2.6.9 Connecting the detector to a fraction collector
The detector can trigger a fraction collector based on these things:
• Timed events (see “Timed events” on page 72 )
• Threshold levels (see “Threshold events” on page 74 )
You can connect the fraction collector to one of the detector’s two programmable
switches (SW1 or SW2), and program the timed event, threshold, or ratio at the front
panel. You can also connect the fraction collector to trigger a chart-mark event input
each time a tube is changed at the fraction collector.
