radiant heat of the sun can heat the sensor above the ambient
temperature causing the sensor to over compensate for temperature
changes.
ON/OFF
Default: ON
Gain Control (GainCont)
Selects the gain control functions in the sensor.
Manual = user controls the Sensitivity & Pulses
AutoSense = sensor controls Sensitivity & Pulses
Hard Target = user controls the Sensitivity & Pulses
but the gain comes up slower
Soft Target = user controls the Sensitivity & Pulses
but the gain comes up faster
Default: AutoSense
Sensitivity (Sensitiv)
Sets the maximum level of gain that is applied to the echo. If Gain
Control is set to AutoSense, this parameter limits the maximum gain
used by the AutoSense feature.
0 to 100 %
Default: 100%
Pulses (Pulses)
Sets the number of pulses per transmit burst. If Gain Control is set to
AutoSense, this parameter limits the maximum pulses used by the
AutoSense feature. In acoustically active applications or small
enclosed areas, decreasing the number of pulses helps to reduce
multiple echoes.
0 – 16 pulses
Default: 16
Blanking (Blanking)
Sets a dead band distance in front of the sensor. Because of the
physical properties of an ultrasonic sensor, objects cannot be detected
approximately one foot from the face of the transducer. The Blanking
