7.3.3 Gain and detection range (Function B and C)The"Gain"and"Detectionrange"functionsareforfineadjustmentafteranautomaticand/ormanualcalibration;formostapplicationstheyarenotneeded.Alternatively,acalibrationeven without the process is possible only with these functions.

The functions are particularly helpful in the following cases:•Calibrationforapplicationswithlowreflectionorlowsolidflow•Mappingofmovementsintheareasurroundingthemeasuringpointwithnomovement

of bulk solids• Calibration of the FTR20 outside of the process• Adoption of the calibration parameters with a device replacement at the same measuring

point

IntroductionThe FTR20 detects the movement of a wide variety of bulk solids. The total detection range (0 to 100 % = minimum to maximum possible signal strength) is designed to be correspondinglywide.Thiswayevenproductswithverylowreflection(smallsignalstrengths),suchasrigidpolystyrenefoam,canbedetected.

Sincewithmostapplicationsthesignalstrengthsdonotcovertheentiredetectionrange,this can be adapted with function B "Gain" and function C "Detection range".
