Rev. B2, 7/15 DCR-1006A Level Controller <br /> SENSIT (Sensitivity): <br /> Controls the level of amplification applied the returning target echoes (signals). <br /> The sensitivity setting is expressed as a percentage: 0 to 100°/x. <br /> PULSES: <br /> Controls the number of sound wave pulses sent in each ultrasonic burst. The <br /> greater the number of pulses, the stronger the transmitted signal. Range: 0 to <br /> 20 pulses. <br /> BLANK (Blanking): <br /> Sets the distance (in the selected Units), beginning at the sensor face, to the <br /> point where target signals will be accepted. All targets closer than the blanking <br /> distance will be ignored. The blanking should never be set to less than the mini- <br /> mum range specification of the sensor. If the target enters the blanking area, <br /> reading errors will occur. <br /> GAIN C (Gain Control): <br /> Determines how the sensor applies gain to the returning target echoes. <br /> Manual: Sensitivity and Pules remain constant. <br /> Autosense: the sensor continually adjusts the Pulses and Sensitivity (within <br /> the set parameter bounds) in order to optimize the signal strength. <br /> *Hard Target: used for highly reflective targets. Targets echoes at close <br /> range are amplified less. <br /> *Soft Target: used for harder to detect targets. Targets at close range are <br /> amplified more. <br /> *Soft-Auto: autosense using the soft target gain rate. <br /> (*available with MNU sensors only) <br /> AVERAG (Averaging): <br /> Defines the number of target readings that will be averaged together to become <br /> the displayed reading. Each qualified target reading (see Filter Window and Out <br /> of Range Samples on next page) is placed into a first-in, first-out buffer and aver- <br /> aged with previous readings. A higher Averaging will result in smoother read- <br /> ings, but will also slow the response to rapid changes in the target distance. <br /> A P ai� <br /> 19 <br />
