5.4 Triggering
The measuring value output on capaNCDT 6200 is controllable by an external electrical trigger signal or com-
mand. Here, only the digital output is affected.
Triggering release by:
- Trigger input (pin 3 and pin 4 on 4-pole power supply
connector, see 4.7.2 or
- Software command $GMD, see 6.4.3
- U

The trigger type is determined by
the command $TRGn, see 6.4.2 or
- the web interface, see 6.7.2
Level triggering (high level). Continuous measurement output
