5.7 Triggering
The Triggering configuration tab allows the configuration of the parameters used as
thresholds to trigger the waveform and disturbance recorders.
5.7.1 Thresholds
This screen allows the configuration of thresholds associated with measured and
calculated values (from the analog channels) that once exceeded can cause the DR60
recorders trigger.
Following parameters can be set for each defined threshold:
Parameters set for each defined threshold
Parameter
Range
Step
Hysteresis
0 … 20 %
0.1 %
Hold time
0 … 1000 ms
1 ms
The thresholds are displayed side by side to easy and quick configuration. Upper and
lower thresholds are represented by the following signs:
Threshold

Example
Upper (Over)
Over Frequency – F (Hz)
Lower (Under)
Under Frequency – F (Hz)
Blank threshold will not be processed and will not trigger the recorder.
