Modifying Conditions While Running 143
2. Program and start the autoinjector.
3. Press the Start Run key as soon as possible after the injection occurs.
Note: An Autostart method can override a method that you started with the Start Run
screen key.
Starting the Run-Time Clock
When the controller receives an Inject signal from an injector, the system status changes to
Running and the run-time clock begins counting at 0.00. The system does not accept
another inject signal until the run concludes or you abort the run.
Completing the Method
The system status flag changes from Running to Idle when the method table completes.
The external events remain as set when each analysis completes. They do not
automatically reset to Off. Events that need to be turned on at a specific time in an analysis
must be programmed to turn off before the start of the next injection.
The internal clock continues to run after each analysis completes and only resets to 0.00
with a new injection. Events or gradient segments programmed to occur after the run time
for each injection still occur.
7.4 Modifying Conditions While Running
This section describes how to modify conditions while the method is running, including:
• Changing parameters
• Holding conditions constant
• Stopping flow
• Modifying gradient, event, and detector tables
• Modifying the method table
• Aborting the method
Note: If the keyboard is locked, unlock it by pressing the Unlock Keyboard screen key on
the Pump Setup screen (see Section 4.3.2, Setting Pump Setup Parameters).
