SENSIT (Sensitivity):
Controls the level of amplification applied the returning target echoes (signals).
The sensitivity setting is expressed as a percentage; 0 to 100%.
PULSES:
Controls the number of sound wave pulses sent in each ultrasonic burst. The
greater the number of pulses, the stronger the transmitted signal. Range: 0 to
20 pulses.
bLANK (Blanking):
Sets the distance, beginning at the sensor face, to the point where target signals
will be accepted. All targets closer than the blanking distance will be ignored.
The blanking should never be set to less than the minimum range specification
of the sensor. If the target enters the blanking area, reading errors will occur.
GAIN C (Gain Control):
Determines how the sensor applies gain to the returning target echoes.
Manual: Sensitivity and Pules remain constant.
Autosense: the sensor continually adjusts the Pulses and Sensitivity (within
the set parameter bounds) in order to optimize the signal strength.
*Hard Target: used for highly reflective targets. Targets echoes at close
range are amplified less.
*Soft Target: used for harder to detect targets. Targets at close range are
amplified more.
*Soft-Auto: autosense using the soft target gain rate.

AVERAG (Averaging):
Defines the number of target readings that will be averaged together to become
the displayed reading. Each qualified target reading (see Filter Window and
Out of Range Samples on next page) is placed into a first-in, first-out buffer and
averaged with previous readings. A higher Averaging will result in smoother
readings, but will also slow the response to rapid changes in the target distance.
