TM 5-3895-374-24-1The next internal count reading is 1413 counts. The difference between itand the current average (1330) is 73 counts. This value falls betweenAverage Shift 1 (4) and Average shift 2 (500) Therefore the new value isshifted in once.3rdCyclenew reading123456789101250--?1413*1410141014101410141012501250 1250 1250 out --(lost)- average of 10 registers = 1346 counts = 134 lb. (disp. wt.)--- The next 4 new readings all fall within the same range as the scalehas reached stability after the application of the weight.After 4 more cycles and 4 more shifts the register looks like this:7thCycle1234567891014111412141114121413*14101410141014101410- Average of 10 registers = 1411 counts = 141 lb. (disp. wt.)From the above example note the rapid change in the average countsreading over the first two cycles and the slower change over the subsequentcycles as the average counts approaches the correct reading.If a change in weight on the scale is large enough to make the differencebetween the current average and the new internal counts reading to begreater than 1000 counts (Average Shift Value 3) then the new reading isshifted into the averaging register 10 times in one cycle (full update). In thismode no averaging takes place since all 10 registers record the samereading. This full update mode will continue until the change in the internalcounts reading falls into the range of values below that set by Average ShiftValue 3. Then the averaging system will take over and the weight display willupdate more slowly as it approaches the correct reading.In SummaryRATEOFCHANGEOFDISPLAYEDWEIGHT--- NO REGISTERS LOADEDNO UPDATEAverage Shift Value 1---LOAD 1 REGISTERAVERAGINGAverage Shift Value 2--- LOAD ½ OF REGISTERS12 UPDATEAverage Shift Value 3--- LOAD ALL REGISTERSFULL UPDATEGuidelinesforsettingAverageShiftValue1,2and3Parameters41,42and43AverageShiftValue1 (Parameter 41) - factory set at 3 counts.This parameter should be set for no more than 1/2 of a graduation. i.e. If ascale has been met for 5000 graduations at 60,000 counts then 12 counts =1 graduation. In this case Average shift Value 1 should be set for 4 or 5counts. If set too low then the scale display will appear unstable. If set toohigh then the sensitivity will be reduced and the display may not respond to aone graduation change in applied weight.AverageShiftValue2 (Parameter 42) - factory set at 500 counts.This parameter should be set to two times the amount of change caused bynormal motion while load is on the scale. i.e. for a livestock scale observethe amount of change in raw counts as the livestock are being weighed andset the value for this parameter to twice the observed change.
