3-48 Using the Detector
Below the specified threshold, program the switch parameters as in the table
below.
To define the pulse period, or frequency, of a wave, see page 3-25.
To program a threshold event:
1. Select METHOD (Shift, A/B) on the keypad. The Method list appears.
2. From the method list, select 2 Threshold events.
An active field (EU) for entering the threshold appears. When you begin
to enter a number in the EU field, additional fields appear.
Tip: The threshold event allows you to specify a threshold value (EU)
that triggers a switch if the fluorescence signal intensity rises above the
value you entered.
