Triggering

5.7.1 Thresholds
53
The Triggering configuration tab allows the configuration of the parameters used as
thresholds to trigger the waveform and disturbance recorders.
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
Hysteresis 0 ... 20 %
Hold time 0 ... 1000 ms
The thresholds are displayed side by side to easy and quick configuration. Upper and
lower thresholds are represented by the following signs:
Threshold Sign
Upper (Over)
Lower (Under)
Blank threshold will not be processed and will not trigger the recorder.
Below is the list of all possible thresholds:
