold with the
analysis gas prior to the vent line flush.
Vent time The amount of time the system will open the vent valve to flush
the analysis gas through the vent line.
