Programming methods and events 3-37
If the detector is configured with the 700 Series Autosampler or another
external device, the inject start signal programmed from that device
starts the method.
Tip:
If you are working in real time under current conditions (method *),
and a power failure or shutdown occurs, you lose all timed or threshold
events if you did not store them as a method (see page 3-38 ).
Programming threshold events
You can program threshold events to control the auxiliary switch.
Below the specified threshold, the switch is set as shown in the table, below.
You can program the switch parameters listed in the table.
To define the pulse period, or the frequency of a wave, see page 3-26 .
To program a threshold event
1. Press METHOD (press Shift, TEMP
°
C) on the detector keypad. The
Method choice list appears.
2. Press 2 Threshold events. An active field (LSU) for entering the
threshold appears. When you begin to enter a number in the LSU field,
additional fields appear.
Tip:
The threshold selection provides the means to modify this initial
Threshold value as a timed event.
