7.4.4 Triggering
7.4.4.1 General
The optoNCDT 1220 measurement output is controllable through an external trigger signal or a command.
Triggering affects the analog and digital output.
The measurement value at the time of triggering is output
delayed, see Chap. 6.3 .
- Triggering does not influence the timing so that between the trigger event (level change) and the start of
output always lie 3 1 cycle (Jitter).
- The multifunctional input is used as external trigger input, see Chap. 5.4.7 .
- Factory setting: no triggering, the sensor starts data transmission right after start-up.
- Pulse duration of the “Trigger in“ signal must be at least 50
µs.
