Output of measured values
3.7.1
Free-running output of measured values
The device measures at regular intervals (free-running mode).
3.7.2
Triggered output of measured values
Trigger mode
In trigger mode, the measuring cycle is controlled externally. The device measures in
response to external events (triggers). For example, a scan system and the device can
be synchronized.
The external triggering is possible per measurement up to the measuring rate of 4000
Hz. Each of the trigger modes can be exited by a trigger command (
CTN
).
Trigger modes
•
Trigger Once
•
Trigger Each
•
Window Trigger
Example
Triggers 1 to 6 are triggered externally. The result is returned after the exposure time.
