2.7 Theory of Operation
2.7.1 Understanding the Wait Operation
NOTE This section pertains to AS operation in
Local/Schedule Control mode (see Section 2.5.1 )
only.
The wait operation is a step in the sample prep phase of a method. After
performing all other sample prep steps, the AS waits for a continue
command before performing the method’s timed events. The continue
command can be sent via the front panel
Hold/Run
button or a TTL input
signal.
The wait’s position in the sample prep steps determines whether samples
are overlapped or run sequentially:
•
When the wait operation is the last step in the sample prep phase (the
default), samples are overlapped (see
Section 2.7.2 ).
•
When the wait operation is at the beginning of the sample prep phase,
samples are run sequentially (see
Section 2.7.3 ).
NOTE The wait operation can be disabled (see
Section 2.7.4 ).
