RANDOM PULSE 1-6 (0 to 120 msec.)
The RANDOM PULSE parameters are used to set delays between samples from
each of the six front-end circuits. By assigning varied delays between samples,
the user can reduce transducer cross-talk and multiple-echo interferences. The
default settings have been used with good results and should not need
adjustment in most applications.
DETECT ADD (0 to 1 m)
The DETECT ADD feature “adds” a detection zone (of the specified length) in
front of the SLOW zone (see figure below). If an object enters the DETECT
ADD zone, then the sensor increases the sample rate and starts random pulsing.
This is designed to increase the response time of the sensor should the object
enter the SLOW zone.
