Setting up a run 3-17
Setting up a run
Start a run by pressing the Run/Stop key. Before starting a run, you must set
the detector operating parameters before data can be acquired.
To set up a run
1. Press HOME to return to the Home screen.
2. Set the drift tube heater temperature (see page 3-18 ).
3. Set the gain and gas pressure (see page 3-19 ).
4. Equilibrate the detector for about an hour.
5. Make sure the stop flow output switch is reset (see page 3-21 ).
You need to program several other parameters, depending on the functions
you want to perform during a run. See page 3-15 for function descriptions,
fields, screen number, type of function, display units, allowable ranges, and
default settings for the Home screen and the secondary function screens. You
can view the properties of common chromatographic solvents in the table on
page 6-4 .
