Programming methods and events 3-47
5. Press Enter again to display the list. If you know the event number,
simply press it (see the table titled “Timed event parameters” on
page 3-44).
6. Enter the appropriate selection in the To field if the field appears.
Tip: If you want the same event programmed on both channels, you
must enter two events, one for channel A and one for channel B.
7. Press A/B to set the threshold on the other channel.
Tip: ON A or ON B indicates the channel on which the event is
programmed. You can program all or some events on channel A and all
or some events on channel B. Event programming is time-based, not
channel-specific.
8. Press Next to advance to a new timed event. To delete a timed event,
press CE when the time field is active to change it to OFF.
9. Press HOME to return to the home screen, then press Run/Stop to start
the method.
10. Select Reset (Shift, Run/Stop) to reset the run clock to 0.
Tip: If the detector is configured with the 717plus Autosampler or other
external device, the inject-start signal programmed from that device
starts the method.
Programming threshold events
You can program threshold events on channel A and channel B to control the
switch contact closure outputs as when using a fraction collector. Program the
switch to change when the programmed output (fluorescence/EU, energy, etc.)
on the channel is above a specified threshold. The following table lists the
contact closure switches you can program.
Caution: When you are working in real time, under current
conditions (method *), a power failure or shutdown causes loss of
all timed or threshold events if you do not store them as a method
(see page 3-49).
