The following chapter introduces in general the principle of triggering and the con-
trolling mechanisms for the output of the measurement results.
10.5.1
Triggering
In a basic continuous measurement, the measurement is started immediately
after the initiate command. However, sometimes you want that the measurement
starts only if a specific condition is fulfilled. For example, if a signal level is excee-
ded, or in certain time intervals. For these cases, you can define a trigger for the
measurement.
See
Trigger states
The sensor module has trigger states to define the exact start and stop times of a
measurement and the sequence of a measurement cycle.
The following states are defined:
●
IDLE
The sensor module does not execute a measurement. After switching on, it is
initially in the idle state.
When a measurement has been started by one of the
INIT
commands, the
sensor module switches to the WAIT-FOR-TRIGGER state.
See
●
WAIT-FOR-TRIGGER
The sensor module waits for a trigger event.
The occurrence of the trigger depends on the selected trigger source, see
When the trigger event occurs, the sensor module starts measuring, thus
enters the MEASURING state.
●
MEASURING
The sensor module was triggered and is measuring. When the measurement
is completed, the sensor module either continues with the next measurement,
or finishes the current measurement and returns to IDLE state, depending on
the initial mode you have started the measurement before.
