The graphs below show when sampling is triggered while [Rising] is specified for [Trigger
Edge]. The graphs show changes in sampled values over time, and the left end of the graph
is when the sampling operation is executed.

Trigger Level
Sensor: The sensor is always [Motion] for this start trigger. Sampling is triggered
in accordance with the input value of the motion sensor connected to the
SONIC channel. The timing of the trigger is controlled in accordance with
the following two parameters.
Trigger Threshold: Specify a threshold value to specify when sampling is triggered.
Trigger Level: Select either [Above] (any value above the [Trigger Threshold] value) or
[Below] (any value below the [Trigger Threshold] value) for this
parameter.
Tip
• With this start trigger, sample triggering depends solely on whether the current input value is
greater than or less than the trigger value. When [Above] is specified for [Trigger Level], for
example, sampling will start immediately if the input value is already greater than the specified
threshold value when the sampling operation is executed.
• When specifying the Trigger Threshold, be sure to specify a value that represents a relatively
significant change for the current or normally measured value. A threshold value that is too close
to the current or normally measured value can cause problems with triggering.
