Setting parameters for the S/SL pulsed modes
The pulsed mode parameters are the same as the non- pulsed
parameters, but with two additional values.
Pulsed pressure The inlet pressure you want at the start of
the run. The pressure rises to this value when [Prep Run] is
pressed and remains constant until Pulse time elapses, when
it returns to Pressure.
Pulse time This is the time after the start of the run when
the inlet pressure returns to Pressure.
