DCR-1006A Level Controller Rev. B2, 7/15 <br /> MAMIS (Maximum Distance): <br /> Sets the distance (in the selected Units), beginning at the sensor face, to the <br /> point where the sensor will stop looking for target echoes. Targets detected <br /> beyond the Maximum Distance will be ignored. <br /> WINdOW (Filter Window): <br /> Sets the width of the target acceptance window (in the selected Units). The <br /> target acceptance window is a zone, centered around the current target read- <br /> ing, within which any target detected will be considered legitimate and figured <br /> into the Averaging buffer. Any target detected outside of the Window will be <br /> considered "out of range" and will be ignored based on the setting in the Out of <br /> Range Samples parameter (see below). The Filter Window extends both direc- <br /> tions from the target reading. For example, if the sensor is detecting a target at <br /> 5 ft. and the Filter Window is set at 1 ft., then any target detected between 4 ft. <br /> and 6 ft. will be accepted. <br /> OUTRAN (Out of Range Samples): <br /> Determines the number of consecutive target readings that fall outside of the <br /> Filter Window before the "out of range" target is recognized as legitimate and <br /> figured into the averaging buffer. For example, suppose the Out Of Range Sam- <br /> ples is set to 10. If a target is suddenly detected outside of the Filter Window, it <br /> will be ignored until it has been detected for 10 consecutive samples, at which <br /> point it will be qualified as a legitimate target. If the "out of range" target was <br /> detected for only 9 consecutive samples before moving out of the sensing area, <br /> then it wouldn't be acknowledged as a target and the reading would stay with <br /> the last qualified target sample. <br /> SAMP R (Sample Rate): <br /> Sets the interval between target readings. Options allow rates from 80 ms to <br /> 1000 ms (once per second). A higher Sample Rate will result in a more rapid <br /> response to target movements. Lowering the Sample Rate will help increase <br /> sensor lifespan and decrease the chance of detecting errant echoes. The <br /> Sample Rate should be set only as fast as is necessary for the application, to <br /> help preserve the life of the transducer. A sample rate of 500 to 1000 ms is usu- <br /> ally appropriate for slow moving tank level appications. <br /> .:.: Automation Products Group, Inc. <br /> APGO <br /> 20 <br />
